Due to their distinctive markings and features, it is not a shock how Pinecone Fish, also known as Pineapple Fish, got their name. Pinecone fish belong to the Actinopterygii family of fish. Since their fins are supported by strong spines, this class is known as ray-finned fishes.
Pinecone fish can reach a maximum size of 7 inches, but most are usually between 4 and 5 inches long. The scales of the pinecone fish are black-outlined and light yellow in colour. They also have a short tail and a black lower jaw. On both sides of their heads, Pinecone have a light-producing gland. These are called photophores, and they produce a symbiotic bacteria that allows light to be visible. The light comes from luminescent bacteria, and its intent is unknown. It may be used to enhance vision, locate food, or interact with other fish. Besides their unusual bright scaly body and light producing organs, Pinecone fish fins are quite unique. To begin with, the fish has two dorsal fins on its tail. The first is made up of four to seven stout spines that alternately point to the left and right. The second dorsal fin consists of nine to twelve soft rays. Pinecone fish also have a very powerful, large spine with two to four small, soft rays on its pelvic fin, which is the first fin on the fish's underside.
