Dolphins and beluga whales blow bubble rings and swimming through them, and tend to do this more in captivity, indicating the behavior might be a boredom-buster for them. A parallel theory is that it's a form of play and Balcombe suspects that, whatever the answer, they find the activity stimulating. Image by Hiroya Minakuchi/Minden Pictures via Wired
National Geographic Photo Contest 2011 - Beluga whales in the arctic having fun. (Dafna Ben Nun)
The Beluga Whale also called The White Whale can mostly be found in Artic waters and become their brilliant white color around 5 yrs. of age. They are considered a smallish whale between 13-20' long and live 35-50 yrs. in the wild. They should never be kept in captivity.... it is inhumane and unjust. All whales should have the roam of the ocean!
