Like everyone, I sometimes have days on which I do little but watch octopus videos:
This species, the Indonesian mimic octopus, was just discovered twelve years ago. It is fabulous.
It's known to mimic at least 13 different animals or corals, some of them deadly poisonous, though scientists admit they don't always know what they're seeing.
They're lost due to habitat degradation, fishing bycatch, recently even the pet industry.
It saddens and sometimes horrifies me that we can be doing such damage to species that weren't identified by scientists until our current crop of high school students was first learning to read.
I don't eat octopus, and I do what I can to help protect its habitat and the creatures in it. Biodiversity is essential, no species is completely expendable, but octopuses are just too damned cool to lose.
I collect natural history, environmental, and geography books, almost compulsively. I look for used versions where I can (to save paper) but also appreciate that many of these books come out in runs of a few thousand copies, and aren't profit-makers for the publishing companies, so when they come out new, I buy them while they're new. If you like Geographile and want to let me know, please either comment on my posts, or visit my Powell's wishlist to feed my book collection. You might find books you like there, too.
