Abstract
A young female Californian sea lion, born on 5th June 2011 at Berlin Zoological Garden, has been observed producing air bubble rings and playing with them by destroying. This behavior was documented on a digital video, a second digital video showing this behaviour has been found on the internet. The animal blows here the air forming a ring at the deepest point of the pool and repeated this behavior several times. It seems that the pinniped has refined this play comparing to the first video. Although there is some literature about whales playing with self-produced air bubble rings, there is only less notice for this object play in pinnipeds.
