This design celebrates the Ganges River Dolphin – one of the most intelligent and endangered mammals. Smart as apes, the evolution of their brains is surprisingly similar to humans. Like us, they live in groups and even play together.Unfortunately, pollution, fishing, and hunting have put the species in danger. This design makes up for a great conversation starter with our count the dolphins puzzle. A perfect opportunity to tell people about this smart creature. And for those who engender their cause, the answer comes with the Tee.
