Sand tiger sharks congregate around U-352 in unusually high numbers year-round, an aggregation that has made this wreck famous among wreck divers. They hover nearly motionless midwater using neutral buoyancy, swallowing air at the surface to adjust their swim bladder — a rare behaviour among sharks. Although intimidating in appearance with their rows of exposed teeth, they are generally docile and will circle divers closely at this site.

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.
