Boy they are fast once tamed. I worry only weight and attack. Always keep fish meat in inventory cause they eat and eat and eat. Ride then in oceans you got a mean machine that devoured everything in sight. Send one after bronto. You get like 500 hide and almost 800 meats including primes.dont forget to cook the prime or it gone forever.... Use these to collect kareatin and criton. To make paste or whatever.
