I got a spino with good hp and dmg plus a little oxygen then attracted the attention of mantas and sharks away fron the basi, then wiped em all out. Next I found something on shore for prime meat to feed it. It definitely helped that it was in a little cove area so no new predators would show up.

Kill off all megs in the area with a fast mount like a sarco, then shoot the basilo with a crossbow. Lead the mantas away (this will take a while) and either kill them or loose aggro. Head back to the whale, give it some kibble (may need 2 or 3 feeds) and now you have a bio toxin gatherer and cave runner! I was completely OK to do this with a lvl 151 sarco with a primitive saddle and a regular set of scuba. I recommend bringing lazarous, and a good crossbow.

For mobile users its a passive tame if you dont know he eat therizinosaur kibble and and it's very slow when it tamed by meat. also it make oil in their inventory but when it get to 20 remove it because it well be so slow. it's powerful and have good health for the sea but it's stamina is bad level up in stamina. thanks for reading

To take this beast, you need to be on a icthy, mantas will flee at the sight of you feeding the creature.

These are the ancestors of the whales guys THATS WHY THEY ARE PASSIVE

The basilosaurus on genisis part 1 usually don’t have mantas following them , and if they do it’s usually 1 or 3. Making them much safer to tame on genisis 1

I saw my first Whale in the bay of Herbivore Island, I was like, hey, it’s a whale, i don’t have any proper sea tames (I had a sarco but that doesnt count) so I got raw prime and fed it that, I ran out of raw prime, Omygod omygod. I used normal raw and the taming bar DIDN’T GO DOWN! So basically I skipped the sharks and Ichthys and went strait for the Basilosaurus. IT IS AWESOME! I highly recommend a whale and they are very common around herbivore island (heck, there’s a new one in the bay now)

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.

Couldn't use the Sangine Elixir at any point during taming, not sure if its because of being underwater prevents you from using the elixir or just the creature.

They’re very useful water tames. Even though taming them is a slight pain (second feed takes forever, but after second feed it eats more often) they’re worth it. They are immune to the jellyfish, they cant get grabbed by tusos, and they provide insulation to the rider.

The best dino to harvest bio toxin.

These thing are so good for oil while killing them gives more but taming them will passively make oil for you

First time I tryed it was killed by megs on the way home second time I had 5 itchys and we made it next to my home but then megs killed all my itchys and the baslio (should have brought my megs too but I did not)

RIP pointy, fast, buddy , new dude, and ,hater (the itchy crew)

Produces oil in it's inventory. Destroys those annoying jellyfish.

When it comes to taming this guy, I personally like to hop on a high level spino. The spino easily deals with anything surrounding the basil, and then go ahead and start feeding it. I use kibble, it's a pretty fast tame, but the time between the first and second feeding feels like forever.

It will start to lose tame bar for some reason and if that happens you may aswell give up :(

The taming interval is actually correct. For some reason ark is buggy so you have to exit render distance like with carcharos. I tested this myself.

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

Always tame these guys riding a dolphin! They hang out with megs and mantas, and they will attack you if you’re not riding a dolphin!
