Title : "Exchange" - Nembrotha chamberlaini nudibranchs mating

Description : Nembrotha chamberlaini nudibranchs mating at Twin Rocks and Red Rock in Anilao, Batangas, in the Philippines. Nudibranchs are hermaphrodites. They contain both male and female reproductive systems. During copulation, they line up their genitals which are on the right side of their body. The penis, which is off to the side, is covered in tiny, sharp barbs which lock it into the vagina, which is at the center of the stalk. Each nudibranch receives sperm from the other. When the nudibranchs have finished mating, it takes quite an effort to pull the genitals apart. I shot this footage while diving with Crystal Blue Resort (http://www.divecbr.com) on their annual Critterfest workshop. Thanks to dive guide and critter spotter, Jomel.
