Scientific Name: Eubranchus sp.
Common Name: Unidentified Eubranchus nudibranch

Adult Size: 5 – 15 mm
Depth Range: 2 – 20 m
Biotope / Habitat: Found on shallow coral reefs and rocky outcrops, typically near hydroids, which it uses as both habitat and food
Diet: Specialized feeder on hydroids, using its radula to scrape and consume the delicate polyps
Reproduction: Hermaphroditic; mates reciprocally, with eggs laid in small, coiled ribbons attached to hydroids or algae
Fun Fact: Eubranchus sp.1 is easily overlooked due to its tiny size and transparent cerata, which help it blend perfectly with the hydroids it lives on.

This delicate nudibranch has a translucent body with fine, branching cerata that mimic the hydroids it grazes on. It’s a fascinating micro-predator for keen macro photographers and reef enthusiasts.
