If ure are planning to imprint this guy, from my experience get 3 of ur dinos filled with meat the babies eat A LOT It ate 1 stack in 30 to 40 seconds

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

Clear all hostile dinos like mantas and megalodons then follow it around on a water Dino and feed it with your hotbar

He’s a good guy but he hangs out with a rough crowd.

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

Kill all the mantas with a baryonix and feed it meat when its hungry. Easy but op underwater tame. Hope i helped someone

Pro Tip: Basi’s won’t spawn with a whole gang of mantas on Gen 1 map, making it much easier to tame. You also have increased oxygen and swim speed in Gen 1’s Ocean Biome so you won’t need scuba gear and you can outswim Megalodons easily.

When you feed the basilosaurus yo will notice “Red mist” come from its mouth, this must attracts nearby water carnivores like megalodon to you so be careful and maybe bring some body Guards when taming this thing
