Basilosaurus
Basilosaurus Egg & Breeding Calculator
The Basilosaurus gives live birth after mating, skipping the egg-incubation step entirely. Gestation takes approximately 8 hours at default rates.
Full maturation from baby to adult takes ~4 days and 19 hours (1x rate), progressing over an extremely long period, one of the longest in the game. Hand-feeding is required until 10% maturation. After that, a Feeding Trough handles the rest.
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.
The Basilosaurus's growth progresses through three stages: Baby (0–10%) lasts ~694 min and requires constant hand-feeding. Juvenile (10–50%) spans ~46h - it can eat from a Trough now. Adolescent (50–100%) takes ~58h - continues eating from troughs, nearly fully grown.
Imprint bonuses are significant: a fully imprinted Basilosaurus gains 30% extra damage and damage resistance with its imprinter mounted. Imprint requests include cuddling, walks, and specific kibble - check the wiki for which kibble to stockpile.

The raising calculator above shows exactly how much food you need for each maturation phase of the Basilosaurus. Budget ~694 minutes for the Baby phase - this is when hand-feeding or Maewing nursing is mandatory.
Raising multiple Basilosaurus simultaneously? Set the dino count and the calculator scales food requirements automatically. 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.
Found throughout the ARKs, the Basilosaurus is a tamable, aquatic, carnivore creature in ARK: Survival Ascended. Classified under the Soaker group.
At 2,400 base HP, the Basilosaurus is a proper tank. Dealing 100% base Melee Damage, the Basilosaurus brings decent hitting power to the table. Stamina sits at 300 base, providing average stamina. Weight capacity starts at 700, giving it excellent carrying capacity.
The Basilosaurus is passively tamed - approach it carefully and feed it by hand without knocking it out. Its preferred food is Exceptional Kibble.
Once tamed, the Basilosaurus provides safe and efficient underwater traversal with good utility. Breeding is via live birth rather than eggs, simplifying the process. Defeating one in the wild grants 15 base XP. It can be cloned at a Cloning Chamber for 0.75 Element plus 0.01 Element per level.
