The gestation period for a dolphin varies depending on the species, but generally ranges from 9 to 17 months. The specific length of gestation can depend on factors such as the size of the mother and the quality of her diet during pregnancy.
For example, bottlenose dolphins have a gestation period of around 12 months, while killer whales have a gestation period of 15 to 18 months. Some smaller species of dolphins, such as the spinner dolphin, have shorter gestation periods of around 9 months.
During gestation, the developing fetus is nourished by the mother through a placenta. When it is time to give birth, the female dolphin will move into shallow water away from the rest of the pod. She will then give birth to a single calf, which she will nurse and protect for several months before it becomes independent.
Overall, the length of the gestation period reflects the complex adaptations that allow dolphins to reproduce and thrive in their ocean habitats.
