I have a gorgeous photo of a group of Golden Stingrays on my calendar this month–somewhat similar to this.

National Geographic has this piece describing them.

A nice video here on them:

Ocean Conservancy has this up on the possible threat to rays.   There are some species that are endangered, according to this.   I guess the question is…does it make sense to keep pushing the envelope until a species is endangered, or is it better to pull back and not push it to the edge?  Why is it so hard for us to keep the balance?
