Your one and only pest!
Ugh, what research would need a killed whale!?! It isn't the same as killing a deer in the least. You kill a deer that in a normal ecosystem probably would have been eaten by something anyway but, what eats whales! Also a single whale is worth more to the entire whale population then a deer is to the entire deer population. Rattler, would you care if people were killing off wolves legally by simple calling it "research"!?!
