Get a Pair of high level ones and breed them.
You will end up with an army in no time and these little suckers will shred anything, even alpha karkinos or basilisks on aberration are hillariously easy to kill. And you can farm trilobites just pouncing up and down the rivers with a pack in tow. Just hit one and your pack will finish the job and remember to use the packs hunting call
This is great for taming other small creatures, because of it's pounce ability you can pounce small creatures such as sabertooths, direwolfs and terror birds without getting damage a little...if you pounce an creature then use your crossbow to tranq them
