I like the idea of being able to make ‘trophy’ style item out of Sharks. Similar to the Boss trophies. So, for example, you kill a great White shark, Instead of harvesting the shark for it’s rawhide/meat, you would have the option to craft a trophy for display purposes. The trade off would be that because you are making a trophy out of the Shark, you don’t get the rawhide/meat. It could also be set up so that you could only create these trophies after you reach a certain crafting level.
The same could be applied to boars and snakes as well. Just an idea.
