The broadnose sevengill shark is one of the signature species of False Bay's kelp ecosystem, a large, slow-moving predator that patrols the reef bottom in water as shallow as 5 metres. Unlike most shark species, sevengills do not flee from divers and will approach closely out of curiosity, their seven distinctive gill slits and broad heads making them unmistakable. Their presence in shallow, accessible water makes Miller's Point one of the few places in the world where open-water divers can reliably observe this ancient shark family at close range.

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.
