What is a nudibranch?

Answer 1

No. A Nudibranch is a mollusk, which is an invertebrate, related to marine snails that looks like a slug.

Invertebrate means lacking vertebrae (backbone).

All mammals are vertebrates, thus they have a backbone.

Answer 2

A nudibranch is not an echinoderm.

A crucial difference between and echinoderm and a nudibranch is that echinoderms (things such as sea cucumbers, starfish, and urchins) are deuterostoms while Nudibranchs (gastropods related to snails) are protostomes.

A protostome has: Spiral cleavage, blastopore becomes mouth and the nerve cord of the central nervous system is ventral

A deuterostome has: radial cleavage, blastopore does not become mouth(often becomes anus) , and Nerve cords of the central nervous system are not ventral.

There are many other differences but these are some of the basics.

As a human you are a deuterostome. So you are closer related to a Sea Cucumber than a Nudibranch!
