The Blackedge Thicklip Wrasse, Blackeye Thicklip Wrasee, Half-and-half Thicklip, Half-and-half Wrasse, Half-half Thicklip, Thick-lipped Wrasse, Thicklip Wrasse, scientifically known as Hemigymnus melapterus, is a fascinating and colorful fish species found in various marine environments.
Description and Characteristics
The Hemigymnus melapterus is a distinctive wrasse species, recognizable for its unique color pattern. Adults of this species can grow up to a maximum size of 39.6 cm. The body of the Hemigymnus melapterus is typically a bright orange or reddish-orange, with a prominent black margin along its dorsal fin, hence the name “Blackedge Thicklip Wrasse.” This black margin extends to the upper lobe of the caudal fin, giving the fish its characteristic “half-and-half” appearance. The Hemigymnus melapterus also exhibits a dark, almost black eye, adding to its striking appearance. These wrasses are often found in both solitary and schooling behavior, adding to the diversity of their observed habits.
Habitat and Occurrence
The Hemigymnus melapterus is a common resident of coastal waters, particularly thriving in coral reefs, lagoons, ocean beaches, and seashores. They are often observed on reef flats, rubble floors, sandy sea floors, and seaward facing reefs. This adaptability allows the Hemigymnus melapterus to thrive in a range of depths, from the surface to a depth of 30 meters. This adaptability extends to various marine zones, including Subtidal, sublittoral, infralittoral, and deep zone of the oceans from the lower limit of the intertidal zone (intertidal) to the shelf edge at about 200 m water depth. neritic., making it a prevalent presence in these aquatic ecosystems.
Taxonomy
The Hemigymnus melapterus is classified within the Class: Teleostei, Order: Eupercaria incertae sedis, and Family: Labridae. This classification reflects its evolutionary relationships with other fish species and its distinct characteristics.
Feeding
The Hemigymnus melapterus is a carnivore, primarily feeding on a diet of clams, crustaceans, invertebrates, snails, and worms. Their strong jaws and teeth are well-suited for crushing and consuming these prey items, allowing them to efficiently navigate their diverse diet.
