predictable browsing

while rendering, compressing, exporting, uploading, and archiving, i frequently find myself with a limited supply of computer resources. so i defect to the world wide web for some text-based entertainment. this evening i happened upon an interesting series of articles on national geographic and my boredom immediately subsided.
i was intrigued by the study about arthropod spiracles and the link between respiration, atmospheric oxygen and insect size.
i was astounded by the incredible bite force of ancient crocodiles, and the even more impressive force between a dunkleosteus' quadruple-hinged blade-like jaws.
but i was slightly disturbed by one quote by a californian biologist.

"A great white is about the size of the clasper, or penis, of a male megalodon"

says Peter Klimley a shark expert and neighborhood sex freak at the University of California at Davis. Normally when one wants a good size comparison, genitals are the last thing on my mind.
Although the reverse is fine. Did you know a blue whale's penis is the size of a mid-sized sedan?
Why do i know that?
