Best way to deal with these things. Shotgun and raft combo. You sail the raft close to them, stand on edge of raft, and shoot them point blank. These jellyfish are worse than the Box jellyfish and or man o’ war jellyfish we have ILR, and need to be exterminated.

Side note. The raft and shotgun combo works for exterminating other hazardous sea life as well. Like so that new players will know how to deal with these things efficiently.

Another side note. Rafts are perhaps the best thing to have if you plan on taming any sea creatures. Put a generator and an auto turret on a raft to make a mobile safe zone for your aquatic tames. It really helps.

Another side note. Auto turrets are mid to late game, generators are mid game. Be wise with your engrams, and be sure to follow the below strategy.

From level 1-75 unlock all the weapons and saddles, then produce two of each saddle. After which, you’ll want to use mind wipe to reset your engrams and unlock all the armor. Produce two sets of each armor. Mind wipe a second time, then use your engrams to unlock whatever else it is you may need. That mind wipe is perhaps the most useful recipe in the game. Best way to get the recipes is to go to a cave and farm the creatures in there for recipes and ammo. Always be sure to check the inventory of everything you kill, you might find some useful gear.
