I believe that this was the third performer, an Australian sea lion. Here he (I recall that he was described as a male though I don't recall his name) has launched himself out of the water and has just made contact with the ball above.

A tasty fish treat will follow shortly.

Addendum: My personal opinion is that Facebook and all other members of the Meta group are disgusting, sociopathic organisations that steal other peoples' intellectual property (including the images in this gallery) despite being explicitly denied permission to do so.
