I got into a discussion with a friend and we were uncertain if Mantis Shrimp had compound eyes or not. I typed a simple query into my preferred search engine and was referred to National Geographic's web page which would not let me read the article until I provided an email address and signed-up for... whatever.
Now, I get it. They are providing a service and providing an email address is hardly a burden. I'm just sick of feeling that I can't sneeze, at a time where internet security experts are reminding us to be more discriminate while online, with having to provide anybody and everybody that asks with all the details.

Incidentally, Mantis Shrimp have compound eyes.
