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!
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.
