aquatic animal is the annelids which are segmented worms. There are three different classes they are

polychaetes, oligochaetes, and hirudinea.[2]

It may breathe air or extract its oxygen from that dissolved

in water through specialised organs calledgills,or directly through its skin.Natural environmentsand

the animals that live in them can be categorized as aquatic (water) orterrestrial(land). Animals that

move readily from water to land and vice versa are referred to asamphibians.When animals live in

water, they have special adaptations to help them survive in an aquatic habitat. The more time the

animal spends in the water the quicker they adapt to their new habitat. There are numerous ways that

an aquatic animal can adapt to their habitat.

egument" is applied to any outer covering of an animal. Basically, it means the skin, although many

scientists describe the exoskeletonof arthropods as an integument. An exoskeleton is a coating of hard

protein type substances that entierly cover the outside of the animal. It provides a place for muscle

attachment. The vertebrate skeleton is internal and muscles attach from the outside. This permits larger

growth of the animal. Vertebrate animals have developed some very interesting excrescences, or

projections of the skin, some of which are well-known and easily oberved by most people. They are

scales, feathers, and hair. Although these characteristics are common among the most vertebrates, they

are not all that common in the animal world as a w

Amphibiansareectothermic,tetrapodvertebratesof theclassAmphibia. Modern amphibians are all

Lissamphibia.They inhabit a wide variety ofhabitatswith most species living withinterrestrial,fossorial,

arborealor freshwateraquaticecosystems.Amphibians typically start out aslarvaliving in water, but

some species have developed behavioural adaptations to bypass this. The young generally undergo

metamorphosisfrom larva with gills to an adult air-breathing form with lungs. Amphibians use their skin

as a secondary respiratory surface and some small terrestrialsalamandersandfrogslack lungs and rely

entirely on their skin. They are superficially similar toreptilesbut, along with mammals and birds,

reptiles areamniotesand do not require water bodies in which to breed. With their complexreproductive needs and permeable skins, amphibians are oftenecological indicatorsand in recent

decades there has been a dramaticdecline in amphibian populationsfor many species around the globe.
