The Dussumier’s Blenny, Lance Blenny, scientifically known as Aspidontus dussumieri, is a small, slender fish belonging to the Blenniidae family. This species is characterized by its elongated body and distinctive pointed snout, which gives it a lance-like appearance. It is a common inhabitant of coral and rocky reefs, thriving in shallow waters, and is known for its diverse feeding habits.
Description & Characteristics
Aspidontus dussumieri typically reaches a maximum size of 12.0 cm. Its slender body is elongated, with a pointed snout that contributes to its “lance” common name. The Dussumier’s Blenny exhibits a vibrant coloration, showcasing hues of yellow, orange, and brown, often adorned with dark spots and stripes along its body.
Habitat and Occurrence
Aspidontus dussumieri primarily inhabits coral reefs and rocky reefs, exhibiting a preference for hard seabeds. This species is commonly found within the neritic zone, specifically in the subtidal, sublittoral, and infralittoral zones. This means it typically lives within the depths of 1.0 to 20.0 meters, making it a resident of the shallow, sunlit areas of the ocean.
Taxonomy
Aspidontus dussumieri belongs to the Class: Teleostei, Order: Blenniiformes, and Family: Blenniidae. The Teleostei class encompasses a vast majority of ray-finned fishes, while the Blenniiformes order characterizes blennies, known for their elongated bodies and distinctive features. The Blenniidae family, which includes the Dussumier’s Blenny, is a diverse group of fishes with various adaptations for life in coral reefs and rocky shorelines.
Distribution and Occurrence
The Dussumier’s Blenny, Lance Blenny, typically inhabits the neritic zone, encompassing the subtidal, sublittoral, and infralittoral zones. This makes it a prevalent presence in these aquatic ecosystems, thriving in depths from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. Its presence within these marine zones showcases its adaptability to diverse environments within this region.
Feeding
Aspidontus dussumieri is an opportunistic feeder, consuming a diverse diet that includes algae, brine shrimps, detritus, flakes, and mysis. Its varied diet reflects its adaptable nature and highlights its role in the marine ecosystem, contributing to the nutrient cycle.
