Greetings coral-list,

You may be interested in watching an amazing video of French and Grey angelfishes attacking and eating sponges on a coral reef in the Florida Keys.  The video is here:
(Lower resolution than the HD it was recorded in, but still OK).
Be sure to turn up you speakers and watch the bait-ball come in at the end!

This video compliments our recent publication in PLOS ONE that shows that sponge communities on Caribbean coral reefs are primarily influenced by top-down effects - specifically predation by angelfishes.  You can access the paper for free here:
In brief, angelfishes focus their feeding on sponge species that are not chemically defended.  These sponge species grow or reproduce faster than the defended species (an example of a resource trade-off), so they persist on the reef despite being the target of predation.  There's a synthesis paper in BioScience at this link:
