Psychedelic frogfish

Histiophryne psychedelica

Sighting evidence at Psychedelic Frogfish Slope

Histiophryne psychedelica was described in 2009 from specimens collected in Ambon Bay and has never been confirmed at any other location. It is unlike any other frogfish: the skin folds into a flattened body shape, it moves by bouncing off the seabed using jet pulses from its gill openings rather than walking on its pectoral fins, and its concentric white stripe pattern on an orange background is unique in the family. Scientists hypothesise the striped pattern may direct the gaze of threats away from its head. Its depth range is extremely shallow — most records are between 8 and 20 metres — and it appears to be genuinely endemic to Ambon Bay.

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.
