Shark's only smooth from front to back. Otherwise shark's sandpaper.
Nope. Sharks are smooth as hell in all directions.

It’s telling me that shark skin is “smooth from all directions and at all times”
Are you reading the same thing I'm reading? Literally every search result describes shark skin as dermal denticles, or sharp tooth-like scales aligned from front to back, "relatively smooth" in one direction, and sandpaper-like in the other.
Apparently other animals regularly get injured brushing up against them.
Well, I'm touching a shark right now. Rubbing it every which way. No direction is off limits. It's smoother than the finest silks
But other question, is shark wet?
Presumably their skin doesn't absorb or hold water much, if at all. So shark is probably dry
No, sharks are smooth all over.
