Lancer stargazer – Kathetostoma albigutta

Kathetostoma albigutta, also known as the whitespotted stargazer, is a species of fish belonging to the family Uranoscopidae. This fascinating fish is characterized by its unique morphology and intriguing behavior.

Description & Characteristics

Kathetostoma albigutta is a relatively small fish, with a maximum recorded size of 28.0 cm. Its body is elongated and compressed laterally, giving it a distinctive shape. Its eyes are positioned on the top of its head, allowing it to observe its surroundings while partially buried in the sand. The fish’s most notable feature is its large, terminal mouth, which is armed with numerous sharp teeth. This specialized mouth allows Kathetostoma albigutta to ambush its prey with impressive efficiency.

Habitat and Occurrence

Kathetostoma albigutta is a demersal fish, meaning it lives on or near the bottom of the ocean floor. It is found in a wide range of depths, typically inhabiting waters between 40.0 and 385.0 meters. Kathetostoma albigutta prefers sandy or muddy bottoms, where it can effectively camouflage itself and wait for unsuspecting prey. It is a prevalent presence in the bathyal and abyssal marine zones, making it a significant component of these deep-sea ecosystems.

Taxonomy

The species Kathetostoma albigutta belongs to the Class: Teleostei, Order: Perciformes, and Family: Uranoscopidae. The Teleostei is a large and diverse group of ray-finned fishes, comprising over 20,000 species. The Perciformes is the largest order of fishes, including a wide variety of species, and is characterized by its spiny fins and often, a prominent dorsal fin. The Uranoscopidae, known as stargazers, are a family of perciform fishes with distinctive large, upward-facing mouths, a feature that gives them their common name.

Feeding

Kathetostoma albigutta is a carnivorous fish, feeding primarily on smaller fish, crustaceans, and other invertebrates. Its unique mouth structure allows it to efficiently ambush its prey. By burying itself in the sand, Kathetostoma albigutta waits patiently until its prey is within striking distance, then quickly snaps up its food. The fish’s sharp teeth ensure that its prey is firmly secured.
