Black prickleback – Xiphister atropurpureus

The Black Prickleback, scientifically known as Xiphister atropurpureus, is a fascinating marine fish species characterized by its distinctive appearance and unique habitat preferences. This fish, belonging to the family Stichaeidae, is a common sight in various marine environments, contributing significantly to the biodiversity of these ecosystems.

Description & Characteristics

The Black Prickleback, Xiphister atropurpureus, is a relatively small fish, typically reaching a maximum size of 30.5 cm. Its body is elongated and slender, with a compressed shape, giving it a somewhat eel-like appearance. The fish is distinguished by its dark coloration, often appearing almost black, which provides excellent camouflage in its preferred habitats.

Habitat and Occurrence

The Black Prickleback, Xiphister atropurpureus, demonstrates a preference for a specific range of depths, inhabiting waters between 8.0 and 12.0 meters. It is commonly found in the Subtidal, sublittoral, infralittoral, and deep zone of the oceans, particularly in the neritic zone, extending from the lower limit of the intertidal zone to the shelf edge at about 200 m water depth. This species thrives in these areas, where its camouflage coloration and body shape allow it to blend seamlessly with the rocky environments it calls home.

Taxonomy

The Black Prickleback, Xiphister atropurpureus, belongs to the Class: Teleostei, Order: Perciformes, and Family: Stichaeidae. This classification places it within a diverse group of fish characterized by their elongated bodies, often with spines and a tendency to inhabit coastal or benthic environments.

Feeding

The Black Prickleback, Xiphister atropurpureus, is an opportunistic feeder with a varied diet. It consumes a wide range of organisms, including algae, copepods, crustacean larvae, crustaceans, echinoderm larvae, invertebrates, mysis, shrimps, seaweed, worms, and zooplankton. This versatile feeding strategy allows it to adapt to the available food sources within its habitat, further contributing to its ecological success.
