Adalaria proxima
''Adalaria proxima'' is a species of sea slug, a dorid nudibranch, a shell-less marine gastropod molluscs in the family Onchidorididae. This species is found in the northeastern and northwestern parts of the Atlantic Ocean. It is also known from the northeastern Pacific Ocean.
==Description==
''Adalaria proxima'' is oval in shape and grows to a length of about . The head has a flattened piece of tissue above the mouth. The mantle is covered with club-shaped tubercles with pointed ends which are stiffened with calcareous spicules (spine-like structures). The body is a yellowish-orange colour, but is often quite a pale shade, especially in the northernmost part of the animal's range. The blunt-ended rhinophores (sensory tentacles on the head) are often darker in colour than the rest of the animal, and each bears up to nineteen thin plates. The anal papilla is surrounded by a ring of about twelve feathery gills.〔 This species can be confused with ''Onchidoris muricata'', but that species is usually smaller and paler and has rhinophores that have tips which are more pointed.〔
