Narwhals, Tusked Whales of the Arctic !!!
The narwhal is not an aquatic unicorn. It’s not magical, or mythical. It’s just a whale with two teeth, one of which happens to be really long on males. But it’s not just its snaggle tooth — which can be up to nine feet long — that makes this Arctic sea creature unbelievable. The narwhal sees with sound — and it’s exceptionally good at it too, according to a study published Wednesday in the journal PLO'S One.
