All you need is a good pike, get pulled off your mount and poke this little f***er to death. If you are going for taming, bring a Mastercraft or ascendant crossbow, only takes about 5 narc arrows for a level 115.
Kaprosuchus
The Kaprosuchus is a crocodile-like reptile commonly found around swamps. Though it is a smaller, weaker version of the Sarco, some survivors perfer it for its speed — both on land and in water.

Player-written tips for taming, using, and fighting the Kaprosuchus in ARK: Survival Ascended & Evolved.
Careful when in swamps and using smaller mounts it will superman outta nowhere and drag you away into the water.
If you're on Scorched Earth riding a wolf, these guys are your worst nightmare. One took me off of my mount and ricoched to the top limit barrier of the map. Punched it to death falling and landed in a puddle to survive.
When you put he in a taming cage you have to make the wall 2 high because he can climb over 1 high wall
Don't go in the swamps with medium size tames, no matter the lvl. These things you take you out of your mount, kill you and team up with titanoboas, baryonix and sarco to kill your tame. I lost a 156 lvl sabertooth this way and almost lost my 204 lvl frog.
If it happens to grab you and you have enough points in health and melee damage then you can knock it out while in its teeth.
My Kapros food didn't start at 2100 rather it was 1200 base...
To tame just punch him out when he picks you off of your tame on the swamp
I accidentally knocked mine out with my fists. I am level 65 and have a leveled my melee up a lot. I almost died so this definitely not the best method.
The bola doesn't seem to hold them. I used the bola on one it stopped for a few seconds than lunged while the bola was still on it and proceeded to munch my bones into paste.
These guys are a pain. Flying around on my argy in the swamp and bam out of nowhere one takes me off my mount and kills me.
Let them get you then punch shoot just tranq them when they grab you:)
Definitely will surprise attack you. One of these guys got me in it's mouth so I started shooting at it with arrows and got him to pass out before killing me. See it before it sees you!
This thing is ruthless. It grabbed me when I was at the swamp at the center, it Michael Jordan jumped me?
Dont ask “where is it“ or it will jump from up to 30 meters away directly in your face, take you and jump away again and eat you somewhere other. Search a high stone, shot it from distannce and wait until it jumpes away from the stone again.
If you get grabbed by one just pike it in the face, I killed 4 of them in primitive flak and with an apprentice pike. They aren't that strong
Try to let it grab you and then bola it bc it will hit 100% of the time. Then light him up with some darts. Its is a qick tame if u ate still in tje swamp just back peddle on sarcos and snakes for prime. Took me only 40 min for a 150
These spawn around the red obelisk on scorched earth. When at the obelisk they can jump out and grab you. Be careful when there.
The trick is not to panic these guys are really easy to kill. Just keep a pike with you and if one grabbed you kill it as soon and as fast as you can.
Can now only pick up small to medium dinosaurs on paper only
