A coelenterate (cnidaria) of the family Hylocercidae in the class Anthozoa (illustration). It is also known by other names such as Horn coral, Black coral, and Mayoke coral. The names Horn coral and Black coral come from the hard, black bony shaft, and Mayoke coral comes from the fact that amulets made from the bony shaft were used as talismans to ward off evil in Europe long ago. It is widely distributed from central Honshu southward, and grows on rocky reefs at depths of 10m or more. It forms tree-like colonies that are usually around 50cm tall, but can sometimes reach heights of 2-3m. It forms colonies by sending out numerous feather-like branches that spread out in a single plane diagonally upward from a single trunk.

花虫綱ウミカラマツ科の腔腸動物(刺胞動物)(イラスト)。ツノサンゴ,クロサンゴ,マヨケサンゴなどの別名がある。ツノサンゴ,クロサンゴの名は硬くて黒い骨軸から由来し,マヨケサンゴは昔ヨーロッパで骨軸からつくった御守が魔よけとして使われたことによる。本州中部以南に広く分布し,水深10m以深の岩礁に着生する。ふつう高さ50cm内外の樹状の群体をつくるが,ときには2~3mの高さになるものもある。1本の幹から斜め上方に向けて一平面上に広がった羽状の枝を多数だして群体をつくる。
