First and foremost I have to thank Curtis for putting up with my long hours spent observing and photographing the elephant seals followed by the processing of the information on the computer.
Then there's also, my son, Chris who has constantly kept encouraging me to keep at it.
Besides these two, I have also been extremely fortunate to have had help from many researchers and scientists from around the world. Thanks to these very kind people who took time out of their busy schedules, I have been able to elicit numerous answers via email that I was unable to find for myself.
