The Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei) is a small, predatory fish species found in the tropical waters of the Indo-Pacific region. This species, named after William A. Gosline, an American ichthyologist, is known for its distinctive appearance and unique feeding habits.
Description & Characteristics
The Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei) can reach a maximum size of 6.4 centimeters. This fish is easily recognizable by its elongated, slender body, which is compressed laterally. The coloration varies, with a typically brown or reddish-brown base adorned with numerous white spots, creating a mottled appearance. The Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei) possesses a large, prominent mouth with sharp teeth, giving it a predatory look. These sharp teeth are well-suited for their primary feeding strategy of scraping scales and skin tissue off other fish.
Habitat and Occurrence
The Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei) is commonly found in shallow reef environments, typically at depths ranging from 1.0 to 15.0 meters. Its distribution spans across the tropical waters of the Indo-Pacific, with a preference for clear and well-lit coral reefs. This species is often observed residing among the crevices and ledges of these reefs, using these spaces for shelter and ambushing prey.
Taxonomy
The species Plagiotremus goslinei belongs to the Class: Teleostei, Order: Blenniiformes, and Family: Blenniidae. The Teleostei, also known as bony fishes, comprise the vast majority of fishes, representing a highly diverse group. The Blenniiformes, commonly referred to as blennies, encompass a wide variety of fishes with a unique combination of features, including elongated bodies, prominent eyes, and specialized fins. The Blenniidae, known as the combtooth blennies, are characterized by their comb-like teeth and their predominantly marine habitats.
Feeding
The Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei) is primarily a predatory fish, with a diet composed of mucus, scales and skin tissue from other fish, and occasionally zooplankton. It employs a unique feeding strategy, using its sharp teeth to scrape off the scales and skin tissue of other fish, often targeting larger species. This scavenging behavior contributes to the Biting Blenny, Gosline’s FangBlenny (Plagiotremus goslinei)’s survival and allows it to occupy a niche within the coral reef ecosystem.
