Extinct and Endangered animals



Tuatara
Tuatara is reptile. They have been said to be living fossils. They have remained mostly unchanged since the age of dinosaur. It was about 220 million years ago. They has been endangered animal since 1895. That baby are born as whether male or female depends on the climate. If the temperature of ground is over 21℃, more males tend to be born. These days, the temperature of ground has become warmer because of global warming and more males have been born. There are sanctuaries where 1.7 times males inhabit.



Moa can not fly. They have no wings. Instead, they can run very fast.
As you can see the picture, Moa look like ostrich and emu.
They are huge!! They are normally 3.6m(12ft) in height and 250 kg in weight.
Maori had hunted Moa. Moa had gradually lost their numbers. they finally had gone extinct by 1500s.

I like science and unchanged animals but endangering was caused by human. It doesn't allow. I want to stop grobal warming and save all animals.
