Hectors dolphin diet
There is a possibility that populations have declined to about a third to half of their size since 1970 because of gill net entanglement, with bycatch of this species occurring throughout its current range. These dolphins are part of the cetacean species which also include whales and porpoises. A current estimate puts the population at around 7000 individuals. A dolphin that plays with seaweed and blows bubbles. And so we are working to ensure such species can live and thrive in their natural habitats. In winter the distribution reaches further offshore, out to 15 nautical miles. Courtship is a fairly elaborate process, involving chasing and belly displays. Females reach maturity at around 7 to 9 years of age, and males between 6 and 9 years. They communicate using a combination of clicks and whistles and interact in a variety of ways including leaping out of the water, chasing each other, blowing bubbles and playing with seaweed.

Their diet is believed to be more influenced by how large their prey is rather than what type of prey it is.
Feeding is a group activity, and prey includes fish and squid. They are also a very curious species and are known to approach and swim near boats.

Usually, calves are born in late spring to early summer and the mother will not give birth again until the calf is fully independent. 9 ft. Currently the main threat to the survival of this species is bycatch in net fisheries, particularly entanglements in gillnets that have been reported to occur throughout the species range. The WWF is run at a local level by the following offices. 2 - 1. These dolphins often prefer to travel in small groups of up to 5, although they can be seen in pods of 20 or more during mating periods.
