What is the typical gestation period length for a female walrus carrying a single calf?
Answer
Around 15 months
The reproductive cycle of the walrus is relatively protracted compared to many other marine mammals. The gestation period, the time a female carries her developing young, is quite long, extending for approximately 15 months. Following this extensive period, the female gives birth to a single calf. This slow reproductive pace is further emphasized by the long dependency period; nursing often continues for a year or more, meaning a female typically births only once every two to three years. This slow rate implies a significant vulnerability for population recovery following substantial losses.
