Introducing Hector's & Maui's Dolphins
Hector’s dolphins and their close relative the Maui’s dolphin live only in New Zealand and are both the smallest and rarest marine dolphins on earth. Entanglement in gill and trawl nets has devastated them to near extinction. Unless things change, Hector’s and Maui’s dolphins will become extinct.

Slow Reproduction - Slow Recovery
Females don’t breed until they are 7-9 years old and only give birth to a single calf every 2-4 years.
With a life span of up to 20 years, mothers can only raise a small number of calves.
Maximum population growth for this species is a mere 2%. This means that a population of 100 can increase by just two individuals a year.
