Cnidaria cannot be tamed and are dangerous aquatic threats whose electric shocks can paralyze survivors, dismount riders, and incapacitate creatures, especially in groups. Fight them from a distance, lure them into shallow water or onto shore, or use a Basilosaurus, which resists their disabling effects. Harvested Bio Toxin is highly effective for maintaining torpor during taming and can also be used to craft Shocking Tranq Darts.
