  1. I noticed that dolphins adapted to their environment by stirring up the sand in the water to cause the fast fish they prey on to jump out of the water and so the dolphins could catch them and eat them. Camelions use camoflauge by changing their skin color either to blend in or to attract mates. They also use long quick tongues to catch bugs to eat them. Lastly, I saw that komodo dragons used venom to slowly weaken their large prey of a buffalo so that they could eventually watch it die, then eat it.

  2. I saw that like the komodo dragon adapted to there environment by having venom that will kill large animals like the water buffalo and then they can eat to survive. Other animals have adapted to protect themselves from other predators by changing there color like the camelion. The camelion in the desert have the adaptation to be able to changed the skin color to absorb heat and stay warm.

  3. When I watched the videos, i saw that many different organisms have very different habits when it comes to survival. Some try to escape while others try to fight back. Sometimes certain types of species fight over who is allowed to produce offspring and who isn't. Also, different species try different techniques to try and ensure their offspring survive while others just leave after they lay their eggs.

  4. In the video, some of the beneficial adaptations including the hunting skills, jumping into the thin air, and conserving energy. The dolphins adapted by creating a ring of dust around fish, scaring them into jumping. The pebble and the waterfall frogs jumped from the tops of the trees and rock structures to avoid their predators. The crocodile conserved energy by lining up across the river and letting the fish come to them. The stalk-eyed fly adapted to for mating rights, as the fly with the longest eyes got the rights to mate with the females. The chameleons adapted by being able to change color to match their environment and use their long tongues to capture their prey. The komodo dragon’s ability to use venom to take down an animal much larger than itself was how it adapted to get the food it needed.

    All those animals adapted to their environments in different ways, but all benefitted their ability to eat and not be eaten by predators.

  6. Animals adapt to allow better survival skills and in the video it gave examples of some of these animals. Chameleons blend in with there environment to hide from predators and sneak up on pray. They also have long tongues that allow them to catch food from far distances so they wont scare there victims. Komodo Dragons have a poison in there saliva which allows them to take down large animals in a single bite. Some lizards are so small that when it rains it can cause them to drown, some are even small enough, and have substances in there skin that allow them to float on water. These are just some of the ways animals have adapted to life.

  8. The chameleon that walked on the desert sands under the strong sun, adapted by being able to turn a lighter shade to keep cool from the hot sun on one side of its body(the side that would be exposed to the sun) and a darker shade to keep warm(the side that was in the shade). Also, the Komodo dragon has strong venom that can kill animals as large as a water buffalo, so they could eat. The snakes that would come out of hibernation and bundle up together so they could all provide heat for one another, and when the last snake came out of hibernation later than the rest, he let out a female scent so the other male snakes would come to him and bundle over him, that way he could get their heat!

  9. Most of the reptiles could change the color of their skin which is benefical to them because then they can hide from their predators. Komodo dragons used there venom to poison their prey then wait it out until they became to weak to move. Most of the lizards we saw waited on branches and blended in with the color of the branch and then wait for their prey and catch them with there super long tongue. Only the strong males though were allowed to pass on their traits. They had to win and show their strength or they had to have genetic traits that wooooo'ed the females.

  10. One female chameleon, while roaming in the desert looking for a mate, adapted to the warm weather and blazing sunlight. The side of her body that faced the sun was of darker color to attract the sun and warm the reptile up. The other side was white to keep the sun from venting out. This reptile's skin was two-tone to help keep it warm.

    The dolphins used an adaptation to help hunt. These particular dolphins worked in a group with a leader. The leader beat his tail in a circular pattern to stir up dust ring, entrapping all the fish inside. Panicked, the fish began jumping or "flying" as the other dolphins gathered around the ring and caught the flying fish in their mouthes for food.

    The large bulltoad didn't necessarily adapt, but he used his resources to save his along with the other toad's young. When the water source or puddle dried out, he used his large size and dug a channel between the puddle and the large water source. The tadpoles were able to swim to the water source through the channel. With out the male toad's actions, the tadpoles would have dried up in a couple of hours.

    Small lizards have made many adaptations to benefit their small size. First off, these tiny lizards, that are small enough to sit comfortably on one's fingertips, are very quick. They can easily outrun predators like insects. However, small rain drops could easily drown the lizards, so they adapted waterproof skin over time. Their skin is inpenetrable to rain. Lastly, because there is the possibility of drowning and because the lizards are so small, they float in water. These tiny lizards can go on land, outrun pradators, have skin inpenatrable to water, and they can walk on water. This particular species had many beneficial adaptations, and survival is easier for them than for other organisms and species.

  11. there was a lizard that the skin is water repellent and can float on water because it is so light and stuff

  12. My favorite adaptation out of all the ones that we saw was the lizard that was able to walk on water. The lizard would have been an easy target had it ran into the forest like a normal lizard. Instead, previous generations decided to develop the ability to run fast enough and hard enough to only sink a few inches into the water. This was due to the width of the feet and the velocity of the legs pressing down into the water. The predators, in this case birds, were left confused and hungry. A new adaptation for the future would involve fish that would be able to see the lizards running on the surface and hunt them from the water.
    Another cool adaptation was the Pebble frog. The frog is about the size of a fingernail, but this is its best feature. Due to the weight of the frog and the toughness of its skin, the frog is able to jump from its place high up in the cliffs and bounce all the way down the hillside to the bottom. There is not enough weight for gravity to crush them, so they are able to bounce right back up and hop away. This is extremely helpful in escaping prey, as the hunters cannot chase the frog down such a steep decline.

  13. There was dolphin that could kick up sand as it swam in a circle to trap a bunch of fish. Just as the fish would jump up the dolphin would eat them. Another adaption was tiny lizard that was fast enough to get away from any predator. It was also so small that it could float on water. Another lizard was able to run on water to escape any of its predators. There was a chameleon that could turn half its skin dark to get more sun and then the other half white so the heat stayed in. There was a pebble toad that lived up in high rocks and any time a predator attacked it would roll up like a pebble and then fall down the rocks until it was out of the predators reach.

  14. Crocodiles waited in the water for fish to come to them as a way to make catching prey easier. Some toads fall from trees and roll away from predators, they can do this because they are so light weight and rubbery it doesn't harm them.
    Some lizards can run fast enough to run on water away from their predators. There is a very small lizard that can be harmed from a single water drop, but has skin repellant from water so it can stand on water. Walking sticks evolved to look like sticks so they can hide from predators

  15. All animals have their ways of adapting. They have ways of protecting themselves, finding food, and surviving. The komoto dragon has a certain way of finding food. In the video, they bit the buffalo and since the komoto dragon has venom, it took three weeks for it to get really weak. They would follow it around until then. Komoto dragons are like sharks, the smell of blood attracts other komoto dragons. Iguanas are able to change the color of their skin to not be seen. There is a small lizard that is able to stand on water it is so light. When water hit him, for example a raindrop, its skin didn't absorb it. There are so many different ways for all kinds of animals to survive.

  16. The chameleon that walked on the desert sands under the strong sun, adapted by being able to turn a darker shade to absorb the rays of the sun on one side of its body(the side that would be exposed to the sun) and a lighter shade to keep the heat in the body(the side that was in the shade). Also, the Komodo dragon has strong venom that can kill animals as large as a water buffalo, so they could eat. The snakes that would come out of hibernation and bundle up together so they could all provide heat for one another, and when the last snake came out of hibernation later than the rest, he let out a female scent so the other male snakes would come to him and bundle over him, that way he could get their heat!

  17. In the video there were many different adaptations that were beneficial to all types of species. For example the stock eyed fly could stretch its eyes out to see predators from all angles. Another example would be the Komodo dragon and it had to adapt to its environment in order to get food. The venom makes it the largest venomous animal in the world. The chameleon also has very unique adaptations, its skin can change color to stay away from prey and keep a reasonable body temperature in hot climates. To trap food dolphins create an allusion to trick the fish and bring them right into the dolphins mouth, this shows that animals have to adapt to the way their prey think and live. Snakes also had to bunch up together to regulate their body temperature after a cold hibernation. The “Jesus Christ” lizard was so light and fast it was able to run over the water without drowning, this is a helpful adaptation to stay away from lurking birds. Over time animals have made huge advances to keep their species growing and thriving.

  18. there were many adaptations that were shown in the amazing video. one example was the camoflage on the chamneleons. this helped them hide in the forest and in the desert it helped them to keep warm. they could have adapted in the past when there could have been all white chameleons in the past and they would have trouble surviving and staying warm. so one could have mutated to cahnge color and it would have survived and passed on it's genes. the pigmey newt could have addapted in the past from a larger newt that couldn't stay above water.
    the komodo dragons could have adapted to get their venom because in the past they could have not had venom and had a harder time taking down larger pray due to their stocky build. so they started producing venom through a mutation which helped them take down larger pray. the frogs that couldn't jump may have adapte their brain skills to learn a different way of getting away from predators like falling. the killer wales adapted their hunting techniques to be able to hunt seals instead of small fish. the penguins addapted their feathers to be small and water tight so they could swim faster and better. the underwater snakes addapted the fin on their tail so they could swim better.

  19. All of the adaptations I saw helped the creatures to survive. Many of them involved color. The chameolons used camoflage to hide in thier enviornments. Also in the the desert they used there color changing ability to stay warm and keep warm. Other color abilitys allowed animals to stay hidden and use the element of surprise.
    Another adaptation I noticed had to do with water. The small pigmy newt could stay on top of water because of its water repellent skin and size. The basilisk lizard could also run on water to escape and confuse aerial predators. The one birds that danced on water as a mating ritual also comes to mind. All of these adaptations may have originated from one common ancestor but differed through evolution.
    Some creatures used their adaptations for mating rights. Again the birds danced on water for mating rights. An odd insect enlarged its eye stalks to attract a female. Frogs, Hippos, and snakes all fought for dominance of mating rights. All these adaptations have helped the species mate.
    Those are the main adaptations I saw in the video Life.

  20. The dolphins that caught fish by trapping them and forcing them to jump had adapted in strategy not physically. They were the only ones that could do this in the world and it helped them catch prey more efficiently. The tiny lizard that was smaller than an insect was fast enough to escape prey and could defend itself from the dangers of being small with its waterproof skin. The lizard that had the unique strategy of confusing its predators had a better chance at survival because it did not act normally and looked more dangerous. The Jesus Christ lizard could run across water gaining precious seconds so it was not eaten. The tree frog jumps from a tree and grabs a branch on the way down effectively evading its predators.

  21. In this video I saw many adaptations to the enviroment. The coolest one that i saw would have to be on the komodo dragons. Komodo dragons are 9 feet long and are one of the most poisonous animals in the world, this is a bonus for them. Komodo dragons only live in hot enviroments, and to survive they have to kill bigger animals such as buffalo. They had to adapt to the enviroment and become larger and stronger then the rest of the animals. Another adaption that I thought was pretty cool was the Pebble Frog. The Pebble Frog has a feauture where when a predator is chasing him all he has to do is find a ledge and jump off. His body acts as a rubber ball that bounces all the way down until it stops. The mini gecko also had a pretty cool adaption to the enviroment. They are so light they can float on water,a and they are so fast that they can escape from just about any predator. They have a different skin type where they cant get wet. I also liked the adaption of the cheetah because they hunt together to take down ostriches.

  22. I thought that the coolest adaptation was when the pebble frog went limp and bounced down the mountain like a rubber ball. It doesn’t even get hurt from it, and it developed this adaptation so that it could escape from predators like the tarantula. Another really cool adaptation was when the Jesus lizard ran on water. Earlier generations of the Jesus lizard found that birds were eating them to much because they were just running into the forest. So they decided to be unpredictable and jump into the water. Over time they adapted and were able to run on water. I also liked that the chameleons had super long, rocket like tongues. They developed this so they could creep up to their prey and just shoot their tongue at it and eat it. I also found the flying fish really interesting. In order to escape swordfish eating them these fish grew wings and can glide for a long time in the air. I also found really interesting when the mini gecko floated on water. Due to its very small size and super water resistant skin it is able to float on water. It was also really cool when the cheetahs took down the ostrich. They are one of the fastest animals on earth and due to that they can catch animals like the ostrich. Even though they are really fast, they aren’t that strong so they can’t take down something to big like an ostrich, so they work together to bring it down.

  24. Many of the adaptations in the video can be categorized. Some had to do with offense. Animals would develop new hunting techniques,effective weapons, and intricate tools. Others developed defensive skills. They aquired mothering techniques and survival skills. Also, most organisms need to mate, so many animals have perfected the art.
    Some animals develop new hunting skills or processes. This is due to their developing intelect, not their physical condition. The bottlenose dolphins, one of the smartest animals on Earth, have done such a thing. Because of their need to catch fast moving fish to eat they used their superior intelect to trick the fish into literally jumping into their mouths. Along with the dolphins the cheetahs have improved their hunting skills. As their intelegence increased they learned to work together allowing them to bring down animals much larger than they are. The kapuchan monkey also used its smarts to outwit not another animal but a plant. They developed tools that allowed them to crack open the hard seeds of plants. Other animals owe their success not to intelegence but to favorable genetic traits. The chameleons toung, eyes, and camoflauge all help it in successfully hunting its prey. The venus fly trap has perfected the ultimate trick and trap technique.
    All of those used their skills and traits to hunt. Other organisms use them to survive. Crab eater seals use their athleticism and agility to avoid killer whales. Flying fish have adapted light weight bodys and overgrown fins so that they are able to fly away from predators that can not reach them in the air.
    All animals need to reproduce to carry on their species. That is why a select few have adapted extreme mating and mothering skills. The mother octupus sacrifices herself to pretect and assure the safety of her eggs. The mother dart frog will carry each of her eggs up a tree and feed them unfertilized eggs so they can grow. Hippos fight for dominancy to reproduce. The stalk eyed fly dedicates itself to producing a worthy dislplay for a mate.
    In all, animals and organims will adapt and do what it takes to survive.

  25. All living organisms somehow tie into adaptation. Wheather it's eating other animals to survive, or protecting themselves, or their eggs, from predators.
    In the movie, I saw many examples of adaptation. From bulls to insects, I saw the adaptaions. I saw the pebble frog climbing up the mountain top. He adapted by seeing a predator, and making himself into a small pebble-like figure, falling down the mountain top. Another example is the small lizard. When seeing his predator in the sky, he jumped off his tanning spot and splashed into the water, walking on the water with his "Jesus Christ" legs. Or the iguana, changing its colors to make himself blend in.
    There are many types of adaptaions. The one I just explained was the adaptions of protecting yourself. There is also the adaption to help yourself survive. Everyone needs food to survive, and killing other animals is just a part of life. For example, when the baby penguins leave their mothers, they have to battle through the icey water to get to open water. But they dont know how to protect themselve yet. The seal knows this and attacks. Waiting for its next pretator. Another example is the dragon. He needs to survive and needs a large feast. The dragon has a bite like a snake. When they bite the prey, they soon get weary and weak. Once they are weak, the dragon attacks again. Killing him, and sharing him with other dragons.
    The other type of adaptation is the laying the eggs and mating, creating new generations. The lizard in the deserts rarly find a mate, and when they do, they cant stand regection. So, they fight the females, makign them weak and plant the sperm, making the next generation. Many mothers have to risk their lives to carry on the generation. For example, the fertilized octopose lays her eggs in the cave. After many months of laying in the cave, protecting her eggs, starving, the eggs hatch by her send a pressure of water on them. The mother then dies. Another example of this is the frog. When the frog lays its eggs it stands by them, protecting them. Once they hatch, they need water. She forces each of them on her back, taking each of them to their own place in a leaf. After that, she has to feed each of them. Now they are in seperate places, this wearies her out. She feeds them unfertilized eggs until they grow larger and be able to come out of the water, and be on their own.
    Many oraganisms prey on eggs. Such as the snake, trying to eat the eggs of the lizards. Some lizards are succussful of shewing them off, some are not, and have to wait until next year to breed again, knowing now what to do.
    Adaptaion can be sad and it can be happy. It is a part of life. Every organism has adaptation.

  26. The adaption that i noticced the most in yesturday's video would be that of the chameleon being able to change the color of its skin to blend with surrounds of it's enviorment and the way its tounge can shoot out at 15mps to catch unsuspecting prey.

    Another adaption i had noticed was about the lions working as a pack. The ostrich seeing only one of the three had not suspecting anything to be amiss, but when the other two put in the charge, all bets were off. being taken by three of the normally solo hunters, the ostriches were caught off gaurd and taken for the kill.

    The best one i can think of is that of the pebble toad. Its adaption was to be as small as possible;this alloud him to fall off the mountian top and land at the bottom safe and sound. Being so light alloud him to be unharmed by great falls, bouncing and rolling just as a pebble would.

    My second favorite would be the Jesus Crist Lizzard, being able to to run fast enough to walk on the watter. this allous it to run from the birds of prey that would surely kill if it fled into the surrounding trees.

    The last one i remember is that off the dolphins working as a group to hunt for fish. They swam in a circle to kick up sediment and cause the fish to believe they are trapped. The fish would then willing jump out of the watter though unwittingly into the mouths of the dolphins.
