One of the best tames in the game. Tame one immediately. They are an incredible underwater tank, and are decently fast. They turn on the spot in water, and can crawl and live on land. They are immune to jellyfish and eels, and they can harvest biotoxin better than anything. After killing a jellyfish they gain and attack buff that makes it incredibly strong. Its saddle is an infinite oxygen tank, meaning you can never run out of air with it. Its saddle also holds four people so you only need one to do underwater stuff with your tribe. The algae it produces is a herbivore equivalent for mutton, meaning you have something better than crops to take herbivores with if you aren’t at kibble tier. Its algae can also be used in a recipe to make algae sushi, the only thing in the vanilla game that can restore lost taming effectiveness. It’s a passive tame with Biotoxin and can be tamed very early on and very easily. However it only eats biotoxin, including babies, and babies have to be grown underwater or else they will suffocate on land while babies. Tame as soon as you can, these things are one of the best in the game, by far the best aquatic tame.

Here's EVERYTHING to know about these seaturtles.

Finding them is simple, they spawn all around the oceans of the Island both in shallow and deep water, also they spawn with 3 jellyfish nearby most of the time, so be careful!

Taming is also very easy, bring a strong water creature, a crossbow (to kill the jellyfish) and bio toxin or exceptional kibble, once you find one you want to tame kill all dangerous creatures in the area, then feed the archelon until tamed.

Once tamed archelon will eat berrys, and can stay in the water or go on land.

Archelon are one of the most useful creatures in the ocean, they're saddle gives oxygen so you don't need scuba, and has 4 extra seats so your entire tribe can fit on one creature! They are also can't be stunned by jellyfish or eels, as well as the best bio toxin gathers in the game, and get a damage boost when they kill a jellyfish, but there's more, archelon will passively generate algae which can be used to tame herbivores at the same rate as mutton would on carnivores, or can be made into sushi which can recover lost taming effectiveness on any dino you're taming!

Overall, achelon is a great tame for ocean exploring, farming and taming. I hope this was helpful to anyone who was considering taming one of these guys.

These things are a GODSEND for water exploration! Their saddle is expensive but while riding it YOU DON’T NEED AN OXYGEN TANK. Other than the Grand Tortugar (Astraeos exclusive) this is the ONLY TAME THAT HAS THIS. They are also COMPLETELY IMMUNE TO JELLYFISH AND GAIN DAMAGE BUFFS WHEN THEY KILL ONE! Absolutely Goated tame!

Leveling the food stat will increase the amount of algae you get. And leaving it in the water lowers the timer

Babies has to grow in water until they reach adult, if you won't raise them in water in land they will die after few minites

Get this as fast as you can. The algae they make can be used like raw mutton for herbivores and can be crafted into a sushi that repairs taming effectiveness. Small tip, archelon produce algae faster in water, so it’s best to you have them next to shore, but still in water. Definitely a must.

I bred this turtle and then used it for underwater caving and it crushed tusos alpha megs and alpha mosas with the jelly fish amp

I would honestly say the turtle is just as if not better than the basi

Level it's food stat to increase the max amount of Algee it can grow before stopping.

Once tamed they don't require biotoxin to produce algae. They can eat berries straight from the trough.

Very useful to tame tusoteuthis, since achelon are immune to torpor and have a large amount of health to soak damage.
