> Landings this catastrophic [...] Size also throttles the consequences of impact - the mice bounce, humans break, horses splash pattern. Other fun is the short jump distance-compared-with-body-length - inertial mass vs drag goes as L^3 vs L^2. And short legs encourage high takeoff accelerations - flea jumps are bottlenecked on 100+ G tolerance. Mating calls can also be size-bottlenecked in creation. Smaller crocodilians used to exist, but extinctions left only those with long-range infrasound calls. Which you have to be long to make. So adult males have been trapped large. Perhaps they too will someday escape.
