Сделайте что-бы с акулы выпадала кожа :) sorry for my Russian
I used Google Translate to see what you said, and it translated to: "Do something to fall out with shark skin"
I agree, shark skin would be very useful. It could be used to make water-resistant bags as well as clothing (boots or swimming fins would be good). I'd suggest adding a drying rack as well (to dry out the shark skin into a leather so it's easier to work with).
