Reef lobsters (genus Enoplometopus) constitute a single family of small lobsters that live on coral reefs in tropical parts of the world's oceans. They are generally brightly coloured, with stripes or spots in shades of red, orange and pink; as a result, some species are gaining popularity in the aquarium trade.

Reef lobsters are distinguished from clawed lobsters (family Nephropidae) by having full claws (chelae) only on the first pair of pereiopods, the second and third pairs being only semi-chelate (where the last segment of the appendage can press against a short projection from the penultimate one). Males, unlike those of nephropoid lobsters, have an extra lobe on the second pleopod, which is assumed to have some function in reproduction. Clawed lobsters comprise a family (Nephropidae) of large marine crustaceans. ... A claw is a curved pointed growth found at the end of a toe or finger, or in arthropods, of the tarsus. ... Antennules Pereiopods Carapace Pleopods Uropods Telson The body of a decapod crustacean is made up of nineteen body segments grouped into two main body parts, the cephalothorax and the abdomen. ... An appendage is, in general, an external body part that projects from the body, or a natural prolongation or projection from a part of any organism. ... Antennules Pereiopods Carapace Pleopods Uropods Telson The body of a decapod crustacean is made up of nineteen body segments grouped into two main body parts, the cephalothorax and the abdomen. ... Reproduction is the biological process by which new individual organisms are produced. ...

Although there is no fossil record of reef lobsters, there is some evidence that they may be related to, or descended from, the extinct family Erymidae which lived from the late Triassic to the mid-Cretaceous. Ever since recorded history began, and probably before, people have found pieces of rock and other hard material with indentations from the remains of dead organisms. ... In biology and ecology, extinction is the ceasing of existence of a species or group of species. ... The Triassic is a geologic period that extends from about 245 to 202 million years ago (mya). ... The Cretaceous period is one of the major divisions of the geologic timescale, reaching from the end of the Jurassic period (about 135 mya) to the beginning of the Paleocene epoch of the Tertiary period (65 mya). ...
