Plagiotremus
Plagiotremus is a genus of fish in the family Labridae, commonly known as “blenny wrasses” or “false morays”. These fish are found in tropical and subtropical waters worldwide. They are distinguished by their elongated, eel-like bodies, small mouths, and lack of scales. While often mistaken for morays, they are actually related to wrasses and share their characteristic protrusible lips.
Common Names
Members of the genus Plagiotremus are commonly known as "blenny wrasses" or "false morays" due to their resemblance to morays. They are also sometimes referred to as "cleaner wrasses" as some species are known to clean parasites off other fish.
Characteristics
Plagiotremus species share several distinctive characteristics:
- Elongated, eel-like body: They have a slender, serpentine body that resembles morays.
- Small mouth: Their mouths are relatively small compared to their body size.
- Lack of scales: Unlike most fish, blenny wrasses have no scales.
- Protrusible lips: Similar to wrasses, Plagiotremus species have thick, fleshy lips that can be extended to reach food.
- Dorsal fin: They possess a long dorsal fin running the length of their back.
- Anal fin: A long anal fin runs along their underside.
- Pectoral fins: Small pectoral fins are present near the head.
Environments
Plagiotremus species inhabit a variety of marine environments, typically in shallow, coastal areas. They are commonly found among coral reefs, rocky outcrops, and seagrass beds. They often conceal themselves within crevices, burrows, or under rocks, using their eel-like body to navigate tight spaces.
