15 Fin-tastic Facts About The Little Dragonfish For Kids

Little dragonfish facts are about this species seen in the deep dark corners of the Indo-Pacific Ocean.

The little dragonfish (Eurypegasus draconis) is known by many different names such as short dragonfish and dragon sea moth. This fish is part of the family Pegasidae of the order Syngnathiformes. This family called Pegasidae consists of two genera, Eurypegasus and Pegasus. The traditional name of the family is taken from a creature from Greek mythology called Pegasus. This marine fish is a bottom dweller and is found in the deepest depth of oceanic water areas and sea. The little dragonfish habitat is found throughout the tropical waters of the Indo-Pacific, which includes the Red Sea. This fish has also been spotted in Australia, mainly north-western Western Australia and the Philippines. This is a small fish that sheds its skin in one piece. They can grow up to 3.93 in (10 cm), although species of 7 in (17.7 cm) have been seen too.

This odd-looking fish species is common in the Red Sea but rarely seen. These fishes are marked with a bony armor around the body that is extremely common in other species too. This species has a boring life and are usually seen feeding on small crustaceans and copepods among other things in deep sea areas. The fishes can camouflage themselves easily and this helps them be invisible to the world. The little dragonfish is identified by its flattened body, its long snouts to pick at small prey, and its large-sized wing-esque pectoral fins.

Dragon sea moth fish found in the Red Sea are great additions to any aquarium and mix extremely well with other species of seahorses, pipefishes, and gobies. However, these fishes are sold in millions each year for traditional medicine in Hong Kong and China alone.
