The platypus is a semi-aquatic mammal found in eastern Australia. It eats small aquatic animals like shrimp, fish, worms, and insect larvae. Platypuses have predators like red foxes, feral cats, water rats, snakes, and birds of prey. They inhabit streams and rivers from Tasmania to Queensland. Adaptations like webbed feet, fur, and electroreception help the platypus swim, stay warm, and find food in its aquatic habitat. Males have venomous hind legs and the female carries eggs that hatch from skin glands rather than laying eggs.
