The Sea Bunny, a type of sea slug known scientifically as Jorunna parva, is a captivating creature that has gained popularity due to its cute and fuzzy appearance. It is found predominantly in the waters of the Indo-Pacific Ocean, these tiny marine gastropods bear a striking resemblance to a bunny rabbit.
Their charming looks have captured the interest of scientists and marine enthusiasts alike, leading to fascinating discoveries about their behavior and biology. Let’s dive in and learn more about the world of the Sea Bunny.
Appearance
The sea bunny is a species of marine gastropod mollusks. They are part of the family Discodorididae. Its fluffy bunny appearance is due to the large number of papillae that cover the surface area of its body, creating a white fur coat, along with black specks. They utilize these for various functions as they act as sensory organs.
The sea bunny is known to have different color variations. They have been seen in yellow, green, and white. The sea bunny is a small creature, averaging up to 1 centimeter in length.
One of its most distinctive features is a pair of rhinophores on its head, which resemble rabbit ears. These “ears” are sensory organs that detect chemicals in the water, helping the Sea Bunny find food and mates.
Did you know…
They have a tuft of feathery gills on their back which they use for breathing. This adds to their unique charm, making them look even more like a tiny underwater rabbit.
Habitat
Sea bunnies are mostly found in tropical waters, such as the Indian Ocean. They have been most recently recorded in locations such as Papua New Guinea, Réunion, Seychelles, and the Philippines.
Sea Bunnies prefer environments that provide camouflage and protection from predators. Their ability to blend into their surroundings helps them stay hidden while they feed on sponges. The diversity of habitats within the Indo-Pacific allows Sea Bunnies to adapt to different conditions, making them a fascinating part of marine ecosystems.
Diet
The main element of the sea bunny diet is sea sponges. They use a special structure called a radula, similar to a tiny ribbon of teeth, to scrape and eat sponge tissue. However, they are also known to eat algae, seagrass, and other small creatures, such as sea slugs or sea snails.
The toxins found in some sponges can be absorbed by them, helping them defend themselves from predators by making them less appealing or even harmful to eat.
Reproduction
All nudibranchs are hermaphrodites, they produce sperm and eggs but cannot fertilize themselves. They need potential mates for this to occur.
When two sea bunnies engage in mating, they stick to each other and complete a sperm exchange. These meetings are vital for them due to their relatively short lifespan. On average, a sea bunny only lives for a few 3-12 months.
Threats
By feeding on toxic sea sponges, they absorb the toxins and use them as protection, making them an unappealing or harmful choice for any animal that tries to eat them. This unique defense mechanism keeps them safe from predators.
Their main threats include overfishing, pollution, and habitat loss, particularly the degradation of coral reefs where they thrive. Like many other sea slug species, Sea Bunnies lack a protective shell in adulthood, leaving them vulnerable to issues such as ocean acidification and water contamination, which can significantly impact their survival.

Can sea bunnies change gender?
Sea bunnies possess both male and female sexual functions, making them hermaphrodites. This means that when they find a potential mate, both creatures provide eggs and sperm cells. Put simply, they are both genders at once.
How big are sea bunnies?
Sea bunnies tend to only reach 1 cm in length, making them relatively small in the oceanic ecosystem. However, their size is deceptive, as they are a fearsome prospect for any predators due to their toxicity.
