On the Island, they can be found near herbivore Island

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!

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.

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

If you are raising a baby keep in mind that their food drops faster than they can eat, so you have to force feed them until their food bar is full or else they will eventually starve to death even with food in their inventory. If you are on singleplayer you can also leave and rejoin your game to make the basilo instantly eat the food in its inventory until the food bar is full or there is no more food in its inventory.

If one spawns 3 mantas will automatically spawn near it, and start following it and group up near its belly. If you feed a basilo every ichthy/megalodon/manta near the basilo will automatically take one damage (the game inflicts the damage as if it was inflicted by you), then get angry at you and start chasing you. You should then run away if your tame can't kill the mantas quickly because mantas do more damage through armor like saddles than other creatures, so your tame's health might get shredded in seconds.

They have 12000 drag weight, the 2nd most in the game along with liopleurodons.

I have a tip to share on how to deal with the Mantas and Megalodons that are surrounding the area where the Basilosaurus roams. Make sure to go with a high level Baryonyx because of its underwater stun ability and damage in general. Make sure to damage one manta so they will all start following you. Then lead them away and kill them. Killing the Megs is easier in my opinion, plus you can gather them all in one place, stun them and start killing them!

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.

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.

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

Bring baryonx it stubs mantas

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

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.

It's best to get a baryonyx to stun and kill every manta around it

Is not affected by Cnidaria or electrophorus shocks, this in addition to its surface healing makes it a great mount
