Male Harlequin Shrimp w/sea star

The male harlequin was feeding on this sea star and by the looks of it has been doing so for a very long time. The harlequins will keep a sea start alive by feeding it while feeding off of it. The sea start grows its arms back and the Harlequins eat them. Devious but ingenious.
