Transcript of Tiger Adaptations Project

Tiger
Adaptations Let's start with structural adaptations
of the tiger. A tiger's stripes aren't just for good looks. They are an adaptation that helps them camouflage in their habitat. It resembles beams of sunlight finding their way through trees' canopies, and makes the tiger very hard to detect. Tigers are very strong. Their flexible spines and long legs allow them to horizontally jump up to 33 feet! This makes them very suitable for catching prey, running and swimming. The tiger has also developed sharp teeth and claws. They use their claws to snag their prey, and their teeth can tear it apart. A tiger also has soft pads and retractable claws on it's paws. The soft pads allow the tiger to sneak up on its prey while walking on its toes. The claws are used for killing and grabbing, and can retract behind a sheath of skin so they aren't worn out. One behavioral adaptation is that
they hunt alone so that they can
surprise their prey. They scratch their claws on "scratching posts"
(trees) to keep them nice and sharp. Tigers have a very keen sense of smell. This helps sniff out prey and other tiger's territories. Tigers have rather strong eyesight. This helps them pick out their prey from a far distance. A tiger's coat keeps them cool in the summer and warm in the winter. This adaptation is important for their survival. Behavioral adaptations include: Behavioral adaptations include: We think that mutations could change a tiger's teeth so it is shaped more like a human's. This would allow them to eat leaves as well as meat, once the amount of prey they have starts to decrease. Survival of the fittest may also help them develop longer and stronger claws (even though they already are) to fight other tigers for territory and food. The cattle egret and cattle demonstrate commensalism. While the cattle are grazing, they tend to move and stir the grass around, which exposes insects. The cattle egret is then able to find insects easily without affecting the cattle or horses that are grazing. Oxpeckers and zebras or rhinos demonstrate a mutual relationship. Oxpeckers land on the zebras or rhinos and eat ticks and parasites living in their skin. The oxpeckers get food, and the zebras and rhinos don't have to worry about ticks and other parasites. Also, when there's danger, oxpeckers will fly upwards and let out a warning scream, alerting the zebra or rhino. The sweet mistletoe that you have hanging on your door is actually a parasite. While they may seem like a harmless Christmas decoration, they actually grow attached to and between the branches of trees. They use the tree as a home, and steal the nutrients it needs. Make sure to be safe the next time you see a mistletoe leeching the nutrients from a harmless door. Were you able to catch it? If you didn't see the caterpillar, go back and double-check. That was a green caterpillar hiding on a leaf. Pretty cool, isn't it? They use their camouflaging abilities to hide from their main predators: birds. It also works well because once they're done hiding, they've got something to eat! Sting rays use mimicry, which is very similar to camouflage, to "act" like sand. They dig into the sea floor and cover most of their bodies with sand or gravel, which other fish won't notice. Their eyes are the only body part showing, which allows them to determine when it's clear to come out of hiding. That was a peacock butterfly, with its wings open, showing off bright colors. It also looks like two eyes on the tips of the wings. The peacock butterfly flashes its bright colors on the top of its wings when a bird or other predator is about to attack, which actually works. Many organisms adapt to their environments and change over time. They are able to do so because of mutations in alleles which change different characteristics of an organism. These changes are then passed on to future generations, and further adapt. Survival of the fittest also plays a big part; organisms compete to survive, and in doing so, develop characteristics which help them survive against the others. Darwin's finches proved his theory of "survival of the fittest" by demonstrating the different beaks the finches had, which adapted to the environment and the food that was available. The vegetarian tree finch has a beak adapted to fruits. It's beak is shaped like a parrot's, allowing it to grab the whole fruit. Insect-eating finches mainly have grasping beaks to hold the insects in place so they don't fly away. The cactus-eating finch has a probing bill to dig inside the cactus and pull out more from it. Seed eaters have bills that are powerful and can crush seeds. Penguins could adapt the physical ability of growing larger in order to protect themselves from predators. This could happen if the few penguins left have more food, and are able to get more nutrition and grow more. Tigers could adapt behaviorally by doing some sort of movement that could show another tiger they could make a team and work together to find food. If there aren't many tigers left, there will be more predators that could attack them, and working in groups could be an effective way of acquiring and sharing food.
