grooved brain coral

Close-up of the grooved brain coral, Diploria labyrinthiformis, is a common reef–building coral in the Caribbean. When under stress, these animals may harbor a species of mutualistic microbe, that was recently discovered to be introduced from the Indo-Pacific. The symboint increases the stress tolerance of native corals, but may significantly reduce the animal’s rate of calcification, thus diminishing their role as reef builders.
