Invertebrates have no backbone or spinal column.

Two invertebrates prepared for battle.

It feels like carbohydrates are toxic like the toxins contained in invertebrates in the world's oceans.

Insects are invertebrates.

Insects are the only invertebrates that can fly.

Pseudo-nitzschia produces a neurotoxin called domoic acid, which can build up in shellfish, other invertebrates, and fish. This can lead to illness and death in a variety of birds and mammals that consume them.

Most animals with tentacles are invertebrates.

Usually found in or near kelp forests, sea otters dine on invertebrates such as snails, crabs, octopuses, urchins, and abalone.

Two hundred million years after the solar collision innumerable species of sub-human grazers with long sheep-like muzzles, ample molars, and almost ruminant digestive systems, were competing with one another on the polar continent. Upon these preyed the sub-human carnivora, of whom some were built for speed in the chase, others for stalking and a sudden spring. But since jumping was no easy matter on Neptune, the cat-like types were all minute. They preyed upon man's more rabbit-like and rat-like descendants, or on the carrion of the larger mammals, or on the lusty worms and beetles. These had sprung originally from vermin which had been transported accidentally from Venus. For of all the ancient Venerian fauna only man himself, a few insects and other invertebrates, and many kinds of micro-organisms, succeeded in colonizing Neptune. Of plants, many types had been artificially bred for the new world, and from these eventually arose a host of grasses, flowering plants, thick-trunked bushes, and novel sea-weeds. On this marine flora fed certain highly developed marine worms; and of these last, some in time became vertebrate, predatory, swift and fish-like. On these in turn man's own marine descendants preyed, whether as sub-human seals, or still more specialized subhuman porpoises.

On the rocks where the holdfasts secure kelp fronds to the bottom live many invertebrates including abalone, sea urchins and sea stars.
