Welcome to Invertemania where you can find all sorts of information on invertebrates.
What is an invertebrate?
What is an invertebrate? An invertebrate is a creature without a backbone! Most people would refer to invertebrates as bugs or creepy crawlies, but there are actually many different types of invertebrates. For instance, molluscs, insects, cnidarians, myriapods, arachnids, echinoderms, and crustaceans. Wow! That’s a lot of different types of “creepy crawlies”!
Invertebrates make up about 95% of all animals on earth. Vertebrates (yep, you guessed it, creatures with backbones) make up only 5%. Beetles (an order of insect) alone make up roughly 25% of animal species.
Invertebrates can be found living in water or on land. The one you see me holding here is a Rainbow Stag Beetle named “Olivine”. He’s an invertebrate too! (And happy about it.)
Cnidarians are probably the most primitive of all invertebrates while molluscs are the most advanced.
You can find out more information about the invertebrates that I like on this site. Enjoy!
