Eurypterid Egg & Breeding Calculator

Full maturation from baby to adult takes ~3 days and 20 hours (1x rate), progressing 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.

Offspring inherit parental stats and have a small chance to mutate, gaining +2 levels in a random stat. Use the breeding calculator to plan food requirements, incubation timers, and maturation phases.

The dinosaur is in its mother's womb, requiring time and care from the mother for successful gestation and birth.

The hatched dinosaur, now a baby, needs constant attention and food placed directly in its inventory to survive, or a nearby Maewing to take care of its needs.

Juvenile

10% - 50%

37:02:13

The dinosaur reaches the juvenile stage, where it can now eat from a feeding trough, reducing the need for direct feeding.

Adolescent

50% - 100%

46:17:46

The dinosaur reaches the adolescent stage, becoming more independent and able to follow you while continuing to grow toward full maturity.

Maturation has three phases: Baby (0–10%) lasts ~556 min and requires constant hand-feeding. Juvenile (10–50%) spans ~37h - it can eat from a Trough now. Adolescent (50–100%) takes ~46h - continues eating from troughs, nearly fully grown.

Don't skip imprinting - each successful imprint boosts the Eurypterid's stats, and hitting 100% grants a 30% combat bonus when the imprinter rides it. Keep various kibble types on hand, as imprint requests are randomized between cuddles, walks, and kibble feeding.

Use the raising calculator to plan food requirements for raising Eurypterid babies through all three growth stages. Budget ~556 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.

Adjust the dino count to calculate food for multiple Eurypterid babies at once - essential for batch breeding operations. Consider food spoilage when choosing what to feed: Kibble lasts days, while Raw Meat spoils in minutes.

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.

Found throughout the ARKs, the Eurypterid is an aquatic, herbivore creature in ARK: Survival Ascended.

Dealing 100% base Melee Damage, the Eurypterid brings decent hitting power to the table. Starting at 160 Health, it's relatively fragile. Stamina sits at 100 base, providing limited endurance. Weight capacity starts at 150, giving it average weight tolerance.

The Eurypterid is a wild creature that cannot be tamed through conventional methods. Defeating one in the wild grants 1 base XP. It can be cloned at a Cloning Chamber for 0 Element plus 0 Element per level.
