Learn all about the "sixth sense" of the Duck Billed Platypus and the assistance that this power provides in protecting their eggs and in hunting. Viewers learn that the platypus has a sense called electroreception, which allows them to sense electrical charges to figure out what is in the environment around them. The Kratts also teach that the platypus is the only egg laying mammal, can see even in the darkest water, and love to eat crayfish!
