Blenny (Fang Blenny)

Meiacanthus grammistes

Sighting evidence at Izu Oceanic Park, Izu Peninsula

Fang blennies at IOP occupy holes and crevices in the rubble slope, darting out to feed on zooplankton before retreating with remarkable speed. They possess grooved venomous fangs — a trait so effective as a deterrent that several non-venomous species mimic their colouration for protection, creating a fascinating Batesian mimicry complex.

How is this calculated?

Sighting evidence is compiled from iNaturalist observation records within a set proximity radius, filtered for quality-grade observations. “Last confirmed” is the date of the most recent research-grade record. Record count covers a rolling 24-month window. Confidence reflects record count, recency, and consistency of seasonal signal.
