Oh, I love this. A new species of sea anemone was discovered recently that parks itself on top of a hermit crab shell like a hat. It seems to feed partly off the crab's faeces, but it also excretes a hard shell that extends the crab's home. In return, it's carried around the seafloor like a king.

Tom Bowman has held his Pentagon press pass for 28 years. He says the Pentagon's new media policy makes it impossible to be a journalist, which means finding out what's really going on behind the scenes and not accepting wholesale what any government or administration says. n.pr/4q87Jwb
