I have tamed one whale (in wild it had 125 level) in ARK:Mobile with common meat, prime meat (it was near the Deadly island with big populations of carnotaurs and argentavises) and special balm. With me were baryonyx and ichthiosaurus. I have stunned rays with baryonyx and kill them all, and after this I was feeding the whale.
Now, I have an 208lvl basilosaurus and it is imbalance! I'm fighting off megalodons, I'm sinking mosasaurs! Giant squid? Bash it! Jellyfishes and electrophoruses? Smash it! Alpha predators? Crush it! 23,600 - health, 1500 - stamina, over 200 - basic damage, and near the surface its health regenerates very quickly. The coolest underwater animal for me!
P.S. sorry for grammar mistakes, I'm russian.
More Basilosaurus Utility Tips
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.
