Kirsten Hecht, a PhD student at the University of Florida, started the hashtag #HERpers to highlight the work of women in herpetology – the study of reptiles and amphibians.
Since then plenty of other women in science have taken up the call, tweeting photos of themselves in the field.
Hecht told BuzzFeed News the hashtag came about when she was with female colleagues on her way to a herpetology meeting last weekend.
"We were joking around about being a female herpetology gang," said Hecht. "I kept thinking about how I know some really fantastic hard-working female herpetologists."
"With the popularity of #WomeninSTEM, it seemed like it would be a great time to highlight all the science and conservation work being done by women in our field."
"I also wanted to remind people that some of us love to get muddy and catch awesome critters."
All kinds of critters are being shared on the hashtag. So far there have been lots of snakes.
