There are few records of this distinctive nudibranch probably because it burrows into soft sediments. It can reach 40 mm in length. The mantle is a reddish colour, with up to 50 prominent white longitudinal irregularly wavy ridges. In places the ridges can be replaced by a row of pustules. The mantle rim contains numerous large defensive glands (brown in preserved animals). According to Thompson (1988)Armina loveni is always found in mud, in sheltered localities, among beds of the pennatulacean cnidarian Virgularia mirabilis, on which it feeds. See photo on Bernard Picton's nudibranch site showing Armina feeding [http://www.pictonb.freeserve.co.uk/nudibranchs/armlov.html]. Subtidal species to 75 m depth.
