Copepod up close

This image of a tiny crustacean called a copepod is one of the winners of this year's Nikon Small World photography competition. At Deep Sea News, blogger ParaSight explains how the photographer, scientist Jan Michels, got the shot:

That right there is one gorgeous copepod, one of the bigger and more important groups of planktonic crustaceans. It looks huge but is actually tiny; probably 1-2mm. You can see how much richer and more detailed the image is (although the colour is stained flouresence, not natural). That particular image uses a technique called confocal microscopy, which uses lasers and clever optics to achieve great depth of field (where everything is in focus).
