Atlantic Bonito

Fast-moving schools of bonito sweep through the wreck site from June through September, pursuing baitfish schools that accumulate in the structure's lee. As a mid-sized tuna relative they occupy a critical role in the pelagic food web, bridging smaller schooling fish and the large apex predators — including bluefin tuna and blue sharks — that track them. Their speed and coordinated hunting behaviour creates dramatic feeding frenzies visible from the wreck deck.

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.
