Paraclinus grandicomis, the horned blenny, is a perciform marine species of labrisomid blenny native to reefs of the Atlantic Ocean and the Caribbean Sea.[2] It is a benthic fish, so it cruises along above the sandy or rocky seabed and forages for crustaceans.[3]
The horned blenny can be commonly found in shallow waters, between 0 and 3 meters, inhabiting sponges, corals, and sea anemones.[4][5] Its habitat choice relies on the abundance of food and shelter from predators, which is why it can be observed occupying seabed clams, oysters, shells, and submerged vegetation such as mangroves and seagrass.[4]
Geographic distribution
The Paraclinus grandicomis inhabits tropical waters that range from southern Florida through the Lesser Antilles.[2] This species dwells in tropical (10–23N) and subtropical (23–35N) climate zones.[3]
Physical description
The horned blenny is a brown-colored fish covered in pale mottling all over its body and head.[3] Dorsal, anal, and tail fins have dark brown bases and pale or clear edges.[3] This species is characterized by having elongated snouts that are blunt at the end and a singular large horn called the maxillary bone branching from their heads; additionally, thin strands of cirrus cover the nostrils and line its stalk from eyes to dorsal fin.[3] The blenny's spine is composed of 34–35 small vertebrae,[6] giving it a maximum length of only four centimeters.[2]
Ecology
The horned blenny, as well as some other Caribbean reef fishes, have developed behavioral and physiological adaptations that make them immune to stings of sea anemones. The acclimation process can take several minutes to several hours of being stung repeatedly by an anemone tentacle to build resistance.[5]
