The silky shark is one of the most abundant oceanic sharks in tropical seas and a reliable visitor to offshore pinnacles where they use the structure as a navigational landmark and feeding aggregation point. Named for the fine, almost smooth texture of their skin, silkies are curious and fast-moving. Their population has declined sharply due to bycatch in tuna long-line fisheries, making protected pockets like the Corn Islands increasingly important refugia.

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.
