Common Adaptation

Clownfish are known ‘Nemo’ by most of the kids because of the movie” Finding Nemo.” Though they look harmless, clownfish are known to be somewhat poisonous.

Clownfish can also camouflage with the same color as anemone, especially at night. This helped them to be less visible by other predators.


It is believed that clownfish are born as all males and that the dominant fish can be female.
