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.

A student of the Sri Lankan ancient martial art “Angampora” performs during a practice session at the angam maduwa or fighting field, in Korathota, a suburb of Colombo, Sri Lanka, 07 September 2022. Sri Lanka's ancient martial art, Angampora, is thought to be thousands of years old. Anga translates to “body parts” and Angampora is a fighting art that uses body parts. Martial arts practitioners in Angampora were mostly in the king's service, and they were tasked with protecting the king and his kingdom. Angampora was practiced in secret for most centuries because the British, who colonized Sri Lanka, banned it in 1818 after seeing it as a threat. (Photo by Chamila Karunarathne/EPA/EFE)

An original 1850 puntabout rugby football is displayed at Rugby School in central England, March 18, 2015. Rugby School is known as the spiritual home of rugby. According to a popular version of the game's origins, it was on the school's playing field that in 1823, in a game that could loosely be described as football but was more like a brawl, a pupil called William Webb Ellis caught the ball and, instead of kicking towards the goal, sprinted with it – breaking the code and laying the way for modern-day rugby.
