I always find them around herb island .. best way to tame I found is one guy on an ichty following and feeding it and another guy on a baryonyx or other quick strong water tame to fight off any threats that may interrupt taming
Basilosaurus are found in the oceans surrounding herbivore Island
Basilosaurus are passive tames that arent aggressive towards you at all and they are carnivores so feed them meat.
Basilosaurus are surrounded by mantas and they will attack you when you feed or attack the Basilosaurus, there are plesiosaurs,megalodons,leedsicthis and tusothuthis where the Basilosaurus are,
Basilosaurus are slow so you're underwater mount can keep up with it.
Abilities when tamed:
Basilosaurus are immune to jellyfish stings and eel shocks and cannot be grabbed by squid, they produce oil in there inventory but it spoils, they regenerate health fast near the surrface, they can shoot rainbows out of their blowhole using one of their attacks
Disabilities when tamed:
Basilosaurus lose health when they are in deep water
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
Okay, so I saw one in a river opening on Crystal Isles. I thought the mantas attack you as soon as you go near. So I slowly approached the tail near the river bank. The mantas didn’t agro on me, I thought I was just far enough away. No. Oh no no no noooo. It turns out the mantas ATTACK the second you feed it. Please don’t do what I did haha
