Clearfin Lionfish

Clearfin lionfish hang motionless beneath cave overhangs in the dimlit interior, relying on their cryptic patterning and venomous spines rather than escape behaviour when approached. They are nocturnally active predators that use the cave's sheltered recesses as daytime resting sites, moving to the reef slope at dusk to ambush small reef fish. The cave supports unusually high densities of this species, likely because the sheltered environment limits predation on the lionfish juveniles.
