If you just started the game, i reccomend you make a spear and kill a few, they are extremely easy to get, and i believe they give you prime meat. also takes two fully charged shots to kill one (headshots)
They are already wrong! It should say something more like:
"Found everywhere but the dark caves of the island, this creature will gladly ruin your day by jumping out and killing you as soon as you even think about going to the swamp. Nearly impossible to tame because it has to be tamed via passive which is very difficult to do. Worst of all you need to feed them fertilized eggs. Why can't it e a little easier?
