With its huge eyes, comical name and diminutive size, Mark R. Smith’s image of a baby Hawaiian bobtail squid can’t help but raise a smile. A curiously endearing creature, the cephalopod is just 1.5cm across, its mantle cavity bearing more than a passing resemblance to a rather natty shower cap. But it is also a beautiful example of symbiosis – nature’s version of “I’ll scratch your back if you scratch mine” – for on the underside of the squid is a light organ which houses bioluminescent bacteria. The squid offers the bacteria protection and food, while the bacteria emit a glow – a handy trait that the squid uses to offset its silhouette, helping it to evade predators in the depths below. Mark R. Smith’s entry combines several images of a Hawaiian bobtail squid with different focus lengths to create a final picture with greater depth of field than normal. (Photo by Mark R.

“G.I. Joe is a line of action figures produced by the toy company Hasbro. The term G.I. stands, in popular usage, for Government Issued and after the First World War became a generic term for U.S. soldiers. The origin of the term dates to World War I, when much of the equipment issued to U.S. soldiers was stamped “G.I.”, meaning that it was made from galvanized iron. The development of G.I. Joe led to the coining of the term “action figure”. G.I. Joe's appeal to children has made it an American icon among toys”. – Wikipedia. Photo: Vintage G.I. Joe figurers are on display at the 2003 Hasbro International G.I. Joe Collectors' Convention June 27, 2003 in Burlingame, California. (Photo by Justin Sullivan/Getty Images)
