Document Summary
Lecture 7 notes finding the way around. When you"re really small, you have a small reynold"s number: this poses different limitations that larger animals. Barnacles are limited by the viscosity of the fluid. For large animals, the limitation is inertial force (we are big animals and you need to move us) When you have a jaw, you also need to chase prey and do other things to capture the prey.
