Can fish cry? |
Water Animals
I don't know if fish get sad - it is very hard to know what an animal is feeling because we can't ask them like we can each other. Also, fishes don't have the face muscles that we do and can't make all the expressions that humans do (such as frowning and smiling).
However, they certainly don't cry. Fish lack the special duct which produces tears. Most land-living animals need tears to stop their eyes from drying out - as far as we know only humans cry when they are sad. Fishes don't have this problem as their eyes are permanently wet. Fish also get by without eyelids or eyelashes!
