West Indian Sea Star

Oreaster reticulatus

Sighting evidence at Saona Island Reef, Bayahibe

West Indian sea stars congregate in remarkable densities in the seagrass beds adjacent to Saona's reef, acting as key grazers of detritus and microalgae on the sandy substrate. Their populations here are among the healthiest in the Dominican Republic, benefiting from reduced collection pressure within the national park.

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.
