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

The giant squid is the largest invertebrate, or animal without a backbone, ever to have lived on Earth! It can grow up to 60 feet long, so it's hard to believe that a giant squid has never been seen alive until 2006.

There are some animals, however, that are vertebrates that manage to get along just fine without having a bony skeleton. The best examples of this are cartilaginous fish, i.e. sharks, rays and ratfish. Instead of having a mineralized skeleton with bony tissue, their skeleton is composed of cartilage.

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.

Octopuses. When it comes to intelligence, vertebrates typically outside invertebrates. But octopuses prove you don't need a backbone to have a big brain. The octopus has a large brain and extensive nervous system.

Echinoderms are animals with spiny skin such as sea urchins, sea stars, and sand dollars. Snails, clams, oysters, and mussels are examples of mollusks. A mollusk has a soft body. Arthropods are animals with jointed legs such as spiders, insects, lobsters, and crabs.

They are called invertebrates.

vertebrate, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. They have backbones, from which they derive their name.

Many invertebrates use gills as a major means of gas exchange; a few, such as the pulmonate land snail, use lungs. Almost any thin-walled extension of the body surface that comes in contact with the environmental medium and across which gas exchange occurs can be viewed as a gill.

Is a jellyfish an invertebrate? ›

These simple invertebrates are members of the phylum Cnidaria, which includes creatures such as sea anemones, sea whips, and corals. Like all members of the phylum, the body parts of a jellyfish radiate from a central axis.

A snake. A snake can have 600 to 1800 bones, depending on the species.

Invertebrates are animals without a backbone or bony skeleton. They range in size from microscopic mites and almost invisible flies to giant squid with soccer-ball-size eyes. This is by far the largest group in the animal kingdom: 97 percent of all animals are invertebrates.

Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it. They obtain nutrients and oxygen directly from the water that they live . Q.

Complete answer:The largest living invertebrate is Architeuthis or Giant Atlantic Squid. It is the largest (55 feet) and heaviest (8 tonnes) invertebrate. They have the largest eyes. They belong to the phylum Mollusca.
