Usually sorrounder by a bunch of unholy demons of the deep. If you have a bed set up nearby and decent oxygen levels you can just approach, feed then try to get as far away as possible before you get killed,then when you return the bodyguards have usually forgotten their job and started looking for other people to annoy
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
Pro Tip: Basi’s won’t spawn with a whole gang of mantas on Gen 1 map, making it much easier to tame. You also have increased oxygen and swim speed in Gen 1’s Ocean Biome so you won’t need scuba gear and you can outswim Megalodons easily.
When you feed the basilosaurus yo will notice “Red mist” come from its mouth, this must attracts nearby water carnivores like megalodon to you so be careful and maybe bring some body Guards when taming this thing
