noun
tentaculate
Zoological term for a group of aquatic invertebrates with tentacles, including tube worms, moss animals, and lampshells. Compare with 触手冠動物 (lophophorate).
See also: 触手冠動物
触手動物には、管虫や苔虫などが含まれる。
Tentaculates include tube worms, moss animals, and the like.
触手冠動物 (lophophorate) is a related but distinct group; 触手動物 is a broader, somewhat older term for tentacle-bearing invertebrates.
Compound of 触手 (tentacle) + 動物 (animal). The exact historical origin of the term is uncertain; it is a technical zoological coinage.
