How to Tame a Sarco in ARK

The Sarcosuchus — "Sarco" for short — is ark.wiki.gg's own "medium-sized, carnivorous reptile known for its high swimming speed and ability to near-instantly replenish its Stamina while in the water," and its name literally translates to "Flesh Crocodile." This guide covers exactly what the wiki documents: how the knockout taming method works on a Sarco, which food and kibble it prefers, how torpidity math scales from Level 1 to Level 150, and what you get once it's tamed — base stats, combat abilities, and where it actually lives. Anywhere the source doesn't give a clean figure, this guide says so instead of guessing.
Meet the Sarco: A Knockout Tame With Instant Stamina Regen
The infobox lists the Sarco as group Reptiles, species Sarcosuchus excubitor, time period Early Cretaceous, diet Carnivore. The page gives two different temperament fields that don't fully agree: the general temperament field says Patient, while a separate temperamentReal field says Aggressive — the source doesn't reconcile the two, so both are reported here. The Domestication table confirms it is Tameable: Yes, Rideable: Yes (Swimming), Breedable: Yes, Torpor Immune: No, tamed via the Knockout method.
For the KO itself, the wiki's strategy section is explicit: "use Tranquilizer Arrow, Tranquilizer Dart, a Wooden Club or the Slingshot (Not effective on high level creatures)... A good strategy for knocking out a Sarco is to first clear out the area of dangerous creatures, then make sure it is on land (they flee extremely quickly in water), and eventually find a tall rock you can stand on and begin firing darts/arrows." The Dossier adds: "a patient killing machine... it is not opposed to scurrying onto land and pressing the issue when hungry."
Best Taming Food and the Regular Kibble Recipe

The Domestication table names the Preferred Food as Raw Prime Fish Meat, and lists two separate Preferred Kibble entries: Regular Kibble and Kibble (Trike Egg). The page doesn't say which outranks the other, so treat both as documented options rather than a ranked pair.
Regular Kibble's own recipe, per the wiki: 1× Cooked Meat Jerky, 1× Medium Egg, 5× Fiber, 2× Longrass, 2× Savoroot, 1× Water — six ingredient types totaling 1+1+5+2+2+1 = 12 individual items per craft. The taming-food table also lists Raw Mutton, Raw Prime Meat, Cooked Lamb Chop, and several more meat tiers with exact quantities and feed times per level, but no stated taming-effectiveness percentage between tiers — so this guide doesn't put a number on "how much worse" a lower tier is, just that it costs more of it.
Torpidity and Tranq Math: Why Higher Levels Take Far Longer

The wiki's taming table gives, per level, six unlabeled KO shot counts (the numbers are listed without saying which specific weapon each belongs to, so this guide won't guess a mapping) plus a torpidity depletion rate and a time-to-fully-deplete. At Level 1: counts are 40/17/5/3/2/1, depletion 0.3 torpor/s, fully gone in 00:22:13. At Level 60: counts are 182/75/21/12/9/5, depletion 0.66/s, gone in 00:46:32. At Level 150: counts are 398/163/45/26/18/9, depletion 1.04/s, gone in 01:04:01.
The arithmetic: the top shot-count figure grows from 40 at Level 1 to 398 at Level 150 — roughly 10x (398 ÷ 40 ≈ 9.95). The depletion rate more than triples over the same range (1.04 ÷ 0.3 ≈ 3.5x), meaning a Level 150 Sarco needs far more shots and loses torpidity faster once you stop shooting — a much tighter window to finish the knockout.
Base Stats, Abilities, and Where Sarcos Live

Base stats at Level 1, base value and per-level increase only (the table's taming-bonus/multiplier columns were inconsistently populated in the source, so those are left undocumented): Health 400 (+80/level), Stamina 450 (+45/level), Food 1500 (+150/level), Weight 300 (+6/level), Melee Damage 35/45 (+1.75/+2.25 per level), Torpidity 400 (+24/level). Oxygen is N/A. Movement lists a walking base speed of 150 u/s and a swimming base speed of 750 u/s — five times faster in water (750 ÷ 150 = 5) — with several tamed/sprint columns literally marked "?" in the source itself.
Its four ASA abilities, ranked by stated damage: Death Roll (45 damage, every 2.25s, grabs small/medium creatures and Humans), Leap (40 damage, every 0.44s), Bite (35 damage, every 1.85s, doubles attack speed while swimming), and Surprise Bite (35 damage, every 1.27s, needs a 90°+ side/rear aim). Passives: it scares Piranhas while swimming, is ignored by Leeches unless it attacks first, and regenerates Stamina near-instantly while still and swimming. Head hits carry a ×1.5 damage multiplier, and on ASA that multiplier also applies to the player's own melee attacks.
Habitat spans The Island, The Center, Ragnarok, Extinction, Valguero, Genesis: Part 1, Crystal Isles, Genesis: Part 2, Lost Island, Fjordur, Midgard, and Vanaheim, with the Aberrant Sarco variant also on Aberration; the page's common/rare/cave rarity legend didn't survive extraction cleanly, so this guide can't say which map has which rarity. The Sarco Saddle unlocks at Level 35, a kill grants 20 XP per the Data table (the infobox separately lists a basexp of 5 — the two aren't reconciled by the source), Drag Weight is 200, and Death Roll can grab a documented list of 33 creatures, including Compy, Dodo, Raptor, Troodon, Mesopithecus, and Human.
Get it on land before you shoot: Sarcos flee into water almost instantly, and the wiki notes they're actually faster swimmers than they are land-walkers, so one that reaches deep water is one you've lost for now. Clear nearby threats first, find a tall rock for a clean firing line, and load Raw Prime Fish Meat or Regular Kibble into its inventory the moment it's out.
Running your own ARK server
Chasing a Sarco through swamp water only to lose your trap setup to a server restart is exactly the kind of run a private server avoids. A dedicated ARK server keeps your tranq stockpile, your fish-meat supply, and your half-tamed Sarco exactly where you left them, with no random players interrupting a Level 150 knockout mid-fight.
Conclusion
Taming a Sarco comes down to what the wiki documents: knock it out on land with Tranq Arrows, Darts, or a Wooden Club, feed it Raw Prime Fish Meat or Regular Kibble once it's under, and expect the fight to get dramatically harder at higher levels — a Level 150 needs roughly 10x the top-tier shot count of a Level 1 and burns through torpidity 3.5x faster. Once it's yours, a Level 35 saddle unlocks a 750 u/s swimmer with a 45-damage Death Roll and near-instant stamina regen. Rarity-by-map data, the taming-bonus columns, and the weapon-to-shot-count labels weren't in the source and aren't guessed here.
