Different animals have different kinds of colour vision. Some have very poor colour vision while others have quite good colour vision.
In fact, some birds and bees have super colour vision and see colours that $\underline{1}$ don’t see.

That “fever-heat” is what $\underline{6}$ a pit viper a different of vision. Owls and other night-time animals can see at night when it is too dark for us. Scientists recently found that the gecko (壁虎) can tell blue from grey $\underline{7}$ in a very dark situation!
Scientists say that good colour vision helps animals find $\underline{8}$ on the land or in the water. For land animals, good colour vision helps tell the $\underline{9}$ between ripe (成熟的) red fruit and unripe green fruit.
