"Sea bunnies retained their presence in the pantheon of kawaii animals, and now they are a common sight in souvenir shops and gashapon machines as well as making a few appearances in anime (Cosmic Princess Kaguya!) and video games (e.g., the mimic snow slugs in Honkai: Star Rail, though other nudibranch inspirations cannot be excluded).""

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.

Nembrotha kubaryana, also known as the variable neon slug or the dusky nembrotha, is a species of colorful sea slug, a dorid nudibranch, found in the tropical Western Indo-Pacific, it does not produce its own toxins, it feeds on colonial sea squirts (ascidians) and steals the toxin chemicals from its prey. It has warning colors which serve as deterring the predators but its eyes are simple, only capable of discerning light and dark, meaning it is likely blind to its own vibrant "beware" sign. It has noses on its head.

In the crystal-clear waters off Dumaguete, Philippines, a striking yellow nudibranch glows against coral and sand. Gymnodoris subflava captivates divers and photographers alike — a vivid emblem of the Philippines’ extraordinary reef biodiversity.
https://www.youtube.com/embed/yfiv4vdb5Tc Gymnodoris subflava nudibranch observed in Dumaguete, PhilippinesA Bright Yellow Carnivore
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.

Leaf sheep, a small sea slug native to the warm tropical waters of southern Japan, the Philippines, and Indonesia. Though they are animals, they indirectly perform photosynthesis in a process called #kleptoplasty, in which they absorb chloroplasts from the algae they eat. Their chemosensory rhinophores look remarkably like the ears of a sheep!

#SeaSlugs use daylight to show off their colors https://phys.org/news/2025-04-sea-slugs-daylight.html
Diel activity correlates with colour pattern morphology of heterobranch sea slugs https://besjournals.onlinelibrary.wiley.com/doi/10.1111/1365-2656.70036
"Rather than hiding from predators, the brightest and most patterned sea slugs are active during the day so their colors shine... They advertise their underlying defenses such as nasty chemicals or stinging cells with bold visual signals like brightly colored spots, thick stripes and enhanced body outlines"

12 Prized Sea Slugs: A Macro Cinematography Guide
This short underwater macro film brings together 12 sea slugs and nudibranchs filmed on scuba dives in Indonesia, the Philippines, Fiji, and St. Vincent. In about two minutes, the video highlights the extraordinary color, texture, and form that make sea slugs such compelling subjects for underwater cinematography. From tiny leaf-like sacoglossans to boldly patterned nudibranchs, each clip was selected to show how much variety exists across the world’s best macro diving destinations. Use the video and species timestamps below to identify each sea slug featured in the film and explore where each subject was filmed.
The Indo-Pacific Epicenter
In biodiversity hotspots like Lembeh, Anilao, and the Visayas, the density of nudibranch species can feel endless on a single dive. Many of the Indo-Pacific clips in this film were shot on black-sand “muck” sites, using a tripod or carefully braced fin tips to keep the camera rock-steady at high magnification. Subjects like Costasiella kuroshimae often measure just a few millimeters, so small movements or surges can easily ruin a shot.
Caribbean & South Pacific Gems
The Caribbean offers a different palette of “macro gems.” St. Vincent, featured prominently at the 1:25 mark, is a prized destination for divers seeking unique sea slugs that aren’t found in the Pacific. Similarly, Fiji provides stunning reef backdrops that make macro subjects pop against the vibrant soft corals.
Macro Video Techniques Used in This Film
Most clips in this sea slug video were filmed with a dedicated macro lens, small apertures for extra depth of field, and dual video lights to bring out the true colors underwater. I favored manual focus and slow, controlled moves so the viewer can study the nudibranch’s rhinophores, gills, and texture without distraction. For especially tiny subjects, I locked the focus and gently rocked the housing until the critical details popped into focus in the viewfinder.
