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!

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.

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

BREEDING: babys need to be in the water. In my testing the babies start to take damage if they're on the land just before 25% raised (part way through the juvenile stage). You can hatch them on land you just need to transfer them into the water before that point. Thank you to everyone else that put up breeding tips about this!

To tame the Archelon you will need bio-toxin or kibble, once tamed the Archelon can eat mejoberries so you don’t have to keep killing jellyfish

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

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.

They will eat berries after taming

If staying near the surface, which tbh most already do, you can hop on their back and passively feed biotoxin, especially helpful for higher levels

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
