Stephanolepis

Stephanolepis is a genus of marine ray-finned fishes belonging to the family Monacanthidae, commonly known as filefishes. The genus encompasses a handful of species, primarily inhabiting the tropical and subtropical waters of the Indo-Pacific region. These fishes are distinguished by their elongated, laterally compressed bodies, often covered in spiky scales, and their prominent dorsal fins. Their coloration can vary widely, ranging from vibrant yellows and oranges to muted browns and grays, often with intricate patterns and markings.

Common Names

Depending on the species, Stephanolepis fish are known by various common names, including:

  • Filefishes
  • Triggerfishes
  • Leatherjackets
  • Unicornfishes

Characteristics

Stephanolepis species share several characteristic features:

  • Elongated Body: Their bodies are typically elongated and laterally compressed, giving them a streamlined appearance.
  • Spiky Scales: Their skin is covered in small, spiky scales, which provide protection from predators and contribute to their rough texture.
  • Dorsal Fin: They possess a prominent dorsal fin, often with a spiny first ray, which can be used for defense.
  • Mouth: Their mouths are small and often equipped with strong, beak-like teeth, well-suited for consuming invertebrates and algae.
  • Coloration: Coloration varies greatly between species, but often includes bright yellows, oranges, browns, and grays, sometimes with intricate patterns and markings.

Environments

Stephanolepis filefishes are typically found in shallow, inshore waters, often near coral reefs and rocky outcrops. They are generally solitary animals, but may occasionally form small groups, particularly during breeding seasons. These fishes are omnivorous, feeding on a diet that includes algae, invertebrates, and small fish.
