Second Record of the Rare Triggerfish, Rhinecanthus abyssus Matsuura and Shiobara, 1989 (Actinopterygii, Tetraodontiformes, Balisitdae) from Sulawesi, Indonesia

摘要

The rare triggerfish, Rhinecanthus abyssus Matsuura and Shiobara, 1989, has been known only from the holotype and two paratypes collected from the Ryukyu Islands, Japan. A single specimen of this rare triggerfish was recently captured by a local fisherman off the northeastern corner of Sulawesi, Indonesia. The Sulawesi specimen of R. abyssus extends the distribution range 2,800 km southward.
