How many classifications of invertebrates are there?

over 30 phyla
dedicated to invertebrates. Major invertebrate phyla that you should know include porifera, cnidaria, platyhelminthes, nematoda, mollusca, annelida, arthropoda, and echinodermata.
Is a jellyfish an invertebrate?
But despite their name, jellyfish aren't actually fish—
they're invertebrates
, or animals with no backbones. Jellyfish have tiny stinging cells in their tentacles to stun or paralyze their prey before they eat them. … But jellyfish don't purposely attack humans.
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.
What do invertebrates have in common?
Invertebrates share four common traits:
They are multicellular. All the cells have different responsibilities in keeping the animal alive. They
have no cell walls
, like all other animals. They reproduce by two reproductive cells, or gametes, coming together to produce a new organism of their species.
