cnidarians
(such as sea jellies and corals), echinoderms (such as sea urchins and sea stars), mollusks (such as octopuses, snails, and clams), annelids (worms), and arthropods (such as insects, spiders, and lobsters).
What are three invertebrates that live in the sea?
The most familiar marine invertebrates include
crabs, corals, sea anemones, jellies, sea stars, sea urchins and shrimp
. Marine invertebrates such as the blue-ringed octopus, found off the coast of Australia and the western Pacific Ocean, are among the most deadly in the world.
What animal has the largest brain?

has the biggest brain of any animal species, weighing up to 20 pounds (7 to 9 kilograms). Larger brains don't necessarily make a smarter mammal.
Which marine invertebrate is considered the most intelligent?
The cephalopod class of mollusks are considered the most intelligent invertebrates and an important example of advanced cognitive evolution amongst animals in general.
Which animal have no bones?
Animals without backbones are called
invertebrates
. They range from well known animals such as jellyfish, corals, slugs, snails, mussels, octopuses, crabs, shrimps, spiders, butterflies and beetles to much less well known animals such as flatworms, tapeworms, siphunculids, sea-mats and ticks.
