Adaptation in animals

This document summarizes various adaptations that enable animals to survive. It discusses adaptations such as migration, hibernation, camouflage, mimicry and warning coloration that help animals find food and protect themselves from predators. It also outlines physiological adaptations like storing water or releasing antifreeze proteins that allow animals to survive in environments with limited water or cold temperatures. The document provides examples of different species that demonstrate each type of adaptation.

Every animal has adaptations, such as sense organs and teeth, that enable it to find and use food. Some use a wide variety of foods; others specialize. Features such as camouflage and protective shells enable them to cope with predators. •MIGRATION •HIBERNATION AND AESTIVATION •CAMOUFLAGE •MIMICRY •WARNING COLOURATION •ADAPTATION OF WATER SCARCITY IN ANIMALS •ADAPTATION TO COLD
1. MIGRATION :- Migration usually occurs before and after breeding seasons. During a breeding season, migratory animals are subjected to seasonal changes in environment and undergo physiological and anatomical changes. Collared Lemming Locust Locusts in Flight
HIBERNATION AND AESTIVATION:- The animal goes into a very deep sleep, and while it is asleep the metabolic rate slows down greatly and the core body temperature is substantially lowered. Any mammal that remains inactive for many weeks with a body temperature lower than normal may be said to be in hibernation Ground Squirrel Pocket Gopher Gopher Tortoise
MIMICRY:- Mimicry, physical or behavioural resemblance of one species to another to benefit itself or in effect, sometimes both species. By mimicking the colour bands and buzzing sounds of stinging bees Snake MimicryViceroy Mimicry
CAMOUFLAGE:- Camouflage , any evolved resemblance of an organism to its physical background causing it to be overlooked by potential predators or prey. Camouflage, or crypsis, commonly involves adaptations of size, shape, colour patterning and behaviour and is widespread in the animal kingdom, but less so in plants. Camouflage Coloration in Flatfish Praying Mantis Snowshoe Hare in Summer and Winter
WARNING COLOURATION:- DEVELOPMENT OF COLOURS IS CALLED WARNING COLOURATION. THEY CAN EASILY ESCAPE FROM PREDATORS. THEY HAVE SOME TOXINS ALSO Burrowing Frog
ADAPTATION OF WATER SCARCITY IN ANIMALS: THIS ANIMALS CONSERVE WATER. THEY WILL STORE WATER IN TISSUES, RELEASE SOLID URINE, SWEAT PORES ARE ABSENT ETC., CapybaraDromedary
ADAPTATION TO COLD:- COLD HARDENS THE SKIN OF THE ANIMALS AND THEY RELEASE ICE NUCLEATING PROTEIN INDUCES THE FORMATION OF ICE ON THE EXTERNAL SURFACE OF THE BODY AND CELLULAR FLUID AT LOW TEMPERATURE. Goby Polar Bear Northern Pike
