Basilosaurus are passive-tamed by feeding them meat or preferred kibble, but their surrounding mantas, sharks, and other threats should be cleared first. Stay nearby to protect the tame, as feeding intervals can be lengthy, and use the same food consistently. As powerful ocean mounts, they resist jellyfish and eel stuns, reduce dismounting risks, carry considerable weight, provide insulation, regenerate health near the surface, and produce oil, though deep water harms them.
