Good for farming bio toxin, as it can attack Cnidaria without being stunned or knocking off the rider. Takes damage when it goes too deep, though surfacing rapidly heals it.

Even if you don’t have the saddle Engram for it you can use it as a way to get free oil 😱😱😱😱. Like so low level ppl can see

A great beginner tame, once you have an icthyosaurus, you can swim up to it and passive tame it. I just tamed one, and less than 5 minutes after I tamed a level 4, it’s killed 2 megalodons and 4 mantas. Like so noobs and beach bobs can see.

Good fighter, immune to jellies, supernatural healing boost at the surface, produces oil in its inventory, impervious to squid grabs, looks kinda cute too, only one bad thing about it: it gets squashed in the deep! Only slowly but the damage is there!

Can kill squid like their kin in real life. Tame a 150 and you can take on alphas like they are regular ones. Just up health and memes. They recover steam so quick boosting it is pointless. An all around amazing creature, 10/10.

Oh my god it does not get effected my jellyfish this is one of the best creatures ever.

Mine just ate an alpha mosasaur.

Generally surrounded by what appears to be some sort of coral fern. Coral fern is in fact a swarm of feral majestic sea flap-flaps. Swarm is protective of their oily host.

Reasons to tame a basilo:

1. Water tanks. They can take damage and dish it back out. I killed a moss with mine.

2. Fast health regeneration near surface. Fight any surface predator and barely lose any health

3. Makes oil.

4. Keeps you warm in cold places and cool in warm ones

If you don’t have a basilo, tame a basilo.

King of the sea. A tuso or mosa will do more damage but you can not be knocked off a basil making them essential for underwater caves which are full of jellies, Eels and even tuso's. They are also the perfect size to navigate through them without getting stuck or having to dismount. If you have a Baryonyx they are very easy tames, just use the AoE spin attack to kill all the Manta's and you can passively tame it at your leisure. Combine their oil with organic poly and water in a cooker to make soap which doesn't expire and can be ground back into oil and organic poly when you need it.

From my testing, it seems like one of these generates 20 oil in ~25 minutes, so that’s a rate of 4/5 per minute. You can refine 6 oil into 5 cans of gasoline, so 4/5 oil per minute would equate to 2/3 gasoline per minute. A fabricator burns fuel at a rate of 1 can of gasoline per 15 minutes (1/15 per minute). So basically, with a single basilosaurus of any level, it will produce enough oil to keep 10 fabricators constantly running simultaneously if you constantly collect and refine the oil it produces. Electrical generators burn gas 4 times slower than fabricators do, so a basilosaurus can produce enough oil to simultaneously and constantly power 40 generators. I wish I knew about this before travelling to the iceberg from my base in the south to gather oil : (

One of The most stupidly overpowered water Dino's following Icthyosaurus

1: passive Oil generator (spoils, sadly)

2: high hp and fast regen at surface (lose hp when deep)

3: hypo/hyperthermic insulation when ridden

4: immune to dismount effects and cnidaria stun

5: drops [__]loads of oil when killed, wild or tamed

6: great semi-battle exploration creature

7: saddle unlocks I think before Argentavis

8: little slow, but able to outrun Meg

9; is sea wiener, make human happy

It makes oil with a timer once tamed

Basilos, one of, if not, the best aquatic mount in the game. Not able to be stung by the jellyfish, healing quickly at the surface, and for being a whale for ARK's sake. They have tons of weight, damage, and, best of all, the potential for a MASSIVE health pool. I bred a fully imprinted, non-mutated Basilo for the first time today, and after killing an alpha Meg and Leedsichthys, it has nearly 200,000 health. Damage-wise, it isn't too crazy, but it is especially good for an aquatic mount. The only aquatic creatures to rival the Basilo in its capabilities are the Most and Tuso, and possibly the Plesio as well. The Miss was the original King of the Sea, but ever since Jellyfish were added, they have been in a fire need for a TLC. The Plesio is fast, but it doesn't do as much damage and is not as manuverable as the Basilo. That leaves the Tuso. It has a long reach, but Basilos are not affected by its grip. This truly proves they are the King of the Ocean.

I use my 170 basilosaurus to kill the alpha mosasaurus (level 50+) mine has 30k health. I bite until half health, rise all the way to the surface and continue until the mosa is dead. Health rises so fast at the surface!

The health regen on these things is insane. Keep fights near the surface and avoid crush depth for best results.

This will be your best ocean mount due to the fact that it can not be shocked by the eels and Cnidaria,cant be grabbed by a tuso,regens health very fast on rhe surface,and many other uses.

When they eat they produce oil...

This is the only sea mount you should currently use for adventuring or the underwater caves. High levels easily tear through alphas and other hard to kill creatures like squids or mosas without the fear of dismounting due to squids or eels or jellyfish.

Do not be almarmed by it taking damage in deep water, its very small and takes a long time to kill your whale and can easily be healed by surfacing. The underwater caves have pockets you can surface at to heal. The surface healing can out-heal almost all wild dino damage and a lot of the cave damage. Fight at the surface if you can.

They also generate oil over time. They can only carry 20 oil at a time though so make sure you empty it often. The oil also spoils so use it quickly.

You can also press left trigger at the surface to jump and spray water. Careful not to beach your whale in the process though.

A basilosaurus is able to ignore a jelly-fish sting, disregard the grab of a tuso, and makes oil. Careful, everything arggos these dudes for no reason.
