Description & Biology

The Seacat is a flat sea hare that grows to about 10 cm long.[6] The maximum recorded length is 108 mm.[7] It is commonly spotty green or brown, but it can also be reddish.[6] The animal's back half is typically wider and rounded, it narrows towards the head.[6] Warty Seacats are soft-bodied gastropods, who have lost a protective shell over time.[4] All species of sea hares have ink glands for chemical defense, though Dolabrifera dolabrifera does not release ink.[8]

Distribution

This species is found in warm tropical and subtropical waters.[6]

Habitat

These animals are majorly preyed on in their habitat.[4] The Seacats live in shallow-flat pools that contain large boulders, near-shore.[4] Collections of the hares gather underneath rocks in the intertidal zone.[9] At night the warty Seacats hide themselves in between cracks found in the boulders.[4] During the day, when the tide rises, the Seacats emerge.[4] Due to the varying in color and pattern, it is hard to distinguish them from other species in the habitat.[10] The minimum recorded depth for this species is 0 m; the maximum recorded depth is 3 m.[11]
