Short-nosed flyingfish – Cypselurus simus

Cypselurus simus, commonly known as the bluntnose flyingfish, is a species of marine fish belonging to the family Exocoetidae. Found in warm waters around the globe, these fish are known for their remarkable ability to leap from the water and glide through the air using their elongated pectoral fins.

Description & Characteristics

Cypselurus simus is a relatively small flyingfish, reaching a maximum size of 26.0 centimeters. They possess a distinct blunt snout, a characteristic that differentiates them from other flyingfish species. Their bodies are streamlined and covered in scales, allowing them to move efficiently through the water. Their elongated pectoral fins, which act as wings during flight, are remarkably large and provide the necessary lift for extended aerial glides.

Habitat and Occurrence

Cypselurus simus is primarily found in tropical and subtropical waters, typically inhabiting the epipelagic zone, which extends from the surface to a depth of 200 meters. This species is particularly common in the neritic zone, the area of the ocean that lies over the continental shelf. This suggests that Cypselurus simus is found in areas where the ocean floor is relatively shallow and close to the coastline. Their distribution is widespread, encompassing various marine zones, including the Indo-Pacific, the Atlantic Ocean, and the Mediterranean Sea.

Taxonomy

The species Cypselurus simus belongs to the Class: Teleostei, Order: Beloniformes, and Family: Exocoetidae. Teleostei, the largest infraclass of ray-finned fishes, is characterized by a bony skeleton, a swim bladder, and a variety of adaptations for life in aquatic environments. Beloniformes, the order to which Cypselurus simus belongs, is a diverse group of fish that includes needlefish, halfbeaks, and flyingfish. The Exocoetidae, or flyingfish family, are known for their remarkable ability to leap from the water and glide through the air using their elongated pectoral fins.

Feeding

Cypselurus simus is a carnivorous fish that feeds primarily on small crustaceans and plankton. They use their elongated pectoral fins to maneuver through the water and catch prey, often taking advantage of their ability to leap from the water to escape predators or capture food. Their diet is essential for maintaining their energy levels and facilitating their remarkable aerial displays.
