When a coral extends these filaments, usually it's an aggressive act. Using these mesenterial sweepers, it will sting its prey (basically a neighboring coral) and quickly begin consuming all it can reach during that session, and then those filaments are retracted back into the coral's polyps as if it never happened, leaving a dead skeleton mass where they touched. In this case, the filaments did nothing but it was neat to see. This coral is an Acanthastrea echinata.
