"Material. Station E76 - 1 specimen (43 mm in length/ 27 mm breadth); E100 - 1 specimen (36 mm length/15 mm breadth); E107 - 1 specimen (85 mm length/44 mm breadth); E129 - 1 specimen (56 mm length/36 mm breadth); E131 - 4 specimens (80 mm length/37 mm breadth, 79 mm length/38 mm breadth, 49 mm length/28 mm breadth, 69 mm length/32 mm breadth respectively); E148 - 2 specimens (102 mm length/59 mm breadth, 48 mm length/19 mm breadth); E152 - 1 specimen (40 mm length/15 mm breadth); E153 - 1 specimen (81 mm length/32 mm breadth); E155 -1 specimen (80 mm length/51 mm breadth); E275 -1 specimen (66 mm length/39 mm breadth); E370 - 1 specimen (44 mm length/20 mm breadth); E377 - 1 specimen (52 mm length/32 mm breadth); E381 - 1 specimen (35 mm length/24 mm breadth); E408 -1 specimen (51 mm length/33 mm breadth); E554 - 1 specimen (69 mm length/26 mm breadth).
External anatomy. The size of the preserved specimens varies from 36 to 102 mm in length and from 15 to 59 mm in breadth. The notum is wide and covers the foot completely. Dorsally, the animals are covered with tubercles of different sizes and number. Sometimes there are spicules in the notum that may form caryophyllidean-shaped tubercles on the branchial and rhinophoral sheaths.
The gills, 6 to 10 in number (normally 7 or 8), are bi- or tripinnate. The number of rhinophore lamellae changes with the size. Thus, 40, 28 and 18 lamellae were counted in specimens from the station E131 (80, 49 and 69 mm length, respectively), 19 lamellae in a 48 mm long specimen from station E148, and 23 lamellae in a 69 mm long animal from E554.
The body is pale yellow or whitish.
Internal anatomy. The radular formula in two specimens. 80 and 66 mm long respectively, is 33 x 43.0.43 and 43 x 60.0.60. All the teeth are smooth and hook-shaped. The smallest teeth are the innermost and outermost ones.
From the gonad emerges a thin hermaphroditic duct, with moderately enlarged, zigzag-shaped ampulla. The deferent duct lying within a muscular sheath, is long, coiled and somewhat enlarged at its distal end. The fertilization duct is thin and bifurcates into the oviduct and a vaginal ducts. The former is thin and penetrates the female glandular complex. Proximally the vaginal duct is thin, up to the point where the elongated seminal receptacle and the round, thin walled gametolytic gland insert. Distally the vaginal duct is coiled and slightly enlarged. The female glandular complex is large and covers part of the gonoducts.
Remarks on the diet of A. kerguelenensis. Observations of stomach contents of several specimens of A. kerguelenensis revealed the presence of poriferan spicules belonging to the Demospongiae Myxillidae Ectyodoryx cf. ramilobosa and one dractine of the Hexactinellidae Rossella sp." (Garcia et al, 1993)
Doris kerguelenensis is a species of sea slug, a dorid nudibranch, a marine gastropod mollusc in the family Dorididae.[2]
The type locality for this species is the Kerguelen Islands. It has been widely reported all round Antarctica but molecular investigations suggest that it consists of a species complex and many of the synonymised names may be valid.[3][4]
