🦄 Narwhal fun facts!🦄 Did you know that the long spiral tusk of a narwhal is actually a tooth? 🦷 Narwhals are born with only two teeth, and in males, one of them grows into that iconic tusk. The other one stays hidden. Their mouths are all gum — talk about a way to keep dentist bills down! 😄💸 Bonus: It’s almost always the left tooth that turns into a tusk! Both teeth erupting is very rare, and it’s even rarer for females to have tusks! 🌊 #wildlife #marinelife | WWF-Australia
