Alatinidae

Alatinidae is a family of marine fish in the order Perciformes. Commonly known as “flying gurnards” or “flying gurnardfishes,” they are distinguished by their elongated pectoral fins, which they use to “fly” through the water. Alatinidae consists of two genera, Alatichthys and Alatinae, comprising 11 species.

Characteristics

Flying gurnards are characterized by their elongated pectoral fins, which are often much longer than their bodies. These fins are supported by numerous, slender fin rays, allowing the fish to glide through the water. Their bodies are typically slender and streamlined, with a slightly compressed profile. They possess a large mouth, often with a protruding lower jaw. Their color patterns are typically muted, blending with the ocean floor. Other common characteristics include:

  • Large, forward-facing eyes
  • Lateral line system that is often incomplete
  • Small, scaly bodies
  • Two dorsal fins, the first of which is typically short and spiny
  • A single, soft-rayed anal fin
  • Small pelvic fins located close to the pectoral fins

Environment

Flying gurnards are primarily found in tropical and subtropical waters worldwide. They inhabit a wide range of marine environments, from shallow coastal waters to deeper offshore areas. They are often associated with sandy or muddy bottoms and may be found near coral reefs or seagrass beds. They are typically benthic, spending most of their time on or near the bottom, and are primarily nocturnal feeders.

Diet

Flying gurnards are carnivorous and feed primarily on small invertebrates, such as crustaceans, worms, and mollusks. Their elongated pectoral fins likely aid in their foraging activities, allowing them to sift through the substrate in search of prey.
