Regens health fast near the surface.

Gradually loses health when deep.

Passive oil generator.

Immune to electrophorus and Cnidaria stun and dismount effects.

Cannot be grabbed by tusoteuthis.

Passive Tame.

Whoever said riding water tame keeps water creatures from attacking is a big fat lying liar face.

Ride dolphin or manta, water creature won't attack you while riding a water dino, then go near basilo feed it, Don't unride or you'll see your self dying, put food on your hot bar then click it when near basilo u can feed basilo without unriding. Up! So no noobs will be eaten by manta or megalodon lol

When taming this, be careful, Mantas and sharks follows a basilosaurus around and will attack you if you approach or feed the basilosaurus. According to the Basilosaurus dossier, Mantas usually follow them because of their eating habits (Well very messy) and it leaves plenty of leftovers for them. They attack you when you feed a basilosaurus because it leaves no leftovers for them.

I believe the dossier, but yeah.

Click the arrow pointing to the sky if useful, thanks 😊 (Sorry for the dossier spoiler)

In crystal isles, these guys spawn in the tropical beach area in the southwest of map, it’s not common, but they can.

It is like diving with a guarantee. Nothing will scare you even if you have a low level of these beasts. Dont get too attached only danger is starving down there as you cant eat.

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.

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

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.

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!
