The four basic species of the ocean

The ocean is the largest world on earth
So?
What are the creatures in the ocean world?

Read a book today
The author thinks
The four basic species of the ocean are grass/snails/fish/worms.

Plants all belong to grass.
Conch is conch/shell/etc.
Fish wraps mammals, whales, etc.
Insects, the author refers to sea turtles as insects.

It seems that this author should be classified according to appearance.

After reading,
Guess everyone,
So which species is coral?

Corals are the bones of insects after death.
According to biology, it should be insects,
But the author regards it as grass.

So intuitively classified according to appearance,
sometimes,
For ordinary people,
On the contrary, it is easier to be accepted.

海洋的四大基础物种

海洋是地球最大的世界
那么?
海洋世界有哪些生物呢?

今天看了一本书
该作者认为
海洋的四大基础物种, 分别为草/螺/鱼/虫.

植物类通通归属于草.
螺就是海螺/贝壳/等等.
鱼类包过哺乳类的鲸鱼等等.
虫类,作者把海龟是为虫类.

看起来, 这个作者应当是根据外型来归类的.

看完之后,
大家猜猜,
那么珊瑚是算哪个种类呢?

珊瑚是一种虫类生物在死亡之后的骨头,
按照生物学, 应当是虫类,
但作者把它视为草类.

所以直观性的依照外型来分类,
有时候,
对普通人而言,
反而比较容易被接受.
