143. bats and toothed whales had many opportunities to evolve echolocation techniques that differ from each other, since their nearest common ancestor was incapable of echolocation. nevertheless - as scientists have known for years - bats and toothed whales rely on the same range of ultrasonic frequencies, between 15 to 200 kilohertz, to hunt their prey. this overlap in frequencies is surprising because sound travels about five times faster in water than in air, giving toothed whales an order of magnitude more time than bats to make a choice about whether to intercept a potential meal. bats increase the number of calls per second (what researchers call a "buzz rate") while in pursuit of prey. whales were thought to maintain a steady rate of calls or clicks no matter how far they were from a target. but newresearch shows that wild whales also increase their rate of calls or clicks during a kill - and that whales' buzz rates are nearlyidentical to that of bats, at about 500 calls or clicks per second. (science daily) a. before developing the ability to increase their buzz rate while pursuing prey, toothed whales emitted a steady rate of calls. b. five hundred is the maximum number of calls that both bats and toothed whales can process per second. c. bats typically use an ultrasonic frequency range of 150 to 200 kilohertz to hunt while toothed whales use a range of 15 to 200. d. bats and toothed whales developed similar echolocation techniques despite their different environments.
