These guys are great and super fast and also very strong. Warning when your gonna go tame these guys bring a sarco or an icthy , they also spawn In 2,s or 3,s so be careful because these guys do a crap ton of damage .
They can't fit through the resource caves' entrances. Just lure it into one and pull out your crossbow/harpoon gun for the knock out. Just be aware of any nearby megalodons, as they can fit into the cave easily and ruin your swimming session.
