Was having ramen with Bobo yesterday. As usual, we generated some questions from our intellectual discussion:

Q: Do fish drink water? (I googled this and the first result is a webpage titled Nature Questions from Kids. How humiliating.)

A: Freshwater fish do not actively drink water, but absorb the water through their skin and gills. On the other hand, saltwater fish do actively drink sea water. Their gills process the water and take out the salt.

How clever!

Q: How do foetuses breathe in the womb?

A: Foetus do not breathe in the womb. They get their oxygen and nutrients from the mother through the placenta. Babies only begin to breathe when they are born.

And by the way,
The foetus is able to smell the amniotic fluid for at least 3 months. After 6 months when taste buds develop, the foetus can taste the amniotic fluid in which it floats.

Eeuks.

This comes from a less humiliating source – the National Geographic Channel.
