dwarf sea hare

Aplysia parvula was long seen as a circumtropical sea hare species, but Golestani et al. (2019) restricted the name A. parvula to the population from tropical waters in the northwest Atlantic, while resurrecting A. elongata, A. japonica, A. atromarginata, and A. nigrocincta for populations from the Indo-Pacific and describing the new species A. ghanimii and A. hooveri for populations from the eastern Pacific.{{cite journal | author1 = Haleh Golestani| author2 = Fabio Crocetta | author3 = Vinicius Padula | author4 = Yolanda Camacho-García | author5 = Joachim Langeneck | author6 = Dimitrius Poursanidis | author7 = Marta Pola | author8 = M.

The dwarf sea hare is round-bodied and smooth-skinned with a slender head bearing extensions which resemble rabbit ears. There are wing-like flaps (parapodia) extending from the body, which is brown to maroon or olive green in colour and may be covered with clusters of white spots.Gosliner T. M. (1987).

The maximum recorded length for this animal is 60 mm.Welch J. J. (2010). "The "Island Rule" and Deep-Sea Gastropods: Re-Examining the Evidence". PLoS ONE 5(1): e8776. {{doi|10.1371/journal.pone.0008776}}.

The minimum recorded depth for this species is 0.5 m; maximum recorded depth is 30 m. It usually occurs in less than 5 m of water, but is occasionally found in water as deep as 24 m.Zsilavecz G. (2007). Nudibranchs of the Cape Peninsula and False Bay. {{ISBN|0-620-38054-3}}

The species is a herbivore, and feeds on different types of algae. Its egg mass is a tangled mass of sticky orange, green or brown strings found under rocks or among algae.
