Oxygen tank strapped to his back, Michael del Rosario moves his fins delicately as he glides along an underwater nursery just off the Dominican Republic coast, proudly showing off the “coral babies” growing on metal structures that look like large spiders. The conservationist enthusiastically points a finger to trace around the largest corals, just starting to reveal their vibrant colors.
Del Rosario helped plant these tiny animals in the nursery after they were conceived in an assisted reproduction laboratory run by the marine conservation organization Fundemar. In a process something like in vitro fertilization, coral egg and sperm are joined to form a new individual.
