Aeolid nudibranchs are some of the most striking sea slugs found on Indo‑Pacific reefs, including the vibrant waters along Fiji’s north coast. Known for their bright coloration and the rows of cerata that line their back, these nudibranchs have a fascinating survival strategy: they feed on hydroids and anemones, then store the prey’s stinging cells in their cerata for protection. This process, called kleptocnidae, makes them one of the most unique predators on the reef. Despite their delicate appearance, aeolids play an important ecological role as specialized feeders, and their presence often indicates a healthy, biodiverse coral environment.

I recently presented a black-and-white image of an Aeolid Nudibranch. Here’s another perspective in color. I love its natural purple color.
Which image do you prefer color or black and white?
Let me know in the comments?
