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

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.

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

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.

An underwater tank who is immune to jellyfish stings AND acts as a giant scuba tank for its riders. Oh, and it passively produces the equivalent to mutton for herbivores. Facing something you'd rather avoid in the water? Just take your turtle onto the land; that's right, despite not having an O2 stat, this mount can also travel on land. For how easy it is to tame, this thing offers incredible value to any tribe that has one.

When breeding Archelon, make sure the babies are fully submerged in water or they will die. In addition, they can be fed with cheaply produced kibble (such as Basic Kibble) if you are running low on biotoxin
