This is a very useful mount, especially in PvP. It has a special jump attack, which can grab players and hold them, or knock them of their mounts. It doesn't have much health though. It is fast on land and in the water, however increasing movement speed doesn't affect swimming speed.
These tames are good to defend your base leave several on the setting to attack anyone attacking your base because they can jump and dismount attacker I left some on the roof and they picked attackers off there flying tames and my turrets did the rest
They are really good for Trilobites. The pounce means they move very quickly on land and are fast swimmers. Once they grab a Trilobite they walk in a circle with them in there mouth till it dies. No more chasing them across the beaches.
