They are basically a mini karkinos in terms of utility you can grab dinos and shoot them off the back of the kapro and also use them to tame bigger dinos but it's hard because kapros are slow and have had health the biggest dino they can grab is raptor
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
It has it's uses in pvp but completely useless in pve with its low damage, low hp, low speed(lower tham Sacro both on land and in water), all it has is high stamina ehich it doesn't even need for it's leap attack and his leap whiffs if the terrain in front is so much as 1cm hugher elevated than your current position
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.
