Life in space is a challenge for humans because you can't breathe like you do in earth as in space, you always eat dried food, and people who move in their sleep have to deal with being strapped to their bed.
To do this you need an increase in pressure and oxygen

She has no challenge.

Humans have not been able to find out when sharks nest. Did you know humans know more about outer space than sea life?
