A. loveni with poorly developed, widely spaced tubercles. Apices of some tubercles (1) resemble the rounded points on A. proxima, but most tubercles have a broad base (2) as on typical A. loveni. Dull orange organ behind the rhinophores might be the buccal mass; this is not a feature of A. proxima. Norway January 2011 and February 2017. © N. Aukun.
