Why? Probably because they hit low, also, they drop food so you can easily continue dharoking for long periods of time. They mostly drop raw, but just outside the cave is a fire (that is, if you've done olaf's quest). Most of their drops are really good, includeing many sharks, and charms aren't lacking either. You'd make a hefty sum, if you sell everything. If you hit upon a brine saber (i got my first one after around 50 kills), its free 15k+. EDIT: Oh yea, i forgot, they drop noted food A LOT, if your short on food, just collect the raw meat they drop. Hmm...I'll try this. P.S-Onagi teacher Rocks , haven't watched it in ages though.
