Dermatoplepis dermatolepis has a wide range that covers mostl of the Eastern Central Pacific and the Southeast Pacific. The most northern area that this fish extends into is the Gulf of California, USA, where it is very rare. The most southern country where the species is found is Ecuador. This fish is most abundant in the Revillagigedo islands. It is also found offshore of the following countries/islands: Bahia Magdalena, Galapagos islands, Cocos island, Clipperton island, Columbia, Costa Rica, Ecuador, El Salvador, Guatemala, Honduras, Mexico, Nicaragua, Panama, Peru, and USA. (Beller, 2000; Heemstra and Randall, 1993; Moore, 1991; "Marine Life Encyclopedia", 2004)
Leather bass live in reef areas with a depth between 4 to 40 m in the subtropics (35° N to 7°S). Leather bass inhabit rocky reefs and areas near the base of rocky faces. Juveniles are vulnerable to larger predators and will often times seek shelter in the spines of sea urchins. (Heemstra and Randall, 1993)
Adult leather bass have a distinctive color pattern of white markings on the head, body and fins along with small dark spots on a gray to olive brown background. On some fish, there are occasionally several dark bars running from top to bottom on the fish. Juvenile leather bass have black and white bands along their bodies, which help them integrate with the spines of the urchins they live in. Adults are about a meter long and can weigh up to 12.5 kg. Females are larger than males. (Beller, 2000; Moore, 1991; "Marine Life Encyclopedia", 2004)
Leather bass can change sex; some females change into males and become larger than individuals born as males. (Beller, 2000)
Leather bass assemble at dusk to mate. They locate a spot high on the reef, and then gather by the hundreds to spawn. The males and females pair off and hurry towards the surface, releasing a cloud of eggs and sperm. ("PBS Online", 2004)
The parents of juvenile leather bass have no parental investment. The only thing that the parents do is to mate and release a cloud of eggs and sperm. (Beller, 2000)
Leather bass are expected to live in the wild for approximately 24 years, maximum. (Heemstra and Randall, 1993)
Leather bass are social species that live within a large group. They are able to move about but usually stay in one general area, around coral reefs. Juveniles hide within the spines of sea urchins for protection. (Heemstra and Randall, 1993)
Their home range is specifically found around coral reefs within the Neotropical Pacific ocean. (Heemstra and Randall, 1993)
There was no information found on communication and perception on.
Leather bass can be found hovering above rocky reefs during the day searching for food. They feed on small benthic fishes that are disturbed when foraging grazers come to feed in an area. Occasionally, they feed on crustaceans, crabs, and shrimp nekton. (Heemstra and Randall, 1993; "PBS Online", 2004)
The only known predators of the leather bass are hunting macrofauna. (Heemstra and Randall, 1993)
Humans benefit from leather bass in that these fish provide minor commercial fisheries and gamefish for sportsman. (Heemstra and Randall, 1993)
There are no known adverse affects ofon humans.
The leather bass is in no immediate danger of being endangered. Therefore, it has no special status.

More specifically refers to a group of organisms in which members act as specialized subunits (a continuous, modular society) - as in clonal organisms.

structure produced by the calcium carbonate skeletons of coral polyps (Class Anthozoa). Coral reefs are found in warm, shallow oceans with low nutrient availability. They form the basis for rich communities of other invertebrates, plants, fish, and protists. The polyps live only on the reef surface. Because they depend on symbiotic photosynthetic algae, zooxanthellae, they cannot live where light does not penetrate.
