Archerfish: super spitters!

Archerfish catch insects by squirting a powerful jet of water at them. To be successful, they must learn how to deal with several fundamental laws of physics, so that they can master projectile motion (see chapter 3) and the consequences of refraction of light at the water surface (refraction is covered in PHYS 1030). To read more about how they do this (and see some nice pictures), click on the following links:
