A Brazilian biologist and a team of volunteer divers are manually removing invasive sun coral from an offshore oil platform near Ipanema beach, according to Mongabay. The coral was first seen in Brazil more than 40 years ago and has no natural predators in the region, threatening a marine protected area. The removal effort aims to protect the marine protected area from the spread of the species. Mongabay's report gave no further figures on the scale of the infestation or the length of the project.
