>>213101498 (OP)I swam next to a basking shark while working offshore in Norway a bunch of years ago.
Coolest and most terrifying experience of my life.
Second largest shark species alive. It was like a huge semi truck swam next to me in the dark waters. It was feeding in the warm updrafts from the pressure lines from the drills on the bottom forcing plankton and stuff upwards.
Since then it's my favorite animal.
