Juvenile pinnate batfish shelter near the wreck in their extraordinary juvenile guise — coal black body edged in vivid orange that mimics the toxic polyclad flatworm Pseudoceros ferrugineus so convincingly that predators avoid them entirely. This mimicry is abandoned completely as they mature into their adult silver form, representing one of the clearest examples of ontogenetic shifts in anti-predator strategy as different defenses become available with growth.

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.
