There is an internal black eye within the posteromesial base of each tentacle. Distinctness of eyes varies with intensity of body pigment and amount of flesh they are viewed through; the eyes in the wet one in this image are less distinct as the overlying tissue is more swollen with absorbed water. The head in front of the tentacles forms a broad, slightly bilobed muzzle which can be variably configured, but not cylindrically to form a snout like that of many marine gastropods.
