When taming this, be careful, Mantas and sharks follows a basilosaurus around and will attack you if you approach or feed the basilosaurus. According to the Basilosaurus dossier, Mantas usually follow them because of their eating habits (Well very messy) and it leaves plenty of leftovers for them. They attack you when you feed a basilosaurus because it leaves no leftovers for them.

I believe the dossier, but yeah.

Click the arrow pointing to the sky if useful, thanks 😊 (Sorry for the dossier spoiler)

Tame:

1. Grab an Ichthyosaurus.

2. Put Meat desired by Basilosaurus in your Hot Bar.

3. Ride Ichthyosaurus.

4. Put Basilosaurus-desired Meat Type in Basilosaurus's mouth.

5. Repeat.

6. When tamed, Megalodon/Mantas/Ichthyosauruses-in-wild will follow Basilosaurus.

7. Once Basilosaurus is in a safe spot, Basilosaurus can kill predators.

8. PROTECT ICHTHYOSAURUS FROM CARNAGE!!! I MADE THAT MISTAKE AND REGRETTED IT.

Ride dolphin or manta, water creature won't attack you while riding a water dino, then go near basilo feed it, Don't unride or you'll see your self dying, put food on your hot bar then click it when near basilo u can feed basilo without unriding. Up! So no noobs will be eaten by manta or megalodon lol

How to tame basilosaurus

Where to find:

Basilosaurus are found in the oceans surrounding herbivore Island

Taming details:

Basilosaurus are passive tames that arent aggressive towards you at all and they are carnivores so feed them meat.

Problems:

Basilosaurus are surrounded by mantas and they will attack you when you feed or attack the Basilosaurus, there are plesiosaurs,megalodons,leedsicthis and tusothuthis where the Basilosaurus are,

Advantage:

Basilosaurus are slow so you're underwater mount can keep up with it.

Abilities when tamed:

Basilosaurus are immune to jellyfish stings and eel shocks and cannot be grabbed by squid, they produce oil in there inventory but it spoils, they regenerate health fast near the surrface, they can shoot rainbows out of their blowhole using one of their attacks

Disabilities when tamed:

Basilosaurus lose health when they are in deep water

I find one in shallow water, lagoons, rivers etc. I use my lightning wyvern to kill the mantas as the Basi takes NO shock damage. Flippers and scuba. First feed and wait 5 minutes. Also, kill everything in the area that you can. The Basi likes to wonder while you're taming it.

NEED TO KNOW BEFORE TAMING!

Okay, so I saw one in a river opening on Crystal Isles. I thought the mantas attack you as soon as you go near. So I slowly approached the tail near the river bank. The mantas didn’t agro on me, I thought I was just far enough away. No. Oh no no no noooo. It turns out the mantas ATTACK the second you feed it. Please don’t do what I did haha

P.S I lost my otter to the mantas. R.I.P

This creature is so easy to tame. All you need is:

1. An Ichthyosaurus(these guy won't be attack by any water creature, except the jellyfish)

2. Anykind of meat(I suggest using prime meat and don't use fish meat)

3. Find one of these creature

4. Feed it prime meat(It's a long time between the 1st and the 2nd feed, after the 2nd feed it's fast)

And then you get one of these, just be careful of the megalodons, they will attack right after it is tamed. I hope this is useful for you<3

For Fjordur players:

DON'T USE SANGUINE ELIXIR!!!

It does not work underwater, tame it with 6 kibbles

Fun fact: the first time you feed it, it takes a while. The rest of the time, it’s much faster, don’t worry!

Fun fact I found real useful, I have my base in the herbivore island and there's LOADS of these guys around. I know a lot of ppl say it's hard to tame but reality is (at least for mobile, not sure about pc or console) that if u don't want the mantas to attack, feed the Basi off a back of an aquatic tame. According to the dossier, the mats follow the basi to eat and once a player comes near they see it as a threat. But if another water tame comes it'll ignore, and let u tame the basi. I currently have 3 and I'm only level 41 on solo, very quick to tame, I recommend normal meat over fish meat if Ur a low level just cuz they tame faster for some reason. And what's more to these beasts, I don't have a saddle but at least now I already have access to oil, cuz this guy produces it, making kibbles as easy as ever. Hope it helps and have fun taming Ur basi :)
