These thing are so good for oil while killing them gives more but taming them will passively make oil for you
Basilosaurus
The Basilosaurus is a dolphin-like creature that primarily dwells along the shallow areas of the ocean. It has the ability to keep survivors warm or cool.

What ARK players use the Basilosaurus for, and how to get the most out of it in ARK: Survival Ascended & Evolved.
When tamed it passively generates a natural version of oil that slowly spoils, unlike normal oil. Also, it can only generate up to 20 oil until you take the oil out of its inventory, then it will continue to generate oil. I’m on console by the way, not sure about mobile.
They produce a type of oil that decays over time. It can be refined like normal oil still
You want to tame one of these. I got a 145 one and when it was tamed it leveled to 217, now it has 50k hp. Plus they gather oil like the dunkel
The best aquatic tame second only to the gaint squid.
They are completely immune to jellyfish and eels and can rapidly regenerate health near the surface of the water, combined with an enormous health pool and good attack… Well you can honestly ignore Mosas and Plesis if…

This is a must have tame! Why? Well lemme tell you!
1:they are a really easy tame since there passive tamed so an easy noob tame
2:they are able to withstand a eel or jelly zap so you don’t get knocked of your mount(unlike the lucky noobs…RIP)
3:they are a passive oil…

3:they are a passive oil generator so you get free oil from them,the max they can hold in there inventory is 20 but they produce quickly
4:they have enormous attack damage so you could easily kill a meg(I have a lvl 23-4 or some thing and it kills things in seconds)
5:they have short but good bursts of speed that can get you to the surface in a couple of secs
6:they have an ok saddle?(it’s unlocked at lvl 60 and requires smithy to make)but it lets you ride your helpful tame so…🤷🏻♀️
7:they are chonky so they are pretty cute and come in very colorful colors(lol)
8:they’re health can go very high(like I said before mine is lvl 23 or something and it’s health is over thirteen thousand health so it can take a lot of damage)
9:they are able to keep you from getting to cold or hot(pretty helpful when your in the Arctic region or deep see diving)
10:they need lots of fish meat to be able to get around(they big chungus(I named mine BC))
I hope this helps you with all the tips and time I put into this👍
When killed with dunk they give over 300 oil and only prime meat with over 100 hide too
The true king of the sea can kill anything if high level don’t go to deep or you will take damage kill other whales so you can get like 200 oil
This guy is Super GOOD mount underwater!!
Yes...when u go to deep water it will take a little bit damage..but it slow damage..
It hp is op..and same with attack
IF YOU'RE LOOKING FOR BIO TOXIN THE BASILOSAURUS IS WHAT YOU NEED:
They are immune to jellyfishes, they have the ability to keep you warm or cold. But they cannot go very deep in the ocean before starting to get damage from water pressure.
This guy is a beast when collecting meat and fish meat and don’t forget that good biotoxin!
These guys are OP, a decent level can rekt an alpha mosa
Good source of oil if you hate the ocean. Just tame around 3 and have them by the shore, they will have oil in their invo, really quick too. Just take the oil and quickly use it, it spoils after a while
My tribe used the basilo for bringing materials to area far away into ocean with the help of baryonyx we we then able to build a floating city on the water
Basilo good for weight health and damage
I just tamed one and now I have slow but unlimited supply of oil
If you want a lot of oil you can just tame 4-5 of these guys they are easy to tame
Tanks they tank. If you boosted hp a lot then your set. Also they and a good dps to and a oil farm.
These babies right here are like heaters, if u wanna have a nice big buddy share their warmth, this Dino is for u.
DO NOT GO TO THE BOTTOM OF THE OCEAN WHEN INFINITESTATS IS ON because it will instantly die when you go to the bottom of the ocean because it has a crush depth
Trust me, as good as the mosa and the plesiosaur looks, the basi is better don’t waste your time taming trashy tames
The regen is insane the abilities are insane(being able to disregard any ocean critters specil attacks) and its stam is great
