The beps are known for making medicine and performing surgery on any animal that can pay or trade something for it. From carefully prepared gills from a rare type of screwcap, they make and store large amounts of painkiller for sale in bottles made from clapping worm secretions. They then carry these bottles to other towns for trade by adhering them to their backs. Clapping worm secretions are also used to make casts. Thorny crab pincers are used to hold wounds closed until they heal. Tools bought from square crabs are used to cut. Having no pathogens, the animals of Snax have no immunity cells as we understand them and so grafting is possible. Beps take advantage of this to perform organ transplants and also to grow clapping worm arms inside their screwcap homes in order to have a constant supply of medicine bottles. Some have also taken to farming gills, moving gill grafts from old screwcaps to young screwcaps, so they never have to hire sticker worms to gather them.
For currency, the beps use shell chips marked with the hands of famous (and credit-worthy) beps. While their shell-homes grow, they press their non-key hands into the soft parts repeatedly, leaving impressions. After the screwcap dies, its shell is broken apart into chips with these impressions still on them. Leaving a mark on another’s home is often a way of showing favor, giving that family prestige in the community. There are many other forms of currency on Snax, but bep shell chips are most used.
