Yes, Merlin the dolphin has an iPad, and he and his trainer are using it to better understand each other's communication patterns. If successful, the Apple gadget may help break the dolphin-human language barrier. Ever since the debut of the iPad, there have a plethora of cats, dogs, birds, and mice playing with the Apple gadget.
