1. What Exactly is a Sea Bunny?
The sea bunny, scientifically known as Jorunna parva, is a type of nudibranch, a soft-bodied marine gastropod mollusk also known as a sea slug. These tiny creatures are native to the Indo-Pacific Ocean, particularly in tropical waters. Their name comes from their striking resemblance to a fluffy bunny, thanks to the sensory organs on their head that look like rabbit ears.
1.1. Appearance
Sea bunnies are small, typically less than an inch (2.5 cm) in length, about the size of a paperclip. They come in various colors, including:
- Orange
- Yellow
- White
- Green
They are covered in tiny speckles, usually brown or black, which add to their fuzzy appearance. This fuzziness comes from small protuberances called caryophyllidia, which they use to sense their surroundings. They also have longer, thinner fibers called spicules. The “bunny ears” are actually rhinophores, chemoreceptors that help them detect chemicals in the water.
