Animal Behaviors

An Innate behavior can be said to be an inborn behavior. One of the innate behaviors shown in the clip is the chameleon’s ability to reach for cover and adapt with the environment and to feed. The predatory behavior of the chameleon can be seen in its feeding, it brings out its tongue to pick a prey in a fast way. It is important because it enables it catch their prey so that they don’t escape. The eyes of the chameleon moves round in any direction, without the head moving along with it.

The adaptive advantage of the chameleon’s eye is that it helps them to see what is happening around them and can also help them to look out for predators, as well as look for preys. Flying Lizard: Yes the lizard’s wings are homologous to a bird’s wings. They are homologous because the lizard’s wings are folds of skin, supported by ribs that extend out wards from its body, while in the bird; its forelimbs are modified as wings. The bird’s wings are present for support and propulsion.

The two theories of flight in birds are; the “ground-up” hypothesis based on running birds with primitive wings to snare insects, the “trees-down” hypothesis has birds passing through tree, climbing, leaping, parachuting, gliding and finally powered flight. The Lizards wings support the “tree-down” theory, because it glides down from a tree when it wants to avoid predator. Basalisk lizard: The basilisk lizard is able to walk on water because its feet have a large surface area that breaks the surface tension of the water.

The behavior evolved in the basalisk lizard as way of escaping predators, (anti-predatory behavior) especially land predators. Because they are vulnerable. Two-headed Snake: The evolutionary pressures may be predators attacking the snake, especially from behind, so the snake developed a way of distracting predators with its head and with its tail. It can be advantageous to the snake because it is going to reduce the risk of getting harm by predators. An example of another animal is the earthworm.

Snake Eating: The snakes jaw bone spread apart and it starts eating the squirrel from the head, so that its limbs can enter its mouth. Since the snake lives in the bush, and it’s a predator to other animals which are even larger than it, this mechanism is the best way for it feed on its prey. Alligator Predation: It’s a technique used by the young alligator to catch unsuspecting preys. The alligator is posed like a stature inside the water and waiting for an unsuspecting prey to catch.

The alligator is selected for this because it has the ability to pose like a stature without being noticed by the other animals. The Birds Convergent Evolution: Convergent evolution could be said to be a process in which two different species of the same animals gradually evolve to display a similar physical features. In the clip, the bird developed a long beak that can fit into a plants corolla for nectar, because of the kind of environment the bird is found, it gradually developed this kind of beak. The other bird in Madagascar also developed a ling beak for collecting nectar.

Finches Habitat Influence: The adaptive radiation that occurred in the finches was that there was diversity in them, although they all descended from a common ancestor which had medium sized beaks. But over time, island with small seeds were selected with birds with narrow beaks, while island with large beaks were selected for birds with large beaks. Finches Natural Selection: The speciation that occurred in the finches was when some of them were not able to pick up large seeds in the island and eventually died, but others with a beak quit longer than theirs were able to pick the larger seeds and so they did not die.

They passed this trait to their offspring. The new off springs had larger beaks that enabled them to adapt to the environment Pollinators: Co-evolution is the process where two or more species live together as a result of ecological relationships. In the clip, the birds and the bees helps pollinate the flours. The plants rely on the animals to reproduce, while the animals rely on the plant for food. Bird-Water Buffalo Mutualism: Mutualism is a relationship between two or more organisms that is beneficial to both of them. It benefits the egrets because they eat from the body of the tick, and the tick also gets cleaned.

Some birds can also exhibit such relationship with sheep’s in Yola. The Mammals Dolphin Behavior: The potential care shown in the clip is the mother feeding the baby dolphins with milk. The form of communication is the voice of the dolphins in the water. The adaptive significant of the communication is that the dolphins are able to warn themselves of impending danger. Manatee Population Threats: The manatees are declining because of their size; that is they are being hunted for food and because of the pollution of the water.

If people are stopped from polluting the water, and people are discouraged from hunting them, it can be reversed. Bat Territoriality: Their Skeleton is designed that way, because it enables them to hop, walk and fight. Meerkat Warning Calls: They behave differently because one of the calls was the call of an eagle, which is one of the cat’s most fared enemies, which happens to be a predator. They responded to the other call because they believed there was a prey around. The benefit of social living is that they warn themselves of impending danger, as well as coming together to eat.
