Vaquita

https://faunafocus.com/home/july-2017/#jp-carousel-1783

Unlike most other porpoise species which breed every year, vaquitas give birth every 2 years.

The maximum population growth rate of the vaquita is not likely to exceed 4% annually, a rate commonly used for porpoises.

Sexual maturation is estimated to occur at 3-6 years of age. Most births occur in early March, presumably following a peak in ovulations and conceptions in approximately mid-April. The gestation is estimated to be 11 months. The generation time for the vaquita is estimated as 10 years, therefore three generations is approximately 30 years.
