Knockout tame. Edit the Use column to mix foods — the game eats the best food first, so the summary feeds your kibble/prime before filling the rest with meat. Sedatives shown keep it under for the whole tame; bring spares.
Minimum to knock out
| Weapon | Min. hits | Torpor / hit |
|---|---|---|
 Tranq Arrow (Bow) | 332 | 90 |
 Tranq Arrow (Compound Bow) | 246 | 121.5 |
 Tranq Arrow (Crossbow) | 190 | 157.5 |
 Tranq Dart (Longneck Rifle) | 135 | 221 |
 Shocking Tranq Dart (Longneck) | 68 | 442 |
Minimum hits to knock out a level 150 Ocean Mosasaurus, using primitive (100%-quality) weapons. This is a floor — it ignores the torpor a creature regenerates between shots, so bring a few spare. Land hits on the head where possible for bonus damage, and watch torpor doesn't drain faster than you raise it.

Forward calculator. Enter the wild points a creature rolled (and domesticated points you spend after taming) to get each stat's value. Uses official-server rates with no imprint bonus. Melee and movement speed are shown as a percentage; taming effectiveness only boosts stats with a taming bonus (such as melee).

Raising. The Baby phase (0–10%) is the dangerous window — the baby can't eat from a feeding trough and must be hand-fed until it reaches Juvenile. Imprint at each cuddle interval for the full bonus. Wall-clock times assume the egg is fertilized now and rescale with your server profile; mating cooldown is unaffected. Imprint counts assume the default imprint amount — tune that on the imprint calculator.

Percentages are the odds of each pick within its loot set, not a guaranteed per-kill rate — a kill can roll a set several times.
Ocean Mosasaurus guide
The Ocean Mosasaurus is a carnivore in ARK: Survival Ascended. This page covers its spawn commands, base stats, taming and breeding — with interactive calculators you can drive by level.
How to tame the Ocean Mosasaurus
The Ocean Mosasaurus is a knockout (violent) tame. Render it unconscious with tranquilizer arrows or darts, then feed it raw meat — with raw prime meat, cooked meat or its preferred kibble taming faster and keeping effectiveness higher. Keep its Torpor topped up with Narcotics or Narcoberries while it eats — use the taming calculator above to see exact food counts, taming time and the effectiveness you'll land at your target level.
Aim for the head where you can — most creatures take extra torpor from headshots — and don't let Torpor drain faster than you raise it. The knockout estimator above lists the minimum tranq arrows and darts for any level.
Ocean Mosasaurus spawn command
To spawn a wild Ocean Mosasaurus, open the console and run its Summon command. To spawn one already tamed at a chosen level, use GMSummon instead — both are copy-ready in the Spawn commands panel above, along with the raw spawn class (Ocean_Mosa_Character_BP_C) for use with commands like SpawnDino.
