Adaptation of Animals
Adaptation of Animals
A fish possesses gills and fins that allow it to live in water. The gills and fins are its adaptive structure. Adaptation is the ability of organisms to adjust to their environment. It is possible through the animals' adaptive structures or behaviors.
Adaptation to the Environment
Examples of animals that show adaptation to environment are as follows:
The shape of the dolphins' body is stream-like, so that it can move through water easily and smoothly.
Penguins are birds that are adapted to aquatic existence. Unlike
birds, structure are adapted for flying, the penguins forelimbs are short and flat flipper suitable for swimming.
B. Adaptation to Climate
Below are examples of animals that show adaptation to climate.
The flaps and appendages of whales enable it to conserve heat during the cold weather.
The rabbits' huge ears enable them to radiate excess heat in the body.
Turtles, toads and frogs dig themselves into the soil. Sometimes
they retreat to the cave. Snakes undergo a long sleep during winter or until the undesirable condition is over. This period of winter inactivity is called hibernation.
Mudfish burries itself in the dry mud and wait until the next rainy season comes. This period of summer inactivity is called extivation.
5. Animal in Foreign Land
These animals migrate when climate changes. An example is the seal. The seal travel as much as 2,800 km. across to escape winter. Several birds migrate during some parts of the year like spring and fall Migration is in the movement from one home to another. There are reasons that scientists give why birds migrate. They migrate due to climatic changes. Their food supply may be gone or they might be used to breed in other parts of the world. Some birds that live in the north fly south during winter.
C. Adaptation for Feeding
Certain insects have mouth parts or othermodified structures as adaptation for feeding.
Mosquitoes have long, slender tube-like mouth part called proboscis to enable female mosquitoes to suck blood and males to suck plant juices.
Aphids also have mouth tubes used for piercing and sucking juices from plant stems.
Butterflies have very long proboscis. These tubes unroll to sip nectar deep within the flowers.
Dragonfly nymph has a labium modified into a hinged structure. The labium unfolds to capture prey and puts it into its mouth.
