Chemoreceptor

A chemoreceptor, also known as chemosensor, is a specialized sensory receptor cell which transduces (responds to) a chemical substance (endogenous or induced) and generates a biological signal.

Eumetazoa

Eumetazoa (Greek: εὖ, well + μετά, after + ζῷον, animal) or '''Diploblasts''', or Epitheliozoa, or Histozoa are a proposed basal animal clade as sister group of the Porifera.

Gene expression

Gene expression is the process by which information from a gene is used in the synthesis of a functional gene product.

Opisthobranchia

Opisthobranchs are a large and diverse group of specialized complex gastropods that used to be united in the subclass Opisthobranchia, but are no longer considered to represent a monophyletic grouping because it contains land snails and slugs, the Pulmonata.

Rhinophore

A rhinophore is one of a pair of chemosensory club-shaped, rod-shaped or ear-like structures which are the most prominent part of the external head anatomy in sea slugs, marine gastropod opisthobranch mollusks such as the nudibranchs (Nudibranchia), Sea Hares, (Aplysiomorpha) and sap-sucking sea slugs (Sacoglossa).
