Lily Winter (top) and Lana Austin (back) match up during the “Atomic 6 – Atomic Fighter” wrestling show at the Azvex Brewery in Liverpool, Britain, 21 February 2024. Atomic Pro Wrestling was started in 2023 by wrestling enthusiasts and former training mates Matt Davies, Declan McCarthy (stage name Declan Sands) and Chris Welsh as a way to showcase emerging male and female wrestling talent from England’s North and North West regions, which they felt were being overlooked and under-represented. In contrast to the highly polished world of televised WWE (World Wrestling Entertainment), Atomic takes a DIY approach, holding shows at a local brewery large enough to make way for the ring, and where customers can enjoy craft beer as they watch the wrestling matches from up close.

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.
