- I was at the aquarium/oceanarium in Chicago last weekend, and noticed that
- the two Beluga whales in a large tank were doing something rather strange.
-
- They were just breaking the surface from underwater, collecting a small bit
- of air, and blowing it under water into perfect rings (similar to smoke rings.)
- After the rings spun and grew and moved a bit, the whales would swim down and
- bite part of the ring, or try to swim through it, until it collapsed. Then
- they went back to the surface, and did it again.
-
- A staff member there told me that the whales had just started this within the
- last month, and the staff had no idea why they were doing it.
-
- Is this common behaviour of whales in captivity, or in the wild? Does it
- serve a function? Do other animals play in a manner similar to this?
-
- Thanks for any information,
- Dan
