“保护色”英文怎么说

保护色 动物学中用 protective coloring

如:Animals' protective coloring enables them to blend with their surroundings.
动物的保护色使它们能和环境融成一体而不被发现。

实际翻译中可以直接用camouflage 我更支持这种翻译

例:
Some insects have a natural camouflage which hides them from the attack of their enemies.
有些昆虫有一种天然的保护色可以防止敌人的袭击。

The polar bear's white fur is a natural camouflage, ie because the bear is hard to see in the snow.
北极熊的白色毛皮是天然的保护色.

【名】protective coloring.
例句：动物的保护色使它们能和环境融成一体而不被发现.
Animal ' protective coloring enable them to blend with their surroundings.
