If your going to tame these and your on mobile here’s a few things :)

Go to herbivore island, they spawn there.

You need to tame a ichthy.

If your on a ichthy no mantas will attack you when your around baslios many mantas are to.

I suggest you bring a decent weapon to protect you. Like a sword or some sort of gun just in case,

Very simple tame but only issue is once the Baslio is tamed the whole damn ocean comes after it so get out of there with your baslio quick otherwise you and the baslio will be murdered and after taming one you might wanna build shelter for your sea creatures if you haven’t lol

I have some tips on this guy.

They are good tames, underwater tanks, high inventory space, making you cool in warm places and warm in cold ones, and they produce spoilable oil (if you want oil just kill a wild low level to get lots of oil).

Taming this things is easy, tame a Ichthyosaurus, make a saddle, hop on, go to deep seas (near the herb island is the best), kill a low level one to get raw prime meat, then put it in your tame inventory to make them immune to spoiling for a bit more time.

Find a High level one and tame it, they took their time getting hungry the first time but from the 2 one they get hungry pretty quick.

This guys are very cool, they make a very calming sound, but they have a BIG problem, this things get attacked by any wild thing in water with no reason.

I once got inside of my underwater cave with my Ichthyosaurus and I heard the fight sound track, I came out and saw 10 mantas, 5 megalodones, and 5 electrophorus killing my basilosaurus :(

I lost my 590 oils, 5k hide and 5k fibre and my journeyman’s compound bow :(

R.I.P my level 50 basilosaurus 🪦

Really great creature

Soft skin

cute

Immune to jellies

too fast healing on surface

Okay damage

Passive tame but hard to tame one

Oil produces in inventory

Too good in pvp because of fast healing

Fast

Keeps cool in warm and warm in cold

Thats probably best tame for hunting.

How to tame: Basilosaurus. You will need: Icthy with saddle, a nearby leed and a basilo to tame. Step 1: get on your icthy and scrape meat off the leed until you get prime fish meat. Step 2: find your basilo and put the meat in your hot bar. Step 3: feed meat to the basilo, don't worry, the mantas won't aggro on your icthy. TIP: The interval from 1st to 2nd feed take awhile, but after that it goes pretty quick, so after that interval, be on your guard. Step 4: Keep feeding until it's tamed. TIP: Before you start to passive tame it, bite it once, the mantas will swim away, then start to passive tame, you can still passive tame. Or you can bite it during 1st to 2nd interval. Step 5: there is your very own basilo! lead it back to yoir base and name it.
