"Disco Clam" Lights Up To Scare Predators Away
sciencehabit writes When predators get close, the bright, orange-lipped "disco clam" flashes them to scare them off. But it's not just the light that's important. Researchers have found that the clam has sulfur in its fleshy lips and tentacles and suspect that, like another clam species that drop tentacles laden with sulfuric acid to deter predators, the disco clam's sulfur also gets converted into a distasteful substance. The flashing may warn predators away, similar to the bright orange of a monarch butterfly warning birds of its toxic taste.
Back in the mid 90's I was working for a small company that had a marketing director who, when he saw something on the "world wide web" that he thought would be useful to us, would actually print it out and fax it to us.
And then later he hired someone to make up some images for the web site. He called me up and asked what was the best way to get it to me? Which courier service? I said "Can't you email them?" "Oh no," he said. "I want to make sure you get them."
