When People were asked about most interesting animal,a lot of them said baby monkeys,fearsome lions.But the real answer is Platypus.
I am listing 4 golden reasons for it;
They Sweat Milk;
Platypus suckle their babies,they have many pores in their stomach,and kind of sweat out milk from these.Website popular science reports that their milk is full of potent antibiotic exclusive to platypus.
They Have Poisonous Feet;
Other creatures carry venom in their teeth or tongue,not platypus rather they have poison in their feet.They house miniature spurs, but these don't exist to immobilise it's prey, it uses it to scare other platypus(Reason for this is still not found)
They Have Strange Bodies;
Platypus are such weird animals that it would make sense for them to have weird biochemistry,"said scientist Dr Janet Newman who authored a study about platypus milk published in journal structural Biology Communications.Platypus have duck bill(a kind of hard snout),a beaver type tail,additional bones in their shoulders,lay eggs and have crazy eyes on the sides of their heads like a lamprey or hagfish.
Platypus Uses Electricity To See Underwater;
Popular scientist also reports that platypuses know where their preys are by sensing their electrical fields.Unlike most other mammals,they can close their eyes,nose and ears,which is exactly what they do when they swim underwater.Then they feel their way through the water using electroreception.
