The Platypus is a monotremes, meaning
they lay eggs instead of giving birth to live young. The only
relatives to the Platypus are all extinct, making it the sole
member of its family. Male Platypus' have a poisenous spur
on the back of their rear feet. The poison is so strong that
it has been known to cause damage to humans. When the Platypus
was first discovered many scientists thought that it may be
a joke just due to their odd appearance.
