Taxon-Specific Life Stage Machine
How Blue Whale progresses through distinct morphological phases.
Calf
Born tail-first into water; nurses rich milk while learning baleen.
- •Blubber accumulation
- •Open swimming at birth
Juvenile
Weaning and hunting/foraging apprenticeship.
- •Rapid length growth
Adult
Prime adult using baleen.
- •Adult size
- •Reproductive maturity
Elder
May lead groups or show senescence depending on species.
- •Tooth wear in toothed whales
