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.

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.
