The Kathreptis reproduces by laying fertilized eggs after mating. Incubation temperature must stay between -75°C and 75°C - use Air Conditioners, Standing Torches, or Dimetrodons to maintain the range. At the correct temperature, the egg hatches in approximately 3 hours and 19 minutes.

The baby Kathreptis takes approximately 1 day and 13 hours to fully mature at default rates - slowly. 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.

Maturation has three phases: Baby (0–10%) lasts ~222 min and requires constant hand-feeding. Juvenile (10–50%) spans ~15h - it can eat from a Trough now. Adolescent (50–100%) takes ~19h - continues eating from troughs, nearly fully grown.

Imprint bonuses are significant: a fully imprinted Kathreptis gains 30% extra damage and damage resistance with its imprinter mounted. You'll be asked to cuddle, walk, or feed specific kibble at regular intervals during maturation.

Planning a mass raise? The Kathreptis raising calculator breaks down food needs per phase so nothing goes to waste. Expect ~222 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 Kathreptis babies at once - essential for batch breeding operations. Match your food choice to your play schedule - longer spoil timers mean less babysitting.

The Kathreptis, a tamable, aquatic, piscivore creature in ARK: Survival Ascended, is a common sight across multiple maps.

With 320 base Stamina, the Kathreptis has moderate endurance. Dealing 100% base Melee Damage, the Kathreptis brings respectable melee power to the table. The Kathreptis has 800 base Health - quite durable. It carries 250 base Weight - generous inventory space.

The Kathreptis is passively tamed - approach it carefully and feed it by hand without knocking it out.

Once tamed, the Kathreptis is a versatile aquatic mount for underwater exploration and resource gathering. It reproduces by laying eggs, which must be incubated between -75°C and 75°C. Defeating one in the wild grants 12 base XP. It can be cloned at a Cloning Chamber for 0.37 Element plus 0.01 Element per level.
