}} The slippery dick (Halichoeres bivittatus) is a species of wrasse native to shallow, tropical waters of the western Atlantic Ocean. DescriptionThe slippery dick wrasse is a small sized fish that can reach a maximum length of 35 cm.[2] It has a thin, elongate body with a terminal mouth, and its body coloration has three phases during its life:
Distribution and habitatThe slippery dick wrasse is widespread throughout the tropical and subtropical waters of the western Atlantic Ocean. It can be found from North Carolina and Bermuda to Brazil,[2] including the Gulf of Mexico and the Caribbean Sea area. The slippery dick wrasse is generally reef-associated at depths from {{convert|1|to|15|m|ft|abbr=on}}, but it's not very common in seagrass.[6][7] BiologyThis species feeds on benthic invertebrates, including crabs, small fishes, sea urchins and ophiuroids, polychaetes, and gastropods.[7][8] It is a protogynous hermaphrodite.[2] These fish form leks while breeding.[2] In North Carolina, 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. Status and threatsThis species is widespread and very common throughout much of its range in the Caribbean and Florida, although it is uncommon in northeastern Brazil. There are no major threats known to this species, and population trends are unknown. It is listed as Least Concern (LC) by the IUCN.[1] References1. ^1 Rocha, L., Francini, R. & Craig, M. (2010).
