Taxon-Specific Life Stage Machine

How Orca (Killer Whale) progresses through distinct morphological phases.

🐋
Stage 1

Calf

0–12 months

Born tail-first into water; nurses rich milk while learning matrilineal pods.

Anatomical Highlights:
  • •Blubber accumulation
  • •Open swimming at birth
Ecology: Dependent calf.
🐋
Stage 2

Juvenile

1–5 years

Weaning and hunting/foraging apprenticeship.

Anatomical Highlights:
  • •Rapid length growth
Ecology: Juvenile cetacean.
👑
Stage 3

Adult

Maturity onward

Prime adult using cooperative.

Anatomical Highlights:
  • •Adult size
  • •Reproductive maturity
Ecology: Adult cetacean.
🌟
Stage 4

Elder

Late life

May lead groups or show senescence depending on species.

Anatomical Highlights:
  • •Tooth wear in toothed whales
Ecology: Elder.
