With human coastal populations and infrastructure growing at an exponential rate, an increased global demand for fisheries products, and a rapidly expanding maritime transport industry, threats of entanglement in fishing gear, ship strikes, and habitat loss have never been more severe. They have distinct black facial markings, short stocky bodies and a dorsal fin shaped like a Mickey Mouse ear. They are classified as "nationally vulnerable". There is also a sub-species called Maui’s dolphin living off the west coast of North Island which is the rarest and smallest known sub-species of dolphin in the world. The Hector’s dolphin and the Maui’s dolphin are found only off the coast of New Zealand. There is a 68% probability that the population is continuing to decline. Hector’s Dolphin has a sub species called ‘Maui’s Dolphin’ (Cephalorhynchus hectori maui) which is found off the northwest coast of New Zealand’s North Island, both dolphins are endemic to […] The total population today is estimated to be around 7,400 animals. Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species. Hector’s Dolphin is also known as the White-headed Dolphin (Cephalorhynchus hectori). In the 1970s their population sat at around 29,000. Hector's dolphin (Cephalorhynchus hectori) is the best-known of the four dolphins in the genus Cephalorhynchus and, along with its subspecies Maui's dolphin, is the only cetacean endemic to New Zealand.At approximately 1.4 m (4.6 ft) in length, it is one of the smallest cetaceans.. 1988 Helen Clark (then NZ's Minister of Conservation) creates New Zealand’s first marine mammal sanctuary, to offer some protection to Hector’s dolphins around Banks Peninsula. Hector’s Dolphin is also known as the White-headed Dolphin (Cephalorhynchus hectori). Maui’s dolphins (Cephalorhynchus hectori maui) are the smallest and rarest marine dolphins on earth and inhabit coastal waters up to a water depth of 100 metres.
Population structure and dispersal rates were assessed using 281 samples collected from individual Hector’s dolphins of ten population groups representing the known geographic range of this species. 1993). Living in coastal areas, the animal suffers from a number of factors, including pollution, vessel traffic as well as modification of its natural range. Hector’s dolphins are the smallest and rarest marine dolphins in the world. Mortality of Hector's dolphin (Cephalorhynchus hectori) in gill‐net fisheries is a threat to local populations throughout its range.
Established in 1964, the IUCN Red List of Threatened Species has evolved to become the world’s most comprehensive information source on the global conservation status of animal, fungi and plant species.
Hector’s Dolphin has a sub species called ‘Maui’s Dolphin’ (Cephalorhynchus hectori maui) which is found off the northwest coast of New Zealand’s North Island, both dolphins are endemic to […] Population viability analysis (PVA) is commonly used to estimate the probability that a population will decline or become extinct under specified conditions within a certain amount of time (Soulé 1987; Shaffer 1990; Boyce 1992; Burgman et al. Estimated population size and decline of Maui’s dolphins . It is a tough time to be a whale or dolphin.
