Common Name: Unidentified Flabellina

Adult Size: 10 – 30 mm
Depth Range: 3 – 30 m
Biotope / Habitat: Found on coral reefs and rocky slopes, often on or near hydroids which serve as both habitat and food source
Diet: Specialized feeder on hydroids, using its radula to scrape and consume polyps, incorporating their stinging cells (nematocysts) for self-defense
Reproduction: Hermaphroditic; mates reciprocally, with eggs laid in delicate, spiral-shaped ribbons on hydroids or hard substrates
Fun Fact: Flabellina sp. is known for its stunning, elongated cerata and vibrant coloration, which warn predators of its potent chemical defenses.

This dazzling nudibranch features a slender, often brightly colored body adorned with long, tapering cerata that wave gently in the currents — a striking sight for divers and underwater photographers!
