Galapagos Nudibranch

Sighting evidence at Punta Vicente Roca North, Isabela Island

The cold, nutrient-rich waters off Vicente Roca support an astonishing diversity of nudibranchs, including endemic Galapagos species rarely documented elsewhere in the Pacific. The black volcanic substrate provides stark contrast for these vividly colored gastropods, making them easier to spot for macro photographers. Their abundance reflects the high productivity of the Cromwell Current ecosystem, which supports an unusually complex cold-water invertebrate community within technically tropical latitudes.

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.
