Smart creatures

Dolphins teach their children to use sponges
This is amazing. But, then again, why should it be? Humans are pretty arrogant to think that they’re so far advanced that there isn’t even one reasonably smart creature out there.
“Dolphins in Australia have been observed using tools, and they seem to pass on their specialist knowledge to others. This is the first time cultural transmission has been confirmed in a marine mammal.
“Lacking hands, dolphins are limited in what they can do with a tool, but some bottlenose dolphins in Shark Bay, Western Australia, have devised a way to break marine sponges off the seafloor and wear them over their snouts when foraging.”
