4. Aeolid Nudibranch (Trinchesia sp.)

Subject: An Aeolid nudibranch is crawling on a sandy bottom. This Trinchesia nudibranch (Trinchesia sp.) carries its defense mechanism on its back. The colourful cerata are packed with nematocysts, stinging cells of cnidarians that this nudibranchs has eaten and stored in cnidosacs, a powerful biological weapon to deter predators.

Technique: To highlight the little critter a vignette mask was added and the little yellow tips of the animal’s cerata were saturated. The crawling sound was also added to make the scene more convincing.
