Reef lobsters, Enoplometopus, are a genus of small lobsters that live on reefs in the Indo-Pacific, Caribbean and warmer parts of the east Atlantic Ocean.
Species of Enoplometopus occur from coral reefs at depths of less than 1 metre (3 ft 3 in) to rocky reefs at depths of 300 m (980 ft). They are brightly coloured, with stripes, rings, or spots. They are typically mainly red, orange, purplish and white. Reef lobsters are small (depending on species, up to 10–13 centimetres or 4–5 inches), nocturnal (spending the day in caves or crevices), and very timid.The species can be distinguished by their colouration and morphology. source
