Chelidonura sandrana is a species of sea slug, or "headshield slug", a marine opisthobranch gastropod mollusk in the family Aglajidae. [2]

Distribution[edit]

This species lives from Tanzania to Australia.[3]

Ecology[edit]

Chelidonura sandrana is a simultaneously hermaphroditic species.[4] Contrary to classic theoretical predictions, Sprenger et al. (2011)[4] have shown for the first time that the mating rate is largely unresponsive to variations in mate availability in this simultaneous hermaphrodite.[4] With mating rates being close to the female fitness optimum, their findings challenge the prevailing notion of male-driven mating rates in simultaneous hermaphrodites, and call for complementary investigations of mating-rate effects on fitness through the male sexual function.[4]
