8 Echolocation occurs only in the. – Sound is produced in the. – Sound is emitted through the. – Echolocation is used for catching prey and flying. http://content.lib.utah.edu/cdm4/item_viewer.p hp?CISOROOT=/wss&CISOPTR=1001 http://content.lib.utah.edu/cdm4/item_viewer.p hp?CISOROOT=/wss&CISOPTR=1001

9 So how can the bat be removed?????

10 How echolocation works: Animals calls, then to the echoes that return from various objects. They use these echoes to and the objects.

11 Echolocation http://videos.howstuffworks.com/animals/bat s-videos.htm http://videos.howstuffworks.com/animals/bat s-videos.htm Why can we hear some of the bat sounds and not others?___________________________. bats such as the ___________ we can not hear. _____________: Humans hear sounds ranging up to 20 kHz, while most bats use a broader range (from about 9 kHz to 200+ kHz)

12 Echolocation Why we can we hear some of the bat sounds and not others. Video explanation. Whispering bats such as the vampire bat we can not hear Humans hear sounds ranging up to 20 kHz, while most bats use a broader range (from about 9 kHz to 200+ kHz) http://videos.howstuffworks.com/animals/bats- videos.htm http://videos.howstuffworks.com/animals/bats- videos.htm

13 Echolocation Used primarily by and piscivores bats why?__________________________________ – Molossids – Noctilionids – Vespertilionids Some bats emit the pulses through the. – Rhinolophids. Why use high frequency sounds? – High frequency in air. Microchiroptera

14 Bat Diversity Earliest bat fossils are from the early Eocene of North America: – Icaronycteris index There are no intermediate forms - earliest bats are good bats. Why?_______________________ Mosquito 100 mya Bat Fossil 50 mya
