Listen I got good strategy on how to kill these I killed one as a lvl1 you just get in water lure them to shore and then then they cannot reach you you but you can reach them so then just hit them over and over plz upvote so people see ps do not eat the bio toxin they drop
Using a quetzal, kill the ones on the surface for easy bio toxin, then use it to make shocking darts, which are better than tranq darts, or use the bio toxin as a better narcotic for being Dino's torpor up
They drop a pretty neat resource called 'Bio Toxin' when killed. It can be use as a steonger alternative to the Narcotic. It can also be used for a new 'Shocking Tranq Dart' which can shock the target and add a substantial amount of torpor. Perfect for knocking out Quetzal's.
