Dorid Nudibranch

Discodoris atromaculata

Sighting evidence at Žanjice Bay, Montenegro

The chocolate chip nudibranch is one of the most visually striking species in the Mediterranean, its white body patterned with large brown spots that mimic the toxic sponges it feeds on. Žanjice Bay's sponge gardens host year-round resident populations that graze slowly across the flat encrusting sponge colonies, leaving diagnostic feeding scars as they rasp through the sponge tissue. Encounters of 10 or more individuals in a single dive are not unusual during spring and autumn.

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.
