@tranquil.getaway3: Hypselodoris Nudibranch (Mating) Slow-moving nudibranchs are called sea slugs for a reason. Therefore, unsurprisingly, finding a mate can be tricky. In order to maximize their chances of reproducing, nudibranchs have a curious adaption.. Depending on if the other nudi is male or female, nudibranchs will change their sex so that they are always able to mate #TranquilGetaway #ExploreUnderwater #scubadiving
