Super fast and annoying, just trap with dino gates and it’s an easy tame

These guys have X variants on genesis 1 and they have high torpor so be prepared. To tame them i suggest using a bloodstalker or a basilo that can tank some damage. If you using a bloodstalker stay on water surface and shoot tranqs, when it swims away go underwater and use your crossbow or harpoon. If you use basilo just let it tank it and shoot it with crossbow or harpoon. But be careful about them attacking you cuz these guys are no joke. They usually have a friend near them so you might have to kill the other one in order to tame the you want. When tamed these guys have pretty high damage scaling but lower hp. They have second attack which does bleed damage(scales with damage, wilds also have this attack) they are fast battle creatures and they have pack bonus just like megalodons so get yourself 5-6 xiphactinus and do the hunt missions with them. Hope this helps

These are pretty easy to tame, I didn’t even trap one I just had one attack my basilo near the shore and they don’t torpor run so that’s helpful.
