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!
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 : (
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.
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.
A little fact: If you have a basil and you are in the ocean and got dismounted from your mount (like an ichy) and you have a tamed basil with you , make him follow you and swim directly to the surface.The basil will follow you and push you up wards (if it doesn't, just make it swim close to the surface and just swim/climb onto its back) your welcome! :)
