Chromodoris Annae (Anna’s Magnificent Sea Slug)
Marine LifeChromodoris annae is one of the most visually striking nudibranchs in the Indo-Pacific. Its electric blue body creates a vivid contrast against the reef—making it a favorite subject for underwater photographers and divers.
[youtube https://www.youtube.com/watch?v=XJgXwrndmSg]The “right-sided” alignment: As simultaneous hermaphrodites, these nudibranchs align their right sides—where the genital openings sit just behind the rhinophores—to cross-fertilize each other at the same time, an efficient mutual reproductive strategy.
Species Identification
- BodyBrilliant blue coloration with a smooth, elongated form and a darker midline dash between the rhinophores.
- RhinophoresElongated, often orange to yellow, with a distinct darker dash between them on the mantle.
- GillsBranched orange to yellow gills arranged in a plume near the rear of the body.
- SizeTypically 40–60 mm in length.
- Common NamesAnna’s Magnificent Sea Slug, Chromodoris annae
The specific name annae is thought to honor a person named Anna, although the original description does not extensively document this dedication. Nevertheless, this species lives up to its reputation as a “magnificent” example among nudibranch enthusiasts.
The most distinctive characteristic of Chromodoris annae is its vibrant color pattern. It features a striking blue mantle with a dark midline stripe, flanked by bands of black, white, and orange to yellow. This pattern sets it apart from similar species such as Chromodoris lochi and Chromodoris willani.
The body exhibits a brilliant blue hue that can vary in intensity and may be adorned with tiny dark speckles. Bright orange to yellow gills and rhinophores enhance its high-contrast appearance, making this species particularly photogenic.
Puerto Galera is renowned as one of the premier destinations for nudibranch and macro diving in the Philippines. It boasts healthy reefs, diverse substrates, and dive sites that often yield dozens of species in a single excursion.
These nudibranchs are typically discovered on coral reefs and rocky substrates at depths ranging from approximately 15 to 100 feet, with the most common sightings occurring between 30 and 70 feet. They primarily feed on specific types of sponges, utilizing a radula—a ribbon-like feeding organ equipped with microscopic teeth—to scrape their prey.

Ever since my brother introduced me to sea slugs and marine flatworms, I have been captivated by their otherworldly presence and fluidity. What sea creature or plant is your fascination and why?

This small shell-less marine gastropod reaches roughly 2.5 cm in length. Its body is so intensely yellow that internal organs are visible through its flanks. Despite its delicate appearance, Gymnodoris subflava is an active predator — feeding on other nudibranchs and their egg masses.
Science SpotlightAposematic Warning Coloration
The bold yellow coloration of Gymnodoris subflava is widely thought to serve as an aposematic signal — a vivid warning to predators that the animal is unpalatable or potentially toxic. This strategy is common across many vividly colored nudibranch species and is one of the ocean’s most effective visual defenses.
Diving Dumaguete: A Nudibranch Hotspot
Encounters like this are part of what makes Dumaguete a globally recognized destination for nudibranch discovery. Marine biologists and dive enthusiasts travel from around the world to explore its diverse reef habitats. For underwater photographers, finding Gymnodoris subflava in the wild is nothing short of capturing pure underwater magic — and a testament to the health and richness of the Philippines’ coral ecosystems.

Close up work of a ceramic miniature sea dancer sculpture in progress. I wanted you to see the fine ridges, but if you look closely, you can even see my fingerprints 😁.
