Range and habitat
Sea Bunnies inhabit Shallow reefs and rocky seabeds in the western Pacific and Indian Oceans, including Japan and the Philippines. Their preferred habitat includes shallow reefs and rocky seabeds, where they find food, shelter, and breeding sites. Population density varies with prey availability, water access, and human disturbance. Protected areas and intact corridors remain essential for long-term persistence acros
Physical characteristics and behaviour
Adult sea bunnies typically measure about 0.025 m in length and weigh roughly 0.001 kg (0 lb). They can sprint at up to 0.2 km/h (0 mph) when hunting or escaping predators. Sea Bunnys are known for the tiny nudibranch that went viral for looking like a miniature rabbit — social structure, daily activity, and seasonal movements all reflect pressures in their native environment.
