There are several animals that fit that description: alligators, crocodiles, and gharials.
A crocodile and an alligator can swim underwater, walk on land and have big bites.
Aligator
The biggest animal on land is the Elephant AND The biggest animal in water is the Blue Whale
Some type of penguin
a duck is a land animal, but you'd probably mainly see them in water because they are fond of water and there pretty good swimmers.
A penguin is not a land animal. This animal can swim and dive in water. they catch their food in water too.
Yes they can. The opening to their lungs is in the form of a muscular tube that can be closed when required. Even snakes that are normally land-dwellers have the ability to bite while in water.

A land animal.
A seal's first line of defense is flight. They have a physiological defense mechanism which is an outer coating of several inches of blubber that make it difficult to bite into a seal to kill it. It takes a large animal, so they have few predators. Because they can be on land and in the water, they can jump into the water and out maneuver land predators and can return to land when attacked by water based predators.
aligator
No. They are animals that live on land. They enter the water to feed on acquatic plants but they do not live in water. If they try to do so, they will drown. However, capybara's mate under water.
