The shark is huge and is grey in color. It will open its mouth revealing its teeth and gums. Its gums look like raw shark meat. The shark appears to be a great white and will chomp the players raft once this happens it will shake violently and damage the raft.
The shark can kill you and destroy your raft. If you spear it in time that foundation is damaged and can only be repaired with the repair hammer. If you manage to kill the shark you will get a max of 4 shark meat and another one will respawn. The easiest way to kill it is if you stand in an item net and wait for the shark to come to you. When it gets close enough you can hold down your spear and kill it.
