The One-spot snapper, Lutjanus monostigma, is a species of snappers belonging Actinopterygii class, order Perciformes, Lutjanidae family. Lutjanus monostigma can reach a maximum length of 60 centimetres in males, with a common length of 50 centimetres. The dorsal profile of head is gently to moderately sloped and adults are silvery white with yellow fins. These dark eyed fishes have 10 dorsal spines, 3 anal spines and very large canine teeth.

These snappers are nocturnal and usually solitary or occur in small groups. They feed mainly on fishes and crustaceans, especially crabs. This species is widespread in the Indo-Pacific from East Africa to the Marquesas Islands, Line Islands, the Ryukyu Islands and Australia. Adults live in coral reef areas, usually close to caves and coral formations, at depths between 1 and 60 meters.

This fish is tipical of the Maldives Islands. The Maldives consists of 1,192 coral islands grouped in a double chain of 26 atolls, 26 along the north-south direction, spread over roughly 90,000 square kilometres (35,000 sq mi), making this one of the world’s most dispersed countries. The atolls are composed of live coral reefs and sand bars, situated atop a submarine ridge 960 kilometres (600 mi) long that rises abruptly from the depths of the Indian Ocean and runs north to south. dentice azzannatore maculato intotheblue.it

Only near the southern end of this natural coral barricade do two open passages permit safe ship navigation from one side of the Indian Ocean to the other through the territorial waters of Maldives. For administrative purposes, the Maldivian government organised these atolls into 21 administrative divisions. The largest island of Maldives is that of Gan, which belongs to Laamu Atoll or Hahdhummathi Maldives.
