Tawny nurse sharks rest motionless under coral overhangs during daylight hours, pumping water over their gills through buccal respiration rather than ram ventilation, which lets them remain completely still.

Nurse Shark is listed as a curated species here based on historical reports.

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.
