Day 179

Day 179


While Etna makes rings of smoke, dolphins make rings with air.

These graceful cetaceans shape perfectly circular rings, called toroidal vortices, from their blow holes and purposefully play with them. Sometimes they let them rise to the surface and dissipate, but they love to push them down where the water pressure keeps them compact and in tact. Sometimes they will bite the bubble, to make two and they might give the second one a push sending it through the first.



They can spin the rings without touching them, by creating turbulence in the water around them or create a looser, wiggly bubble that they swallow up right before it is about to burst.

Dolphins radiate playfulness. They even look and sound like they are laughing. When I see a dolphin I can’t help but smile.
