🔵🦈 I can’t help myself… I just have to post this wee clip again!
I love how you can see the incredible blue colouration of the dorsal side of this shark as she catches the sunlight when cruising on by!

Sharks will sometimes use their mouths to check things they're curious about. Or touch with their nose

Some people mistake this for aggression but it's not. It's just how they explore their surroundings
