Today, Hector’s dolphins (Cephalorhynchus hectori hectori) are listed on the World Conservation Union’s (IUCN) Red List as ‘endangered’, and are among the most rare of the world’s 32 marine dolphin species.
Fewer and fewer
5 peer-reviewed scientific research papers about Hector’s and Maui’s conclude numbers are decreasing.
Scientists agree that Hector’s dolphin numbers were between 21,000 and 29,000 in the early 1970s, compared with an estimated 7000 today.
The internationally recognised IUCN has peer-reviewed the population information and uses this as the basis for classifying Hector’s as ‘endangered’.
