ARK's base taming speed on PC, PS4, and Xbox is now doubled, meaning 1× is as fast as what 2× was previously. Dododex has been updated to reflect this. Use the "presets" dropdown for common multipliers.

When people say, ‘ughghhugh, these SUCK.’ They are right, and that is sad. These are meant to be of the REX of the sea. (mosa is the giga) intstead, you can outrun them with and ithcy, kill them with a cross bow, and they are just plain BAD. These should be AT LEAST 5x their current size, and their bite is supposed to be one of the strongest in the world. These should be respected by the devs. Like so that this will be fixed.
Megalodon prefer raw meat than raw fish meat, so don't try to kill water dinos to tame your megalodon. In low level, they have low weight, but if you increase its weight, it will be perfect. Megalodon always spawn near red obelisk, so go to the ocean and you will find a lot of megalodon. Remember: If you don't tranquilizater darts, use a crossbow and shoot tranq!
