and Paracorallium genera can be found in abundance around the seamounts around Japan and China. Likewise, the corals of the genera Corallium are widespread along the Mediterranean and the neighboring Atlantic coasts and is primarily seen around the central and western basin. Whereas population tends to decrease in deeper water in the eastern basin and around the Canary Islands, southern Portugal and Cape Verde. The two places to date that have been reported to have high levels of species diversity and exploited populations are the Mediterranean Sea and the adjacent Atlantic, together with the Northern Pacific Ocean. Biological Behavior Feeding All polyps of the order Alcyonacea consists of tentacles and pinnules to capture food. The tentacles located on the coral lie in the same plane as the mesenteries, concave oral discs, but are bent slightly forward or backward. This orientation is beneficial in the feeding process as the tentacle(s) can enter what is known as the preparatory feeding position, giving rise to the raptorial manner of feeding observed in these corals. Once food is captured by the tentacles, it will flex toward the mouth, where the food will then be sucked into the pharynx. After the tentacle is free of the food particle, it will then be flexed outward and assume the preparatory feeding position again. In order to capture bigger prey like brine shrimp, several tentacles must repeat the raptorial manner of feeding in conjunction. Reproduction Within this family of the order Alconycea, also known as Octocorallia, two types of sexual reproduction strategies can be seen. One strategy involves the process where corals release both sperm and eggs into the water in mass quantities and fertilize, a process also known as broadcast spawning. The other involves fertilization in or on a maternal colony, in which embryos are incubated either internally or externally of the colony. Once fertilization takes place, the formation of a larval polyp known as a planula arises. This planula will then float around in the ocean for several days until it can attach to a hard surface and bud into a developing colony. These reproductive strategies may also change from location to location, as seen within the species of the Corallium genera C. rubrum. Within the Indo-Pacific Ocean, this species uses broadcast spawning to reproduce whereas the Mediterranean species releases planulae, a larval form of the coral. Reproductive behavior appears also differ with temperature with as
