beautiful-I had to share this, Dolphins Blow Water Rings To Hunt Fish It’s common knowledge that dolphins are among the smartest and most playful animals in existence. Yet researchers are still often surprised by the bounds of cetacean creativity—when studying younger individuals, it was observed that they engage themselves by blowing the aquatic equivalent of smoke rings. The cuddly sea mammals can form all sorts of rings and bubbles—they’ve even been seen playfully whipping up small vortexes like a child creating whirlpools in the bathtub. Furthermore, dolphins often use their fins to manipulate the rings—sending them in different directions, combining them into larger rings, and even threading the needle. This might seem like pure whimsy, but studies have shown that dolphins use these rings to hunt prey as well. They do so by swimming underneath a school of fish that they wish to eat and then blowing ring after ring until the fish either get trapped in the bubble vortex or get blown away from their school and are left alone for easy pickings.
