Ross - as a follow-up to my stuff about top predators take a look at this: http://news.yahoo.com/s/ap/20070330/ap_on_sc/sharks_shellfish_5 We've just about eliminated sharks around here. Shark teeth, that I used to make into pendants for Spanish tourists, now cost six times what they used to about 5 years ago. I can't make a profit from them anymore, so I use 40My old fossil ones from NY state instead. The world is going to hell in a basket. regards Richard Parker Siargao Island, The Philippines. My website at www.coconutstudio.com is about the island and its people, coastal early humans, fishing, coconuts, bananas and whatever took my fancy at the time. ---------------------------------------------------------------------- [log in to unmask] - a forum for informal discussions on molluscs To leave this list, click on the following web link: http://listserv.uga.edu/cgi-bin/wa?SUBED1=conch-l&A=1 Type your email address and name in the appropriate box and click leave the list. ----------------------------------------------------------------------
