They’re highly directional and help with smooth swimming. And they’re basically thousands of little teeth rather than actual scales. They have the same structure as teeth too, a pulp core surrounded by dentin, with an enamel exterior.
They’re not razor sharp due to being so tiny, but are as coarse as sandpaper.
Sharks are absolutely not smooth. There’s a reason why they use shark skin to grate wasabi in Japan.
They have very directional scales. One direction they’re very smooth, the other direction they’re like razors.
It’s weird you say that, 'cause every shark I’ve ever pet has been super smooth. In every direction.
