Animals that live in water are called aquatic animals. These animals have adapted to life in water and have specific characteristics and features that enable them to survive in their aquatic habitats.

Aquatic Animals:
Aquatic animals are found in a variety of water habitats such as oceans, seas, rivers, lakes, and ponds. They can be further classified into two categories:

1. Marine Animals:
- Marine animals live in saltwater environments such as oceans and seas.
- Examples of marine animals include fish, whales, dolphins, sharks, and sea turtles.
- These animals have special adaptations to survive in saltwater, such as gills for breathing, streamlined bodies for swimming, and blubber to keep warm in cold waters.

2. Freshwater Animals:
- Freshwater animals live in freshwater habitats such as rivers, lakes, and ponds.
- Examples of freshwater animals include frogs, turtles, ducks, and fish like trout and catfish.
- These animals have adaptations to survive in freshwater environments, such as webbed feet for swimming, lungs for breathing air, and specialized digestive systems to process nutrients from their diet.

Comparison to Other Options:
- Terrestrial animals (option a) refers to animals that live on land, not in water.
- Amphibians (option b) are a specific group of animals that can live both in water and on land. While some amphibians spend their early stages in water (like tadpoles), they eventually develop the ability to live on land as adults.
- Therefore, the correct answer is option c, aquatic animals, as it specifically refers to animals that live in water habitats.

Summary:
Aquatic animals are specifically adapted to live in water habitats. They can be found in both marine and freshwater environments. Animals that live in water are called aquatic animals, which distinguishes them from terrestrial animals (land-dwelling) and amphibians (able to live in both water and land).
