Amoebae survive in hypotonic environments because they have contractile vacuoles to pump excess water out of the cell. To regulate osmotic pressure most freshwater amoebae have a contractile vacuole (CV) that expels excess water from the cell.

The CV bursts and expels its water and the cycle repeats. I couldn’t find a good video on amoebae but here is a good video showing the operation of CVs in paramecia.
