"Sea Bunnies" are a type of sea slug called Jorunna parva. Most of them are less than an inch (2.5 centimeters) long and can be found throughout the Indo-Pacific Ocean from South Africa to the central Pacific. Though the most images of these animals show white animals with black spots, these sea slugs are usually yellow or orange.
