The longsnout seahorse is the most commonly encountered seahorse species in the Caribbean and Dominica supports some of the healthiest populations in the Lesser Antilles. Males carry the young in a brood pouch for 14 to 28 days and give birth to miniature fully formed juveniles. At Scotts Head they are found anchored by their prehensile tails to gorgonians and sponges between 12 and 30 m depth.

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.
