Is a lobster an invertebrate or a vertebrate?

A lobster is an invertebrate and not a vertebrate. Lobsters do not have backbones or a spine, they have a carapace for rigidity.

The carapace is a hard exoskeleton, or protective shell.

Some people refer to them broadly as shellfish, but a lobster is a large crustacean.

We especially refer to them as shellfish when talking about cuisine. For example, we may say “I am cooking shellfish Saturday, why don’t you come over”.
