A passively tamed creature that requires you to,”Feed” it a school of parakeet fish. (Tiny glowing schools of blue fish that look like drones, usually around the turtles themselves.)
You need to aggro the school of fish by walking into them which gives you a,”You are being targeted by a Microbe Swarm” pop up, then slowly lead the school to the turtle and swim alongside it which automatically starts the taming progress at 0% which then slowly climbs to 100%. During the taming process Sabertooth salmons and coelacanth will randomly spawn around the turtle and try to kill the school of fish to stop the tame.
However this can be easily cheesed by killing all the salmons and bigger coelacanths until a small coelacanth spawns which cannot keep up with the turtle and the school of fish, so let him try to catch up while the taming bar fills up.
Scuba gear is also not necessary, as the turtle constantly produces oxygen around it which refills your oxygen meter.
Probably the best platform dino to live on, the megachelon can fit a 5 by 7 of foundations on its shell, and many structures, like chemistry benches, grinders, and even industrial forges can be built on it while staying there when underwater. You don't even need scuba gear when going underwater, staying above one provides oxygen. Not only this, but they actually have surprisingly good melee damage, as well as being one of, if not the best fiber harvester in the game. Different resources will constantly build up in its inventory, including rare mushrooms and flowers. They also automatically irrigate any crops placed of them. Get an imprinted one for extra speed, damage, and resistance, then give it an good armor saddle from the frog escort mission in the bog, and you have an extremely tanky resource gathering portable base, war machine, greenhouse, and water exploration mount!
Lead it into a line of stone behemoth gates and close a gate behind it and it will be trapped or you make a square box of Dino gates and nothing can mess its taming up while it’s being tamed so up this!!!!!!!
Go into the ocean in fjordor around the swamp island In the west of the map. You should see some turtles so to tame them find a school of fish and let them follow you to the large turtle. Swim beside it and try and get the fish to target the turtle. This will start the taming process keep doing this till tamed. For the saddle kill the turtles to get shell fragments and combine 22 of them with standard materials in a smithy. You can build on their saddle but don't cryopod if you have built. Make sure others see this
Ps: they are originally from genesis 1 in the ocean biome.
They have patched the render range range so ignore any tips that say to leave render as it will no longer. Guess I’m stuck with the turtles I have, I’ve spent three hours trying to take one of these things and had it walk out of the water which reset it taming! It was at 80% that time. Never got it above 20 after that. What he for the saber tooth salmon that spawn to kill the swarm if they bite the turtle it resets to zero and you start over. Extremely frustrating way to tame a creature. I would like to beat whoever came up with this idea.
If breeding on Lost Isles head to 42.5 lat 17.8 lon. you can breed in the bottom of that mini trench thing. Area is too hot to hatch in but you can just build a mini hut with an incubator and gen at the bottom. Set incubator to -5 that's my sweet spot.afterwards cryo it up ride to surface and imprint.
