The 22 Most Outstanding Saltwater Animals

There are more than 200 saltwater animals. These have evolved to suit a marine environment. They can have fin-like appendages, hydrodynamic body shapes, and different methods of dealing with extreme temperature changes..

The ocean or salt water provides a habitat for a wide variety of animals, including mammals and cetaceans. Saltwater animals obtain oxygen through their gills. Some have adapted to survive in the deepest soils of the ocean, where the pressure can be unbearable for other organisms..

The aquatic environment does not allow the absorption of light; As a result, many marine mammals have poor eyesight and have evolved to use echolocation..

List of saltwater animals

1- Crab

It is a crustacean similar to shrimp and lobsters; there are more than 6700 species. Most of these species are found in shallower waters, as they tend to inhabit coral reefs and coastal stones..

Crabs have thick armor that protects them from immediate danger; they also have two clamps that allow them to grab their prey.

2- Angelfish

There are more than 100 species that roam the waters of the southern hemisphere. There are two main types of angelfish: freshwater ones, which live in South America; and those who inhabit the oceans.

The saltwater angelfish can grow up to 12 inches and is known for the very colorful markings on its body. Their colors vary according to the species.

The harbor seal lives in cold waters around the world. Many species inhabit the waters of the northern hemisphere.

They are often found in coastal waters, where there is an abundance of food and fewer predators.

It is believed that there are more than 30 species of seals. These animals are closely related to sea lions and walruses.

5- Common dolphin

Common dolphins are found in deep salty waters; some dolphin populations may be present in the same location, while others appear to have a migratory pattern.

Dolphins travel in groups of 10 to 50 members and frequently gather in flocks of 100 to 200 individuals. These animals are among the fastest in the sea, and they are very active and playful.

6- blue whale

It is the largest animal on the planet, as it can weigh up to 200 tons. It is also the loudest animal, since it can sound louder than an airplane.

This is because they provide excellent places for animals to hide from predators and breed..
