I finally tried attacking some of these with an expendable spino, and I figured out that you just need to attack the jellyfish before they attack you. If you level the damage to about 250%, you can kill the average jelly in three hits, and they harvest more biotoxin than other creatures.

(My giga harvests 12 per jelly, baryonyx is 16 per jelly, and the spino is 18 per jelly). I promise you guys that itโ€™s real. Itโ€™s only a problem if you let your tame get too close and then get stun locked by the electric attack of the cnidaria. Keep your distance and murder these suckers for the best narcs in the game! Good luck
