I need skin from thos buggers to upgrade my loot bag, but just how do i do it? Got no weapon that work underwater, and if i blow them up from land i just get damaged skins, any advice?

Go swimming and when it starts chewing on you attack it with your knife.

I jumped in and when they came near me i got on shore and sniped them.

i stept in a boat and shoots them.

What I did for this (cause I wasn't sure at first) was look around the water area with your camera; when fish are in-view it should mark them. Then I just stood on the shore line and shot into the water with M72 and it wasn't a problem. But yes normally u can use Bow or Guns to do this. But if a mission calls upon u to kill with a certain weapon, then u must use only that weapon for the quest, otherwise it will fail u.

Find a body of water with a ledge above it. They're easy to see when you're looking down on the water.
