Platypus swims to Croatia

The platypus is one of the world's weirdest mammals. It's genetic coding is partway between reptile and mammal and it lays eggs. Even having seen the real thing, it is hard to believe it is an actual animal. When swimming it closes eyes, ears and nostrils, and effectly hunts via electrolocation. It does this by swishing its head from side to side as it swims, or digging in the river bed with its snout and can detect movements of living things and pinpoint them. Male platypus have venomous spurs which they use in dominance battles with other males. Females have spurs, but no venom.
