Overview
The Tokara habu is one of the least widespread habu species, confined to a handful of small islands in the Tokara group between Kyushu and Amami Oshima. Its restricted range makes it a species of conservation interest.
Like other habus, it fills the role of a nocturnal ambush predator within its island ecosystem.
