What is the name of the fish in the picture below?
The Slippery Dick (Halichoers Bivittatus), is a small wrasse fish native to shallow, tropical waters of the Western Atlantic Ocean that can reach a maximum length of 35 cm (13.7 in). It has a thin, elongated body with a terminal mouth, and its body coloration has three phases during its life.
The first phase known as the terminal phase is when the fish becomes a male, so the body coloration turns to green with two longitudinal dark stripes. The head and tail are covered with pink lines; it has a small black dot up to the pectoral fin.
The second phase of the fish is when the juvenile becomes a female. The background body coloration is mainly whitish with pink shade, and the sides have two dark longitudinal stripes. The median one is usually black extending from the snout and via the eye to the base of the tail.
The last phase known as the juvenile phase. The body is usually whitish, still with the two longitudinal stripes and the spot up to the pectoral fin.
It is a protogynous hermaphrodite. Males defend temporary territories, with peak spawning in May and June. Pair spawning typically occurs between females and terminal phase males; initial phase males occasionally try to insert themselves into the spawning event.
Slippery Dick fish feeds on benthic invertebrates, including crabs, small fishes and sea urchins. This species is widespread and very common throughout much of its range in the Caribbean and Florida. There are no major threats known to this species.
