Can very large animals sense a single fingertip touch on their skin or, say, the brushing of plant leaves as they pass by? I’m thinking of elephants, manatees, whales, large alligators. Especially whales, alligators and crocodiles which seem to have an almost dead. callous-like outer layer. Does skin hair provide a similar sensation as in humans?
I found this article among others that says that elephants have an excellent sense of touch. Everything I find about elephants says they have a good sense of touch and like to touch one another.
