Chapters 1, 2, and 3 can at last go online, and there are other features such as an online glossary with animated demonstrations, and a dolphin-based preview to compliment the bat one. Please dip in and take a look at Chapter 1 for some bats and their sonar chirps, and some dolphin sonar clicks. Look at chapter 2 to see the discovery of biosonar in the 18th Century and developments to the present day. Look at chapter 3 to gain more understanding into how biosonar works.

Keep your eyes peeled for further developments, including a directory of the interactive parts of the site, and printable versions of the interactive material.

Rather can checking back here repeatedly, you can get updates on further progress, and be the first to know when further components of this site go on-line. Please e-mail the webmaster, who will be pleased to add you to our mailing list.
