When Emma and I were feeding Koi Carp in a hotel in Cebu, she came out with a very strange question

Hon, she said grinning, to which i replied yes dear, observing her adorable big grin. Do fish perspire???
To this, I was literally rolling around laughing

Now, Emma is in my opinion an extremely intelligent inquisitive girl, and I said I would ask around on the forum to gain a few laughs, opposed to googling it.

So there we have the question?
