1. Gestation:
* Dolphin pregnancies typically last around 12 months.
* The developing calf grows inside the mother's womb.
2. Birth:
* Dolphin calves are born tail-first into the water.
* Mothers usually give birth in shallow water, where their calf is less vulnerable to predators.
3. Newborn:
* Calves are born very dependent on their mothers for milk, warmth, and protection.
* They are able to swim and breathe on their own soon after birth.
4. Weaning:
* Calves begin to eat solid food around six months old, but continue to nurse for up to two years.
* They gradually become more independent from their mothers as they age.
5. Juvenile:
* Dolphins reach sexual maturity between 5 and 15 years old, depending on the species.
* They continue to learn and develop their social skills during this time.
6. Adulthood:
* Adult dolphins typically live for 20-30 years.
* They are responsible for raising their own calves, teaching them essential skills for survival.
7. Old Age:
* Older dolphins may become slower and less agile, but they often remain valuable members of their social group.
* They may even act as mentors to younger dolphins, passing on their knowledge and experience.
Key points to remember:
* Dolphins are mammals, not fish. They give birth to live young and nurse them with milk.
* The lifespan of a dolphin can vary depending on the species and environmental factors.
* Social interactions and learning are crucial throughout a dolphin's life.
It's important to note that these stages are not always clearly defined and there can be individual variations.
