Wednesday March 8 marks International Women's Day, with festivals, concerts and exhibitions among the numerous events planned around the world to celebrate the achievements of women in society. The annual event has been held since the early 1900s and traditionally promotes a different theme each year, with this year's edition calling on people to #BeBoldForChange and push for a more gender-inclusive working world. Reuters photographers have been speaking with women in a range of professions around the world about their experiences of gender inequality.

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 reveller wearing a bearskin costume poses during the Bearskin Parade in Comanesti, Romania, on December 30, 2022. More than two hundred “bears” and dozens of musicians, surrounded by police and tourists, took part in the end-of-the-year parade. Young men and women dressed in real bearskin and traditional costumes paraded to chase away the evil spirits of the coming year. In all regions of Romania similar events exist but it is in this historical region of Moldova that they are the most developed. Comanesti has become the centre, attracting more and more troupes of dancers every year. (Photo by Daniel Mihailescu/AFP Photo)
