[iframe id="https://www.facebook.com/plugins/video.php?href=https%3A%2F%2Fwww.facebook.com%2Fnoman.almoktadir%2Fvideos%2F1072471419536791%2F&show_text=0&width=560"] A rare sight of two snakes performing a ritual dance caught on video at Jahangirnagar University in Savar has resurfaced on social media. The video was captured originally by Noman Al Muktadir, a Masters (batch 41) student of zoology at JU from a lake in the campus. It has been reposted by many others since. After the video began going viral on the web, Noman posted it on Facebook on Saturday. Monirul Islam, a professor of zoology at the university, identified the snakes as Oriental or Indian Rat Snakes, locally known as Daraj or Darash. Male Darash snakes perform this ritual combat dance as a test of strength and to establish their dominance in the territory. The ritual can go on for over an hour, at the end of which the dominant male mates with the female. "This is not a rare incident. The snakes perform this ritual in every mating season, which begins in early monsoon," Monirul said. "But it is certainly a rare sighting here," he added. Darash snakes are non-venomous and are found all over the Subcontinent. JU Zoology student Noman Al Moktadir, who filmed the Darash dance.

"The problem is that many of those posting the video are calling this 'snake romance,' 'snake mating' or 'venomous snakes,'" he wrote. "In fact these are two male snakes fighting. Also, Darash are not venomous snakes. "Whether you upload the video or call it your own, don't give people false information," Noman said.
