habitat

Hector’s dolphins live in New Zealand.

Characteristics

The Happari dolphin is a dolphin that belongs to the genus Dolphin in the family Dolphin family. With a total length of 140 cm, it is the smallest of the cetaceans. Males are slightly larger than females. Adults are about 150cm long and weigh about 60kg. The head is gray with some black parts. It has a black line across the top of its head and also has black linings around its eyes. It has a rounded dorsal fin and a dark gray to black area around the spout. They have 24 to 31 teeth on each of the upper and lower jaws. Hector’s dolphins move in groups of 2 to 8 individuals. There are subspecies of the Hector’s dolphin. A subspecies lives in the northeast and is also called the “Maui dolphin”.

ecology

Hector’s dolphins are carnivorous and live on fish, squid, octopus, and krill. Life expectancy is about 20 years. Females continue to give birth every 2 to 3 years, giving birth to 4 to 7 offspring in one female’s lifetime. Birth takes place from spring to summer. The mortality rate in the first six months of a child is about 36%. This is because there is predation by foreign enemies.

endangered species

Hector’s dolphins have natural enemies such as killer whales and sharks, and children are often targeted. Humans are also a big threat to dolphins. Since 1970, the population is said to have halved due to gillnets. A sanctuary was established in New Zealand to prohibit gillnet fishing, halting population decline, but the Maui dolphin, a subspecies, is on the brink of extinction. The IUCN has classified the Maui dolphin as critically endangered, and the Marine Mammal Society has issued similar recommendations. In addition, it is designated as an endangered species even when viewed as a whole. New Zealand has begun testing a system to wirelessly tag and track the Hector’s dolphins with satellites, beginning ecological studies to help protect the dolphins.

Breeding

Hector’s dolphins are endangered and impossible for the general public to obtain. See them at an aquarium or travel to New Zealand.
