What facts about animals do you know that will surprise me?

Duck-Billed Platypus

The Duck Billed platypus is the only egg laying mammal. They are small, shy animals having a flattened head and body to help them glide through the water. Their fur, dark brown on top and tan on their bellies, is thick and repels water to keep them warm and dry even after hours of swimming.

The duck-billed platypus's head and body grow to about 15 inches (38 centimeters) and its tail grows to about 5 inches long (13 centimeters). Their most remarkable feature is their amazing snout. It looks like a duck's bill, but is actually quite soft and covered with thousands of receptors that help the platypus detect prey.

Males are also venomous. They have sharp stingers on the heels of their rear feet and can use them to deliver a strong toxic blow to any foe.
