Masked pufferfish

Arothron diadematus

Sighting evidence at Shaab Sharm, Fury Shoals

The masked pufferfish is a Red Sea endemic whose bold black mask and polka-dot pattern make it immediately recognisable grazing on algae and invertebrates across Shaab Sharm's rubble zones. When threatened it inflates its elastic stomach with water to become a near-spherical ball, making ingestion by a predator geometrically difficult. Their beak-like fused teeth are strong enough to bite through hard coral, and they leave characteristic semi-circular bite marks that are visible across the reef as evidence of their feeding activity.

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.
