Passively generates oil, America might want to come for you and steal it, I recomend hiding

If only it had a horn then it could be a narwhal

On the Island, they can be found near herbivore Island

I read on the Ark Wiki that these guys are actually passive don’t let their size and teeth intimidate you but be warned they are most often accompanied by a flock of Mantas which are annoying

This is the only sea mount you should currently use for adventuring or the underwater caves. High levels easily tear through alphas and other hard to kill creatures like squids or mosas without the fear of dismounting due to squids or eels or jellyfish.

Do not be almarmed by it taking damage in deep water, its very small and takes a long time to kill your whale and can easily be healed by surfacing. The underwater caves have pockets you can surface at to heal. The surface healing can out-heal almost all wild dino damage and a lot of the cave damage. Fight at the surface if you can.

They also generate oil over time. They can only carry 20 oil at a time though so make sure you empty it often. The oil also spoils so use it quickly.

You can also press left trigger at the surface to jump and spray water. Careful not to beach your whale in the process though.

A basilosaurus is able to ignore a jelly-fish sting, disregard the grab of a tuso, and makes oil. Careful, everything arggos these dudes for no reason.

I would take a barryonyx to tame basilosaurus mainly because of the rays.

I keep thinking I hear Lugia. Also this thing kills tusos and alpha megs easy. Only advice for alpha megs is to stay near the surface of the water for healing boost while fighting and when the Meg tries circling to reposition itself just stay where you are and let the stamina be restored. It’s not just the mouth that does damage, it’s the hips too. Might name my next one Shakira!

Sweats oil, attracts water critters, jellyfish slayer, looks adorable. best tame.

But…

DONT USE IT FOR MOSA / PLESI TAMING. mosasaurs and plesiosaurs usually if not only spawn in the abyss and your poor whale sausage will get compressed down there.

Facts. They help you stay warm and cool

They lose hp in the deep

They are passive tames

They are immune to cnidarias and eel stings

For that one guy saying these things are op and you need to nerf them, the ocean is already full of under powered, ultra nerfed creatures that you can tame, like seriously man what are thinking, the ocean is fun but a bunch of animals are weak compared to alphas, and can easily die to electrophorus and cnidara, the basilo is the only exception, so you wanna nerf it.

Never ever get too close when taming on mobile, you’ll get bugged inside of it and drown.

Rare Flowers affect the Basilo (slightly inconsistently) allowing you to kite it into your own water pen for a super safe, even easier tame involving much less swimming about. Seems to require you to eat at least 2 flowers to trigger the aggro effect, and it loses aggro the second the effect ends.

I got lucky and was able to find one of these things without mantas near it in the shallows of Herbivire Island...thank goodness, do not use fish meat!!

For the peeps that asked,

Mantas like the basilos cuz it says in the dossier that they make a mess when eating so mantas are kinda like scavengers that eat the left overs

After the first feed, it will take a long time to want to be fed again. Don’t worry. Just follow it around and keep it safe. After a while, it will want to be fed again and it will progress according to the time intervals on the app.

Do not feed It with meat while on the deeps, It damages instead of healing the basilo, but when at medium depths and on the surface the meat will heal them normally, Upboot If you found this useful, i learned by myself.

So I found this guy at a island where herbivores spawned I had some prime meat I feed it and I tamed it once it is tamed everything attacks it

Bring baryonx it stubs mantas

I tamed mine with a baryonyx to kill the manta bodyguards. The time between the first and second feeding interval takes a while, so sit back and grab some coffee while you wait. Regular meat will do as after the second feeding, the interval is only about 10 seconds. Make sure you keep all Megalodons and other mantas away from it while taming. I absolutely love mine for alpha killing and bio toxin farming. Also they get a crap ton of hit points per level up, almost 400.
