Picture Of My Fish A hector’s dolphin are mammals they need air to breathe and their young suckle for milk dolphins are not porpoises .
English Name The Hector’s dolphin was named after Sir James Hector. Sir James was the curator of the colonial museum in Wellington (now the museum of New Zealand - Te Papa). He examined the first specimen found of the dolphin. Sir James lived from 1834 to 1907. He was the most influential New Zealand scientist of his time. This means that he was really onto it when it came to science and was really into learning about nature .
Maori Name The hector’s dolphin has several Maori names, such as upokohue and tukuperu,sadly none of these names are widely used now.Tutunairekurrai is the most common of the names for hector’s dolphin. It means special ocean dwellers some Maori people believed that the spirits of the dead would become Tutunairakurai.Tupoupou means to rise up vertically.perhaps this name arose from the dolphin’s habit of spyhopping

Extra! HOW YOU CAN TELL HOW OLD A DOLPHIN IS; When a dolphin is born it has teeth and each 1 year it grows older.Then it grows a layer of this stuff you call hollow cones, and if you cut a tooth off a dolphin you can see how old that dolphin is by counting the hollow cones but this hollow cone can also be called annual rings just like the one’s on trees.Each time when it grows a layer one will be dark and next year 1 will be light. If you see a dolphin with white scars on their skin that means that,that dolphin has been attacked by a shark!And if it has dark grey ones it means that that dolphin has skin disease.
KEEPING WARM (EXTRA ) Water conducts heat more effectively than air.In baths at 20 celsius you would eventually die from exposure.Marine mammals maintain a high body temperature of 36-37 celsius.So insulation is a real problem.Seals solve the problem with two layers of fantastic fur,the inner layer so dense than the skin never gets wet.Dolphins and whales use blubber , a dense oily fat layer just under the skin,2-3 centimetres thick in hector dolphins and up to 50 centimetres thick in some whales.
Lifespan Hector’s dolphins mature at about 8 years and they live around to 15-18 years to they die.
