Sneakier sand shark

Stakhanov

So far , I haven't had any serious encounter with sand sharks due to how conspicuous they are : either they'll be floating a good distance from the ground , or they'll be throwing sand all over the place. I think they should behave differently to increase their chances of catching the player unaware : first , give them a better awareness of their surroundings - they should hide in the sand when spotting seamoths or cyclops (after all , they're not quite at the top of the food chain) and that should be the only time they throw sand. When hidden , they could only be spotted from their fin sticking out of the sand , until they make their move ; they should have an extensive sight range in that state , leaving the sand once they lose track of the player for too long. If they spot the player while swimming freely , they should stay close to the ground to blend in better.

I think that particular fish has the potential for some nice scares , just like the crab snake - but less predictably.
