Denise's pygmy seahorse

Hippocampus denise

Sighting evidence at Meno Wall, Gili Islands

Denise's pygmy seahorse reaches only 2.4 cm and lives exclusively on Muricella sea fans, its skin tubercles matching the fan's polyp texture so precisely that experienced guides use a pointer to indicate their position. On Meno Wall several fan colonies at 28 m to 35 m host resident individuals, making this one of the more reliable pygmy seahorse sites in Lombok Strait without a boat crossing to deeper Indo-Pacific reefs.

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.
