You can raise them on berries not just toxin

Feed the babies Mejoberries easier to raise then using bio toxin

Breeding tip baby turtles eat berries and biotoxin

You can ride them underwater without a scuba!

I saw one on the Center as well. Should mark it as on The Center.

When raising baby Archelons they have to be fed Bio-Toxin or they'll starve, use a Basilosaurus to farm some before hatching.

Archelon is on the center, ive seen it near the redwoods forest beach

They are insane they literally create algae on themselves which can be used to tame herbivores and omnivores and algae is 4x more efficient than berries at taming

I have found that stocking up on biotoxin in advance is recommended for raising. Even mejoberry troughs are melted when raising multiple turtles. Biotoxin, in my experience, lasts quite a bit longer for sating their hunger.

Also: finding the “Slow Metabolism” trait and putting it on the babies will help save your troughs as well!
