Seals are mammals! They possess all the things that make an animal a mammal. They are warm-blooded, they are vertebrates, they have fur, and most of all, the mothers feed their babies with milk expressed through mammary glands. Indeed, seal milk is some of the richest milk there is.

Is 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.

What sea animals have vertebrae?

Marine vertebrates are vertebrates that live in marine environments. These are the marine fish and the marine tetrapods (primarily seabirds, marine reptiles, and marine mammals). Vertebrates are a subphylum of chordates that have a vertebral column (backbone).

What is the purpose of a seal animal?

As one of the keystone species in marine ecosystems, seals help maintain a balance in the food web. Seals consume fish, squid, and crustaceans. Seals are also important food sources for larger predators like orcas, polar bears, and sharks.

Is a walrus a vertebrate?

Walruses are classified in the phylum Chordata, subphylum Vertebrata, class Mammalia, order Carnivora, suborder Pinnipedia, family Odobenidae.

Why are seals important?

Why are marine vertebrates important?

Marine organisms account for 15% of all life on earth. Approximately 750,000 species of confirmed invertebrates and 22,000 are found in our marine ecosystems. Marine vertebrates, although outnumbered in species and bio mass, have ecological importance and have a diverse range in habitat utilization.

What do all marine vertebrates have in common?

As chordates, vertebrates have the same common features: a notochord, a dorsal hollow nerve cord, pharyngeal slits, and a post-anal tail. Vertebrates are further differentiated from chordates by their vertebral column, which forms when their notochord develops into the column of bony vertebrae separated by discs.

Are seals vertebrates or invertebrates?
