In a few years, which country's explorer discovered the platypus and sent his appearance back to his own country, which was considered a joke by people in his own country?

platypus is one of the most primitive mammals. Its tail is flat and wide, and its front and rear limbs are webbed and clawed, so it is suitable for swimming and digging. The platypus burrows near the water and feeds on worms, aquatic insects and snails. When breeding, the female platypus lays two eggs at a time, and the cubs lick the milk from the wet hair on the mother's abdomen. It is only distributed between Cape York in eastern Australia and South Australia, and also inhabits Tasmania. In addition, platypus is one of the few mammals that defend themselves with venom, and it is a precious monotreme.
