Question

Name two aquatic animals.

Answer 1

Hint: Aquatic animals live in the water as well as depend on it for their survival. There are different groups of aquatic animals consisting of fish, mammals such as whales, mollusks like sea snails, cnidarians such as jellyfish, along with crustaceans like crabs. They either live in fresh clear water or salt water and can be either said as vertebrates or invertebrates.

Complete answer:
The habitat that has water in its surrounding in which the organisms or animals survive and live is known as aquatic habitat. The organisms living in aquatic habitat are called aquatic organisms. For instance fishes, ducks, frogs, tortoises, etc.
> Fish
Fish are gill-bearing aquatic craniate animals which lack limbs with digits. They form a sister group to the tunicates, and together they form the olfactory. Adding to this definition they are the living hagfish, lampreys, as well as cartilaginous and bony fish along with various extinct related groups. Most fish are ectothermic and are cold-blooded, permitting their body temperatures to vary as ambient temperatures change, though some of them are large active swimmers like white shark as well as tuna can hold a higher core temperature.

> Sea snail
Sea snail is a usual for slow moving marine gastropod molluscs normally with visible external shells, like whelk or abalone. They share the taxonomic class Gastropoda with slugs, that are distinguished from snails primarily by the absence of a visible shell on their body. Determining whether some of the gastropods should be known as sea snails is not always smooth.

Note: Aquatic animals display mysterious behaviour as well as possess surprising powers than other species. Such powers allow some aquatic species to survive in challenging conditions like deep ocean. Such as Hagfish and platypus.
