Bottlenose Dolphin Biosonar Click Cards!: A handy teaching tool for those looking at the properties of dolphin echolocation. This PDF will print a sheet of business-card sized handouts showing the waveform of a dolphin click at the same scale as it would have propagating through sea water. The distance sound travels in 58 microseconds in sea water is the width of a business card, and a dolphin biosonar click fits nicely within that scale.
