Pharaoh Cuttlefish

Sepia pharaonis

Sighting evidence at Dutch Bay Wall, Kalpitiya

The largest cuttlefish in the Indian Ocean reaches 50 cm along this wall, hunting fish and prawns with hypnotic chromatic displays that momentarily freeze prey. Males engage in spectacular colour-flashing competitions near the wall's sea-fan clusters — one side of the body signaling aggression to a rival while the other simultaneously displays courting colours to a female. Dutch Bay's sheltered conditions make cuttlefish encounters reliable on nearly every dive, in contrast to the more exposed sites where surge and current displace them.

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.
