👉 The term "epizoan" is a type of organism that has an epidermis and a cuticle, similar to a crust or shell. They are also known as "epicycloids," which means "cuticle-like." The term "epizoan" comes from the Greek words "epi" (meaning "inside") and "zoon" (meaning "shell"). This type of organism is found on some marine organisms, such as sea stars.
