The Great Sandeel, scientifically known as Hyperoplus lanceolatus, is a slender, elongated fish commonly found in the coastal waters of the North Atlantic Ocean. This species, characterized by its streamlined body and pointed head, is a vital component of the marine ecosystem, serving as a food source for various larger fish and marine mammals.
Description & Characteristics
Hyperoplus lanceolatus is a relatively small fish, reaching a maximum length of 40.0 cm. Its body is remarkably slender and compressed laterally, tapering towards a pointed head. The mouth is slightly protrusible and equipped with small, sharp teeth. The dorsal fin is long and continuous, extending almost the entire length of the back. The anal fin is also elongated and positioned relatively close to the tail. The scales are small and embedded in the skin, giving the fish a smooth, almost eel-like appearance.
Habitat and Occurrence
The Great Sandeel is primarily an inhabitant of the neritic zone, the region of the ocean that extends from the shoreline to the edge of the continental shelf. This species is commonly found at depths ranging from 6.0 to 30.0 meters. It prefers sandy or muddy bottoms with a moderate current, where it can burrow into the substrate for protection and ambush prey.
Taxonomy
Hyperoplus lanceolatus belongs to the family Ammodytidae, a group of fish commonly known as sand eels. These fish are classified under the Order Perciformes, which encompasses a vast array of bony fishes, and the Class Teleostei, representing the most diverse group of ray-finned fishes.
Feeding
The Great Sandeel is a carnivorous fish that primarily feeds on small fish, fish larvae, and zooplankton. Its feeding habits are opportunistic, and it often uses its streamlined body to dart through the water column, catching prey by surprise.
