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.

The females are pure speed. They can't attack, however they can jump really far. I've had a few die that way. The males however, they sent as fast, still have the super jump. But they are the best thing to ever use for thatch gathering. Its worth it to get this as soon as you can.
