Hector's dolphin - Ecology & Habitat
A dolphin that plays with seaweed and blows bubbles
The species is found in inshore waters, including river mouths, estuaries and shallow bays, commonly within about 5 nautical miles of the shore. In winter the distribution reaches further offshore, out to 15 nautical miles.
Social StructureThis dolphin tends to occur in groups of up to five individuals, which may aggregate temporarily. Young are reported to play with seaweed, blow bubbles and are involved with other 'games' which are considered to be important social behaviours. Hector's dolphin emits sounds that are thought to be used for communication, notably the complex clicks produced in large groups.
Life Cycle
Females reach maturity at around 7 to 9 years of age, and males between 6 and 9 years.
Breeding
Courtship is a fairly elaborate process, involving chasing and belly displays. Usually, calves are born in late spring to early summer and the mother will not give birth again until the calf is fully independent.
Diet
Feeding is a group activity, and prey includes fish and squid.
