Draw your own conclusions

Following up on this item from earlier this month, I came across another BBC article detailing some interesting behavior by dolphins.

Wild dolphins in Australia are naturally learning to "walk" on water.

Six dolphins have now been seen mastering the technique - furiously paddling their tail fluke, forcing their body out and across the water.

The dolphins seem to walk on water for fun, as it has no other obvious benefit, say scientists working for the Whale and Dolphin Conservation Society.

That makes the behaviour a rare example of animals "culturally transmitting" a playful rather than foraging behaviour.

Look, I'm not saying that dolphins and penguins are trying to take over the world, and I'm not saying they're not. I'm just saying to keep an eye out. Especially for the penguins. "Flightless" birds are not to be trusted.
