Castoroides
Castoroides Egg & Breeding Calculator
The Castoroides gives live birth after mating, skipping the egg-incubation step entirely. Gestation takes approximately 8 hours at default rates.
The baby Castoroides takes approximately 2 days and 13 hours to fully mature at default rates - over a lengthy period. The most labor-intensive part is the baby phase (0–10% maturation) when it can't use a Feeding Trough yet.
Each baby inherits stats from both parents with a chance of mutation - +2 wild levels to a random stat plus a color change. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.
Raising a baby Castoroides involves three maturation phases: Baby (0–10%) lasts ~370 min and requires constant hand-feeding. Juvenile (10–50%) spans ~25h - it can eat from a Trough now. Adolescent (50–100%) takes ~31h - continues eating from troughs, nearly fully grown.
Imprinting during maturation provides permanent stat bonuses. At 100% imprint, the Castoroides gains 30% bonus damage and resistance when ridden by the imprinter. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

The raising calculator above shows exactly how much food you need for each maturation phase of the Castoroides. Expect ~370 minutes of active care during the Baby phase before it graduates to trough-feeding as a Juvenile.
The multiplier feature helps plan large-scale Castoroides raises by totaling food across all babies. Different food types have different spoil timers - factor that into which food you stockpile.

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.
The Castoroides is a tamable, herbivore creature in ARK: Survival Ascended. Classified under the Farmer group.
With 180 base Stamina, the Castoroides has decent staying power. Melee starts at 100% - solid damage output that scales with level-ups. Health-wise, the Castoroides sits at 450 base, making it reasonably durable. It carries 300 base Weight - generous inventory space.
The Castoroides is a knockout tame: apply enough torpor to knock it out, then place food in its inventory. For best results, use Superior Kibble - it gives the highest taming efficiency.
As a tame, the Castoroides earns its keep through resource gathering, making tedious farming runs much faster. It gives live birth after a gestation period, making breeding straightforward. Defeating one in the wild grants 4 base XP. It can be cloned at a Cloning Chamber for 0.84 Element plus 0.01 Element per level.
