Water is a challenging environment for animals, and many species have adapted to swim and survive in aquatic habitats. In this article, we’ll look at 20 animals that are some of the most skilled swimmers in the animal kingdom.
#1. The Dolphin
Dolphins are a highly intelligent and social mammal found in oceans around the world. They are known for their speed, agility, and endurance in the water, as well as their complex communication and social behaviors.
Dolphins swim by moving their tail fin, or fluke, up and down to propel themselves through the water. They also use their pectoral fins, or flippers, for steering and maneuverability. They can reach speeds of up to 18 miles per hour and can swim for hours without getting tired.
Dolphins are also able to hold their breath for extended periods of time, allowing them to dive to great depths in search of food. Some species, such as the bottlenose dolphin, have been observed using tools, such as sea sponges, to forage for food on the ocean floor.
#2. The Shark
Sharks are a diverse group of fish found in oceans around the world. They are known for their speed, strength, and endurance in the water, as well as their highly developed senses, such as their sense of smell, which allows them to detect prey from long distances.
Sharks swim by moving their tail fin, or caudal fin, side-to-side to propel themselves through the water. They also use their pectoral fins for steering and maneuverability. Some species, such as the great white shark and the mako shark, can swim at speeds of up to 60 miles per hour.
Sharks are also known for their highly developed senses, such as their lateral line, which allows them to detect vibrations in the water, and their ampullae of Lorenzini, which allow them to detect the electrical fields of their prey.
#3. The Salmon
Salmon are a group of fish found in cold-water rivers and oceans around the world. They are known for their stamina, strength, and ability to swim upstream to spawn.
Salmon swim by moving their tail fin, or caudal fin, side-to-side to propel themselves through the water. They also use their pectoral fins for steering and maneuverability. They are able to swim against strong currents and even waterfalls to reach their spawning grounds.
Salmon also have a highly developed sense of smell, which allows them to navigate back to their home stream even after spending years at sea. They also have a unique homing instinct, which leads them back to the same stream where they were born to spawn.
#4. The Platypus
The platypus is a semiaquatic mammal found in eastern Australia. It is known for its unique physical characteristics, such as its bill, which is similar to that of a duck, and its webbed feet, which are used for swimming.
Platypuses swim by moving their hind legs and webbed feet up and down to propel themselves through the water. They also use their tail as a rudder for steering. They are able to swim for extended periods of time and can even sleep while swimming.
Platypuses are also able to hold their breath for extended periods of time, allowing them to dive to great depths in search of food. They primarily eat aquatic insects, crustaceans, and fish.
#5. The Eel
Eels are a group of fish found in freshwater and marine environments around the world. They are known for their elongated body shape, which allows them to swim through narrow spaces and burrow into the mud.
Eels swim by undulating their body, they have a long dorsal fin that runs almost the entire length of the body and helps them to swim. They also have a powerful tail that helps them to swim fast and move through the water.
Eels have the ability to migrate between freshwater and saltwater habitats, they are known to swim up rivers and even climb waterfalls to reach their breeding grounds. Some species of eel can even survive in brackish water environments.
#6. The Walrus
The walrus is a large marine mammal found in the Arctic Ocean. They are known for their large tusks, used for defense and foraging, and their tough, leathery skin, which protects them from the cold water and icy terrain.
Walrus swim by moving their large flippers up and down to propel themselves through the water. They can hold their breath for up to 30 minutes and dive to depths of more than 300 feet in search of food. They primarily eat clams, shrimp, and other crustaceans found on the ocean floor.

Otters can hold their breath for up to eight minutes, and they are able to close their ears and nostrils while diving to prevent water from entering.
Otters are known for their use of tools, such as rocks and shells, to crack open shellfish and other food. They are also known for their playfulness, often sliding down muddy banks and floating on their backs while holding hands with their family members to avoid drifting away from each other.
#8. The Stingray
Stingrays are a group of fish found in coastal waters and shallow seas around the world. They are known for their flat, diamond-shaped body, and the venomous spine on their tails, which they use for defense.
Stingrays swim by flapping their large pectoral fins, which are located on the sides of their body. They are able to swim long distances and change direction quickly and gracefully. Stingrays are able to bury themselves in the sand, to hide from predators and to ambush prey.
Stingrays are also known for their highly developed sense of smell and electroreception, which allows them to detect prey and predators from long distances.
