Invertebrates
What is an invertebrate?
Scientists estimate that as many as 99% of all animal species are invertebrates. Invertebrates come in a variety of shapes and sizes, from microscopic organisms to giant squid. They can be found in virtually every habitat on earth, from oceans to rainforests. They may float, swim, fly, crawl, wiggle, or stay firmly attached to a surface (like sponges).
Invertebrates
The only thing all invertebrates have in common is their lack of a backbone. Here are five main groups of invertebrates.
-
Annelids
These are known as segmented worms, such as earthworms and leeches.
-
Arthropods
These include insects, spiders and crustaceans.
-
Cnidaria
These include jellies, anemones and coral.
-
Echinoderms
These include urchins and stars.

Mollusks
These include snails and octopuses.
