The Hector's Dolphin is an extremely endangered species for a number of contributing factors. One is pollution, because we leave our garbage around oceans this gets into the sea and dolphins eat it and can get sick or get stuck in it and drown. The Hector's Dolphin has a leisurely breeding habit and the female only begins breeding hen they are between 7 and 9 years of age and they then only give birth every 2 to 4 years. This slow rate of reproduction makes their population vulnerable to threats such as set nets or gill nets. Because the breathe air, when they are trapped in the nets they drown and a study shows that a third of their entire population has died this way. The Hector's Dolphin evolved without having any sea or land predators and since the arrival of humans, they have encountered many problems and are now nearly extinct due to them not being well adapted.
