We saw this Gosline’s Fang Blenny earlier this month at Mahukona.
When approached, these irresistible little guys back into worm snail holes in the coral and stick their heads out to observe and wait for the intruder to leave. Confident once in their refuge, they allow very close approach. They’re tiny—the head is smaller than the end of a pinky finger. (More about worm snails in a later post.)
