It occurs in the intertidal zone and down to at least 10 m[2] on coastal areas of the Indo-West Pacific oceans, the Caribbean Sea and the Mediterranean Sea. DescriptionBursatella leachii is green to greenish brown. It has a broad and short head. Its mantle is covered with papillae (finger-like outgrowths), which give it a thorny aspect. The mantle has a network-like pattern with blue eyespots (ocelli) in black spots and green areas. It moves slowly on a broad foot. There is short, sharp tail. The short parapodia (fleshy, winglike outgrowths) are fused on their rear end. The maximum recorded length is 120 mm.[3] EcologyThe species is usually found in estuaries and tidal pools, and more rarely on sandy bottoms. The minimum recorded depth for this species is 0 m; maximum recorded depth is 7 m.[3] This sea hare may be found in dense concentrations or singly. It is herbivorous. The species lays egg ribbons in long green stringy tangles.[4] SubspeciesThree subspecies have been described:
