SEA HARE
Aplysia spp.
DESCRIPTION
Sea Hare (Aplysia spp.) is a type of marine gastropod mollusk known for its unique appearance, which includes a soft, elongated body and a pair of large, ear-like structures called parapodia. These creatures are often found in shallow coastal waters and can exhibit a range of colors, from green to brown, depending on their environment and diet. Sea Hares are known for their fascinating behavior, including the ability to release a purple ink as a defense mechanism when threatened, which can confuse predators and allow them to escape.
FUN FACTS
- Sea Hares are named for their resemblance to the ears of a hare, with their large parapodia resembling rabbit ears
- They are also capable of changing color based on their diet, which can affect their camouflage in the environment
