Trumpetfish are stealth predators of Caribbean reefs that use two remarkable hunting strategies: shadow hunting (hovering at a vertical angle above larger fish like parrotfish or surgeonfish to approach small prey concealed by the host's body) and colour-change ambush (switching from yellow to brown to mottled patterns to match the substrate). They hang motionless at the water surface to mimic floating sticks. Their elongated mouth generates a powerful vacuum strike that can engulf fish almost half their own body length. Abundant at Anses d'Arlet, they are frequently seen using green turtles and eagle rays as cover.

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.
