Just use a squid those things are tanky because they can have a lot of health

Basilo is the best to gather bio toxin because it can't get stun by the eels and the jellyfish

For Ark Mobile easy tranq arrows no need for infrastructure.

Tame a ptera and go searching the coast. Either use dilophosaurus bow or terror bird sword with better duds boots to kill and harvest the biotoxin. Then when you have a satisfactory amount of biotoxin go to one of the glacier islands and farm the penguins for polymer. Then comine 5 biotoxin, 2 polymer and an arrow for toxicant arrows. They deal much more torpor and the torpor of the creature rises for 10 second meaning if you tame runs away they most likely will knock out while running! I got 300 arrows in 2-3 hours.

Just go around with your raft on orbit camera so you can see underwater and if you see some jellyfish close the surface hip in the water and kite them to the raft hop back on take out longneck shoot them harvest with pick got over 1000 toxin doing this

This is the best for taming and the best way to farm it is get in the the water to bring the jellyfish to the beach and get out of the water and then shoot them with a bow or a gun (anything that can kill from a distance.)

For crystal isles, breathe fire into water spheres in the mountains... sooooo much toxin

How do you get this on lost island?

Use these for taming something you aren’t experienced in taming, also depends on the torpor drop. I personally use only this to keep stuff I’m taming down, easy to hunt at south zone 3 on Mobile, as cnidaria spawn near the shores, easily killed with either a pike or spear. Just one thing, never use a low level mosa, any amphibious mount that aren’t strong or tanky, a dunkle, any weak aquatic mount for that matter to kill jellyfish, if you already think that the eelectrophorus are tough for you. A basilosaurus, you on the shore with a spear, a tusoteuthis, a high lvl tanky mosa that can one bite everything or a tribemate would do.

Use a blood stalker to drag it onto land that insta kills it then harvest it with a chainsaw

eating the stuff will regenerate 20 Health and 20 food

I know I am supposed to submit a tip but how does the character even touch this when it’s electrocuted

Oddly enough use master carft rank bow and pike for me seam to be the quickest and and safest way to gather this cus some how the arrow that fire form above water seams to do the same with crossbow underwater -reloding speed.

You can go on shore with a bloodstalker and grapple them out, as soon as they come out of the water you harvest with a chainsaw, just make sure not to get in the water with them, they can shock you when you’re on the surface

Always have as much as possible. Use them to tame electric eels. Eating bio toxin causes damage to awake creatures, doesn't to unconscious ones

Basilosaur is easy to tame with dolphin and they are good and probable the vest for getting this bio toxin

These can be used to get even early game.

Omg it’s so good for keeping stuff down much more effective than narcotics you can go down to the sea and kill jellyfish with a basilosaurus since they are immune to all the jellyfish attacks and saves you a lot more time than waiting for meat to spoil and pick the narcoberries and craft them. 4 times more effective and it can be used to keep gigas down at a less amount.

The Tusotuethis is definitely a recommended tame for these due to not being dismounted when you get stung, plus your long range allows you to damage the cniderias from a distance, so you don’t get stung irregardless and you’re also able to hold your own in the ocean quite easily, in case all the cnids are only at the bottom

Random frog is the same as a kraken to gavering deadly poison sacks from huge jellyfish

When using the spino for gathering biotoxtin you need to use the range it has with its snout and stay on land for easier gathering

The best way to get an abundant amount of this stuff is to kill cnidarias with a chainsaw
