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

Posting a kewl thing about each of ark’s creatures

Slowly makes algea that can be used to tame herbivores, can also use the algea for sushi that ups the taming affectivenes. Makes more algea when in the water

if you stand in front of its back left fin? it stops moving only for about 15 seconds but hey anything helps

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.

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

They spawn at herbivore island for my first sighting was there.

with further testing you can also get a ai bug out by sitting on both left and right rear fins only for 15 seconds so not worth much

TAMING: Have your mount hit the archelon you want to tame (you might do this by accident will trying to save it), it'll aggro for a long time. Kite it onto the land and clear out any threats while you wait for it to catch up. Hop off your mount and whistle passive. The archelon will slowly chase down your tame allowing you to casually feed it bio-toxin or kibble from behind while picturing the steam roller scene from the first Austin Powers movie.

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.

They seem to share a spawn with Cnideria, so be aware of that. Can be useful because you can kill them for the bio toxin to feed the Archelon. I seem to see one beached everytime I go to Herbivore island.
