Wanna get biotoxin without risking your Dinos? Find a school of these and get close enough to hit with a crossbow and aggro them - they’ll slowly swim closer. Draw them to a shore where you can stand and see them on the surface then shoot them with a gun. Once dead, check and make sure you didn’t miss any then harvest them with your axe. Gives about 15-18 biotoxin per jelly. Biotoxin spoils in an hour on you, 4hrs in a dino and 8 in preserving bin. Good luck!
If a cnidaria killed my spino, boy i would be mad. i lost my sarco to cnidarias, a scare with my icthy with cnidarias, and almost got my megalceros killed by some. ( he is dead now D:) I kill any of these that i can. The dossier says that they are passive, but aggresive when approched, NO! as soon as i step in the water these attack, and they litterally don't move at all, they just sit there and chill until you or a tame steps in the water. one like=one prayer for my deceased sarco, Gatorade (you can find his story in sarco) and one member of the cnidaria hate club.
I think that the devs need to reconsider some of the creatures in ark. With the jellies and electrophorus, it's too much. Especially on fjordur. There are hundreds of eels EVERYWHERE in the shallows! I don't mean reconsider as removal, but they need to be nerfed. No person I know tames mosas, plessies, or dunkies anymore because of those two creatures. They've made a lot of ocean creatures irrelevant. My first water creature is always a basilo. And that's all I need, because what's the point of anything else.
Ummm funny story so I just tamed a titan ok and I decide to swim back to my base with it and I see these things an I thought they wouldn't do anything but.... it got my titan and after 5 hours of trying to escape it killed my titan his name was Billy
