Ribbons of red nudibranch eggs curl near Malaysia's Mabul Island. Nudibranchs, also called sea slugs, lay their eggs on the seafloor, attached to coral or rocks. Although a nudibranch is a simultaneous hermaphrodite (possessing both male and female reproductive organs), it reproduces by finding a partner. Millions of eggs can be found in one egg spiral.
