If a cnidaria killed my spino, boy i would be mad. i lost my sarco to cnidarias, a scare with my icthy with cnidarias, and almost got my megalceros killed by some. ( he is dead now D:) I kill any of these that i can. The dossier says that they are passive, but aggresive when approched, NO! as soon as i step in the water these attack, and they litterally don't move at all, they just sit there and chill until you or a tame steps in the water. one like=one prayer for my deceased sarco, Gatorade (you can find his story in sarco) and one member of the cnidaria hate club.
TAME BASILOSAURUS!! They do not affect the Basi at all whether you’re using it as your mount or a follow tame. If mount tame you won’t be shocked or knocked off while killing or if follow tame use it to kill them so they don’t kill you and whatever Dino you’re mounted on.
P.S. just incase so I’m thorough and not misleading any “noobs” or beginners to tame the Basi it’s a “passive tame” or “non-violent” so taming it does not involve knocking it out. Tame an Itchyosaurus(also passive tame but they don’t try to attack you) once you tame the Itchy use it to tame the Basi otherwise the Basi will attack you
