Astral Mosasaur
Astral Mosasaur Egg & Breeding Calculator
Instead of laying eggs, the Astral Mosasaur carries its young through a gestation period. Gestation takes approximately 8 hours at default rates.
The baby Astral Mosasaur takes approximately 7 days and 17 hours to fully mature at default rates - at a glacially slow pace - plan for a multi-day commitment. During the baby phase (0–10%), hand-feed it directly. From 10% onward (juvenile), it can eat from a Feeding Trough.
Mutations can add +2 levels to any stat and change colors. Stacking mutations across generations is the key to min-maxed breeding lines. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
The Astral Mosasaur's growth progresses through three stages: Baby (0–10%) lasts ~1111 min and requires constant hand-feeding. Juvenile (10–50%) spans ~74h - it can eat from a Trough now. Adolescent (50–100%) takes ~93h - continues eating from troughs, nearly fully grown.
Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Astral Mosasaur gains 30% bonus damage and resistance when ridden by the imprinter. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

Planning a mass raise? The Astral Mosasaur raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~1111 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.
Adjust the dino count to calculate food for multiple Astral Mosasaur babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

During the Baby phase (0-10%), you must hand-feed or use a Maewing to nurse. From Juvenile (10%+), dinos can eat from a Feeding Trough on their own. Use Preserving Salt in troughs to double spoil times.
ARK: Survival Ascended features the Astral Mosasaur as an aquatic, carnivore creature that survivors will encounter in the wild. It falls within the Variant classification.
Its base Melee Damage sits at 100%, giving it decent hitting power. With 54,000 base Health, the Astral Mosasaur is extraordinarily tanky. Stamina sits at 400 base, providing solid stamina reserves. A base Weight of 1300 means massive inventory space.
The Astral Mosasaur roams the ARK as a wild, untamable creature. It gives live birth after a gestation period, making breeding straightforward. Killing a wild Astral Mosasaur yields 3200 base XP. It can be cloned at a Cloning Chamber for 0.88 Element plus 0.01 Element per level.
