How to Tame a Mosasaurus in ARK

 

    The Mosasaurus is one of ARK's deep-ocean apex predators, and ark.wiki.gg is explicit about the scale of the job: taming a Mosasaur requires "the second largest amount of food of any carnivore creature in the game, much more than a Quetzal, and more than double the amount of any other Apex Predator, including the Giganotosaurus." This guide covers the knockout method the wiki documents, the food that shortens the process, how feed time and torpor drain scale from Level 1 to Level 150, and the saddle levels and base stats you're taming toward. Every figure below is quoted or computed from that page; where the source doesn't give a number, this guide says so instead of guessing.

 

The Knockout (KO) Taming Method

 

    The wiki's infobox lists the Mosasaurus as Group: Reptiles, Diet: Carnivore, Temperament: Aggressive, and its domestication section states the Taming Method as Knockout, with Tameable, Rideable, and Breedable all marked Yes and Torpor Immune marked No. Rider Weaponry is listed as No. The source's own strategy notes are worth quoting directly: "As with other starve-taming, be sure to wait until the torpor level drops and feed narcotics or narcoberries in bulk to keep the Torpor level rising till the max before starting to fall again." The domestication block also lists a "Preferred Kibble"/"Preferred Food" pairing twice in slightly different wording (Exceptional Kibble / Kibble (Quetzal Egg) for kibble, Raw Mutton / Raw Prime Meat for food) without clearly separating the two entries — this guide treats the page's dedicated "Preferred Food" list, quoted in full below, as the cleaner source for its preferred foods.

 

Best Food for Taming a Mosasaurus

 

 

    The wiki's dedicated "Preferred Food" section lists, in this order: Exceptional Kibble, Raw Mutton, Raw Prime Meat, Raw Meat. Exceptional Kibble is crafted from "1 × Extra Large Egg, 5 × Fiber, 1 × Focal Chili, 10 × Mejoberry, 1 × Rare Flower, 1 × Water," quoted exactly as listed. The Level 1 taming table shows the gap in raw quantity needed: Exceptional Kibble needs 6 units at Level 1, while the lowest-ranked option on the full table, Cooked Fish Meat, needs 290 — a difference of 290 − 6 = 284 more units of the weakest food versus the top kibble at the same level. The source doesn't spell out what the table's other columns (beyond quantity and total feeding time) measure, so this guide doesn't assign meaning to those figures.

 

Taming Time and Torpidity by Level

 

 

    The wiki breaks the taming table out by six specific levels only — 1, 30, 60, 90, 120, and 150. For Exceptional Kibble, both feeding time and torpidity-depletion time climb steadily with level: Level 1 takes 0:05:56 to feed, with torpidity fully depleting in 00:03:54; Level 150 takes 0:45:24 to feed, with torpidity depleting in 00:11:15. The arithmetic on that depletion window: 00:11:15 (675 seconds) − 00:03:54 (234 seconds) = 441 seconds, about 7 minutes 21 seconds longer before a Level 150 Mosasaur's torpor fully drains versus a Level 1 one — the real reason higher-level tames need more tranquilizer reserves, not just more food. Each level block also lists a bare "KO" line of six numbers (Level 1: × 300, × 123, × 34, × 20, × 14, × 7). The scraped page text doesn't label which tool or substance each number corresponds to, so this guide does not map them to specific weapons or items — treat them as undocumented.

 

Saddle Levels, Base Stats, and Habitat

 

 

    Equipment on the page: Mosasaur Saddle (Level 78), Mosasaur Platform Saddle (Level 93), and a Mosasaur Tek Saddle with no unlock level given — that figure is undocumented and isn't guessed here. Base stats from the growth table: Health 3600 (+432/level), Stamina 400 (+40/level), Oxygen 150 (+15/level), Food 8000 (+800/level), Weight 1300 (+26/level), Melee Damage 100 (+5/level), Torpidity 3000 (+180/level). Taming-bonus percentages appear next to several rows (4.2% on Health, 10% on Food), but the source's column layout doesn't cleanly separate wild versus tamed bonuses, so this guide reports base/per-level figures only. Drag Weight is 899, kill XP is 60, and the Mosasaurus produces no Feces. It can be Carried By a Tusoteuthis and Can Damage Thatch, Greenhouse, and Wood.

 

    Reproduction timers, quoted directly: Gestation 7h 56m 11.428s, Baby Time 18h 31m 6.667s, Juvenile Time 3d 2h 4m 26.667s, Adolescent Time 3d 20h 35m 33.334s, Breeding Interval 18h – 2d. The page lists Total Maturation Time as 7d 17h 11m 6.667s; adding Baby + Juvenile + Adolescent in seconds confirms it: 66,666.667s + 266,666.667s + 333,333.334s = 666,666.668s, which converts to 7 days, 17 hours, 11 minutes, 6.668 seconds — matching the source within rounding, showing Gestation runs separately before the maturation clock starts. The habitat list names Mosasaurus/X-Mosasaurus on The Island, The Center, Ragnarok, Valguero, Crystal Isles, Genesis: Part 2, Lost Island, Fjordur, Midgard, and Genesis: Part 1; the source tags some maps Common/Rare/Untameable/Cave but doesn't cleanly attach each tag to a map in the scraped text, so this guide lists the maps without repeating that tagging. For an easy-taming spot: "Located at the approximate coordinates 27-57, there is an underground lake that overlaps with the X-Mosasaur spawning region."

 

Use a Plesiosaur to scout, then lure the Mosasaur into a water cave and shoot it there — "the bow/slingshot cannot be used under water so a crossbow is required." With 120–130% movement speed and flippers, you can kite a Mosasaurus thanks to its large turning radius. For a fixed trap, the wiki describes "four Behemoth Stone Dinosaur Gateways in a row, with two Behemoth Reinforced Dinosaur Gates set in the front and back," built deep enough that the Mosa won't lose aggro, with gaps wide enough for a smaller water mount like a Sarco or Ichthy to slip through while you close the gate behind you.

 

Running your own ARK server

 

    Taming a Mosasaur is a multi-hour commitment — the Level 150 feeding window alone runs 45+ minutes on Exceptional Kibble, before the crossbow work to knock it out in the first place. A private, always-on ARK server keeps your cage, stockpiled kibble, and half-tamed Mosasaur exactly where you left them if you log off mid-tame, with no risk of another tribe griefing your trap on a public server.

 

Conclusion

 

    Taming a Mosasaurus in ARK comes down to what ark.wiki.gg actually documents: it's a Knockout tame that needs more food than almost anything else in the game, Exceptional Kibble and Raw Mutton are the preferred foods, feed time climbs steeply toward higher levels (Level 150's Exceptional Kibble window alone runs about 45 minutes), and the first saddle unlocks at Level 78. What the source doesn't spell out — the unlabeled six-number KO lists, the Tek Saddle's unlock level, and how the base-stat taming-bonus columns divide between wild and tamed — is left undocumented rather than guessed.
