Animal and
aquatic insect
An aquatic animal
is naturally an animal that lives in water. It is not necessarily a fish
because some are mammals like the dolphin. The majority have gills to breathe
in the water, but this is not the rule, the whale has lungs and must go to the
surface to get some air.
Aquatic animals,
such as terrestrial animals, may be carnivorous or herbivorous depending on
their diet. The carnivore eats other aquatic animals and the herbivore can eat
algae for example. Some, like the turtle, will have an aquatic and terrestrial
life.
Both aquatic
animals and fish use gills to collect oxygen in the water to allow them to
breathe. The gills are not able to operate in the open air and the fish dies if
it is not in the water.

Many marine
animals, like the dolphin, have lungs and must breathe air. The whale has a
breathing hole on the top of the head to breathe when it comes in and out of
the water as it moves. Some may hold their breath for very long periods of time
before having to go back up to breathe like the turtle.

There are aquatic
insects that have to lay their eggs in the water and go from the larva to the
nymph and often become an adult fly capable of flying like the dragonfly.

There are
freshwater animals and saltwater aquatic animals. A freshwater animal can not
usually survive in salt water. The same thing for saltwater animals. Each
species has adapted to its environment and as many a dramatic change in their
environment can kill them and even eliminate the species.
To move, the fish
have fins arranged at different places of their body, but their tail is their
best means of propulsion. Other aquatic animals, such as some marine mammals,
have webbed feet that are used for swimming.
