Platypus (Ornithorhynchus anatinus)
Cute isn’t he? I bet you didn’t know this little sweetheart is also one of the few living mammals to produce venom. Males have a pair of razor sharp spurs on their back legs that secrete a venom when plunged into the flesh of an opponent. While the after effects of a platypus sting are described as excruciatingly painful, this venom is not actually lethal to humans. And if this fluffy little oddball didn’t already seem strange enough, you should also know that the Platypus the only mammal to lay eggs like a reptile rather than birth live young.
