This may or may not be applicable to Belugas, but there are some species of whale that blow rings as a means of prey capture. I saw a TV doco which showed whales off Alaska blowing bubble rings to herd up fish or other prey, and then dive down, coming up through the ring at the surface, mouth open. I guess in the pool it may be a result of confinement, boredom or some such, but there _is_ a purpose in the wild. I've also heard of dolphins playing with making bubbles and such from their blowholes. Mike
