1．What are they
Before you watch
Komodo dragon
(科莫多巨蜥)
Duck -billed platypus
(鸭嘴兽)
Nautilus
(鹦鹉螺)
Origin
Komodo dragons were first encountered by Western researchers in 1910 who said the ancestor of the Komodo dragon most likely evolved in Australia and spread westward, reaching the Indonesian island of Flores 900,000 years ago.
Size
The Komodo dragon is the largest lizard in the world. It can grow to three metres in length and can weigh about 135 kilograms. Despite its size and weight, it can run for short distances at up to 20 kilometres per hour.
Origin
The oldest discovered fossil of the modern platypus dates back to about 100,000 years ago.
Features
The duck-billed platypus is a small egg-laying mammal (up to 60 cm in length) found only in Eastern Australia including Tasmania. As its name suggests, it has a mouth that looks like a duck’s bill, while its thick fur and flat tail are similar to those of a beaver（海狸）.
Origin
Fossil records indicate that the nautilus has survived relatively unchanged for around 500 million years.
