I found the above photo on The Guardian as a SkyPixel aerial photography competition winner. The caption reads "A [lobster] farm in Tuy Hoa, Phu Yen province, central Vietnam."
The photo got me thinking about what defines a "lobster." I couldn't imagine any of the bottom-dwelling lobsters I once enjoyed at the West Street Cafe having come from such floating farms. As I researched "lobster farming" I found video like this intriguing one:
I thought "he calls them lobsters, I call them crayfish." But perhaps I'm provincial and too restrictive in my vocabulary, since prawns and scampi are classified as lobsters. Maybe it's the freshwater vs. seawater habitat that is the distinguishing characteristic. No time to pursue it further. Good photo and video. You learn something every day.
