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.

Build a raft attach a ballista to the front and re-live the epic tale of moby dick, a-hoy mateys

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.

Ignore posts about taming bar going down, you need to tame it using only the food you give it from the start, if you change the type of food you give it, it then resets the taming bar

It takes a while to eat the second time, so don't fret

Can apparently fight cnidaria without getting electrocuted

It makes oil with a timer once tamed

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.

Seems everything flocks to it mantas and icthy, be careful while swimming near cause they can body block you and you be killed.

If only it had a horn then it could be a narwhal

Take a Baryonyx or a powerful swimming creature to kill off the Manta's and then go in for the tame

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.

To tame the basilosaurus it's a passive tame so kill every thing around it and start feeding it

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.

Is not affected by Cnidaria or electrophorus shocks, this in addition to its surface healing makes it a great mount

It's best to get a baryonyx to stun and kill every manta around it

Rare Flowers affect the Basilo (slightly inconsistently) allowing you to kite it into your own water pen for a super safe, even easier tame involving much less swimming about. Seems to require you to eat at least 2 flowers to trigger the aggro effect, and it loses aggro the second the effect ends.

The one I came across had mantas around it...LOTS. thought I killed em all... Nope. Make extra sure you kill them, and look around a bunch before attempting anything with it
