The animal on the cover of Org Design for Design Orgs is a crimsontip longfin fish or coral devil (Plesiops coeruleolineatus). As its name suggests, the longfin fish has a long body that grows to between 8.5 and 10 centimeters. While its coloration varies, its body is usually black or brown with two dark stripes behind the eye. Its dorsal spines have orange or red tips with a bottom border of white, and the basal part of the dorsal fin has a blue stripe.
The crimsontip longfin can be found from the Red Sea and East Africa to the Samoa Islands, Oceania, and southern Japan. It can also be found as far south as Australia at Queensland. This species is described as “secretive” and lives in the shallow parts of outer reefs. It comes out at night, when it feeds on fish, gastropods, and small crustaceans.
