In 1986, for instance, studies of the megabat visual system turned up "about 30 very striking features which were thought to be unique to primates," says John D.
But when Speakman and Racey went on to compare the energy costs of flight in microbats and in larger, sighted bats of the suborder Megachiroptera, controlling for the difference in body size, they discovered that microbats and megabats use approximately the same amount of energy.
Echolocation's negligible energy cost during flight, combined with its superiority over vision as a means of detecting insects, raises the question of why so few megabats have sonar rather than visual systems, Speakman and Racey assert.
