Sea animals with photos and names list, description for children and adults

Marine animals are divided into 2 main categories: vertebrates and invertebrates. Vertebrates have backbones, invertebrates do not.

Oceanologists distinguish the main classes of marine animals, known as types:

  • jellyfish and polyps;
  • arthropods;
  • shellfish;
  • annelids;
  • chordates;
  • echinoderms.
  • All vertebrates are chordates, including: whales, sharks and dolphins, amphibians, reptiles and fish. Although there are millions of chordates in the seas, there are not as many vertebrates as there are invertebrates.

    There are 17 main groups of invertebrates that live in the sea, for example: crustaceans, hemichordates and others.
