Platypus

The platypus is a semi-aquatic egg laying mammal. It lives in the eastern part of Australia, in wetlands, freshwater rivers and ponds. They eat small fish, aquatic invertebrates and sometimes amphibians, using their bill. In approximately 100,000 - 5,000,000 years from now, they will switch to land hunting because of the pollution in the rivers and deforestation in the wetlands, their bills will evolve into a beak for a wider variety of foods. The beak will still allow them to eat invertebrates, but it will also allow them to eat insects, small animals and carrion. The platypus bill of today is a soft leathery compound with thousands of electroreceptors and mechanoreceptors to help the platypus fish underwater without seeing. The platypus might get a secondary layer of protection over their eyes to be able to look underwater and the beak will turn tough, to circumvent pollution.
