If you go to the octopus, and if you're not too squeamish, dissect it. You'll find that it has a camera eye which is remarkable similar to our own. And yet we know that the octopus belongs to an invertebrate group called cephalopod mulluses, evolutionarily very distant indeed from the chordates to which we belong.

Water is commonly regarded as the 'solvent of life,' since our bodies are 70% water. All other vertebrates, invertebrates, microbes, and plants are also primarily water. The organization of water within biological compartments is fundamental to life, and the aquaporins serve as the plumbing systems for cells.

I was thinking about what would it be, what would the characters be like, and it just suddenly dawned on me that, hey, nobody is doing an underseas show. So I started drawing these weird invertebrate animals, various characters like crawfish and starfish and squids and sponge.

The flesh-eating cockroaches and venomous centipedes in the Gomantong cave in Borneo were pretty unsavoury. They turn the floor of the cave, which is itself the world's largest pile of bird and bat poo, into a seething mass of invertebrate horror!

When you get into the whole field of exploring, probably 90 percent of the kinds of organisms, plants, animals and especially microorganisms and tiny invertebrate animals are unknown. Then you realize that we live on a relatively unexplored plan.

I have thought for a long time that one day, if I finally got to deserve it, I would love to write about the minds of invertebrates.

American Writer

The term often appears in scientific contexts, biology classes, and nature documentaries.

Biological Emphasis

While many invertebrates are tiny, the term includes large animals like squids too.

Not Just Small

Invertebrates make up the majority of animal species, showing incredible diversity.

The adjective form is often used in academic writing and scientific classification.

Scientific Usage

When describing an animal, choose either 'invertebrate' or 'vertebrate'—not both.

Avoiding Redundancy

Using 'invertebrate' helps to precisely categorize animals in educational and research texts.

Precision in Writing

 So a fungi species like this one. will come in and soften the wood, and then you get things like invertebrates coming in and breaking down that organic matter further. I just love things like this. You can so easily just walk past and never even set your eyes on them. But as creepy and as weird looking as they are, they're so important to the environment.

 Young icefish hide in small ice holes to avoid predators, while a variety of invertebrates, like jellyfish and siphonophores, congregate in the area. Many of them come to feed on krill, tiny shrimp-like creatures. Snow petrels nest on the icebergs and feed on the sea life nearby.
