Marine mammals play important ecological roles as both predator (many hunt for fish) and as prey, both for sharks and other, larger marine mammals. Humans have also long hunted marine mammals for food and fur.
Why are marine mammals so intelligent?
Whale and dolphin brains contain specialized brain cells called spindle neurons. These are associated with advanced abilities such as recognising, remembering, reasoning, communicating, perceiving, adapting to change, problem-solving and understanding. So it seems they are deep thinkers!
What are three characteristics of marine mammals?
What makes a marine mammal a marine mammal? They must meet the characteristics of all mammals — they breathe air through lungs, are warm-blooded, have hair (at some point during life), and produce milk to nurse their young — while also living most or all of their lives in or very near the ocean.
What is the study of marine mammals called?
A marine mammalogist is a scientist who specializes in the study of marine mammals. Marine mammalogy is a diverse field that often includes the study of animal behavior, communication, evolution, physiology, ecology, and zoology.

Who is the smartest marine animal?
Dolphins. Our first intelligent sea creature on our list probably isn’t a surprise—dolphins have long been recognized for their complex behavior. Their brains are larger than humans’, weighing in at 3.5 pounds (ours are only 2.9 pounds!).
What are the smartest marine mammals?
What are the 5 most intelligent marine animals?
- Sea Otter. Sea otters have not previously been fully documented but researchers are aware of how intelligent these marine mammals are.
What are the 5 main characteristics of marine mammals?
Marine mammals share several common characteristics among all mammals, such as the need to breathe air, being warm-blooded, having mammary glands that produce milk to feed their young, giving birth to live young (pregnancy/gestation periods) and in some cases having hair.
Why is a seal a mammal?
Seals and sea lions are semiaquatic mammals that are in a group called pinnipeds, meaning “fin-footed.” Walruses are also members of this group. Also, fur seals are so-named because they have thick fur that can trap air and help keep them warm. True seals have thin fur and use blubber for insulation.
Why is whale classified as mammal?
Whales are mammals because they give birth to live young, they have fur (although it is very sparse on their body), they have lungs and breath air and they provide milk for their young.
Is a shark a fish or a mammal?
Sharks are fish. They live in water, and use their gills to filter oxygen from the water. Sharks are a special type of fish known because their body is made out of cartilage instead of bones like other fish.
Is a penguin a mammal?
Like other birds, penguins have feathers. Penguins are fish, mammals, or amphibians because they live in water, on land, or both. Penguins are birds, even though they spend time on land and in water. Their motion in the water more closely resembles flying than the swimming motion used by other animals.
Which fish is a mammal?
There are 75 species of dolphins, whales, and porpoises living in the ocean. They are the only mammals, other than manatees, that spend their entire lives in the water.
