How to Tame a Plesiosaur in ARK

The Plesiosaur — formally "Elasmosaurus remuspissa" on its in-game dossier — is a knockout (KO) tame, and ark.wiki.gg's own strategy notes flag it as one of the harder KO tames because of how fast its torpor drains. The wiki's description: it's "a large, carnivorous reptile living in deep waters, mostly known for its ability to become a small mobile submarine shelter once equipped with its platform saddle." This guide covers what the wiki documents — taming method, food list, torpor-depletion times at six levels, and saddle/stat/breeding numbers — and says so explicitly wherever the source doesn't give a figure.
Taming Method and Preferred Food
The domestication summary lists the Plesiosaur as Tameable: Yes, Rideable: Yes, Breedable: Yes, and Torpor Immune: No — you can knock it out with standard torpor damage. Its taming method is Knockout. Preferred food is split across two kibble entries and two meat entries: "Superior Kibble" and "Kibble (Rex Egg)" both sit under Preferred Kibble, and "Raw Mutton" and "Raw Prime Meat" both sit under Preferred Food — exactly as the wiki lists them, not merged into one item each.
The wiki's strategy text explains the difficulty directly: "Due to their very fast torpor decrease, you need a large amount of narcotics to keep a Plesiosaur unconscious," adding that "bio toxin would be more effective at keeping the creature down," and noting it's at least reachable from Cnidaria given the Plesiosaur's own deep-ocean habitat. Rider Weaponry is listed as No — you can't fire weapons while riding it, though the Platform Saddle allows building turrets on its back. Exact narcotic dosage counts to keep a knocked-out Plesiosaur under aren't given on the source page, so this guide doesn't estimate them.
Taming Foods, in Wiki Table Order

Beyond the two preferred items, the per-level taming-food table lists a full set in this row order, unchanged across every level captured (1, 30, 60, 90, 120, 150): Superior Kibble, Raw Mutton, Cooked Lamb Chop, Raw Prime Meat, Cooked Prime Meat, Raw Prime Fish Meat, Raw Meat, Cooked Prime Fish Meat, Cooked Meat, Raw Fish Meat, Cooked Fish Meat. This is simply the table's row order — the page doesn't label it an efficiency ranking, and this guide isn't calling it one; treat it as "what the wiki lists," with Superior Kibble and Raw Mutton flagged above as the two items actually marked "preferred."
Torpor Depletion Time by Level

The taming table gives a torpidity-depletion rate and a "time until all torpidity is depleted" figure at six levels: Level 1 — 2.14 torpor/s, depletes in 00:12:30; Level 30 — 3.55/s, 00:20:37; Level 60 — 4.63/s, 00:26:11; Level 90 — 5.6/s, 00:30:13; Level 120 — 6.5/s, 00:33:23; Level 150 — 7.37/s, 00:36:00. That's the real taming clock: at Level 150 you get roughly 36 minutes from the moment it goes under before it wakes, versus about 12.5 minutes at Level 1 — higher-level Plesiosaurs are actually more forgiving on time, even though they need more total torpor to knock down in the first place.
The same table also lists six bare "KO" quantities per level (Level 1: 160, 66, 18, 11, 8, 4; Level 150: 1591, 650, 177, 101, 72, 36), presumably one count per weapon/ammo type. The item icons that would identify which figure belongs to which weapon didn't survive the text extraction this article was built from, so this guide isn't mapping any of those six numbers to a specific tool — treat them as undocumented until confirmed against the live page.
Base Stats, Saddle Levels, and Breeding Timers

Base stats at Level 1, wild per-level increase in parentheses: Health 2400 (+288/lvl), Stamina 800 (+80/lvl), Oxygen 150 (+15/lvl), Food 5000 (+500/lvl), Weight 800 (+16/lvl), Melee Damage 75 (+3.75/lvl), Torpidity 1600 (+96/lvl). Bite deals 75 damage, usable every 0.3s by rider or AI; head shots carry a x1.5 multiplier. Equipment unlocks at two levels: the Plesiosaur Saddle at Level 64, and the Plesiosaur Platform Saddle at Level 84.
Breeding timers, quoted from the wiki: Gestation 7h 56m 11.428s, Baby Time 11h 34m 26.667s, Juvenile Time 1d 22h 17m 46.667s, Adolescent Time 2d 9h 52m 13.334s, Total Maturation Time 4d 19h 44m 26.667s, Breeding Interval 18h–2d. Arithmetic on the Juvenile figure so the "1d" doesn't get lost: 1 day 22 hours = 24h + 22h = 46 hours (plus 17m47s). Total Maturation works the same way: 4 days 19 hours = 4×24 + 19 = 115 hours, plus roughly 44 minutes — about 115h 44m egg to adult. On kill: 60 XP, a 100% chance to drop a Fireworks Flaregun Skin, 500 drag weight, no feces. Habitat spans the maps The Island, The Center, Ragnarok, Valguero, Genesis: Part 1, Crystal Isles, Genesis: Part 2, Lost Island, Fjordur, and Midgard — per-map spawn rarity (common/rare/untameable/cave) is marked on the page but didn't survive text extraction, so this guide isn't claiming which map falls into which tier.
Bows and guns don't fire underwater, so bring a crossbow or lure the Plesiosaur toward the surface, where "they seem to lose interest in you when you're near the surface" — letting you take shots and retreat. "If you lure one to an underwater cave, you can stand inside the cave where you can breathe air and tranq it safely." Keep a raft stocked with storage boxes and a bed above your tame spot in case you respawn — but watch for a Leedsichthys, which "can destroy a raft extremely quickly." For combat, the wiki calls the harpoon launcher the best weapon, "as it has the specific purpose of killing/tranquilizing underwater creatures."
Running your own ARK server
Torpor-racing a Plesiosaur at Level 150 means a roughly 36-minute window where nothing can interrupt you — a random restart, a griefer swimming into your fight, or a host reboot mid-tranq can cost the whole attempt and every narcotic you brought. A private ARK server keeps that window entirely yours: your raft, storage boxes, and stockpiled Cnidaria toxin stay exactly where you left them, and your tribe can coordinate the multi-person taming effort the wiki recommends on your own schedule.
Conclusion
Taming a Plesiosaur in ARK comes down to what the wiki documents: it's a Knockout tame, not torpor-immune, preferring Superior Kibble/Kibble (Rex Egg) and Raw Mutton/Raw Prime Meat; torpor drains fast enough that you get as little as 12.5 minutes at Level 1 and up to 36 minutes at Level 150 before it wakes; saddles unlock at Level 64 and 84; and full maturation runs roughly 115h 44m. Narcotic dosages, the six unlabeled "KO" figures, and per-map spawn rarity aren't in the source in a verifiable form, so none of it is guessed here.
