Researchers have described a new-to-science species of walking shark, which lives in the remote, shallow waters off southeastern Papua New Guinea. The newly named Dudgeon’s walking shark (Hemiscyllium dudgeonae) is a type of epaulette shark, a group of small sharks famous for their ability to use their fins to “walk” when stranded in tidal shallows. Walking sharks are nocturnal, feed on invertebrates and aren’t dangerous to humans. Christine Dudgeon of the University of the Sunshine Coast in Australia and her colleagues were surveying the waters in and around Papua New Guinea’s Milne bay after midnight when she captured a meter-long fish by hand. Dudgeon told Mongabay by email that she initially thought she’d caught a Michael’s or Milne Bay walking shark (Hemiscyllium michaeli), also known as a leopard epaulette shark, “which was the one that we were looking for.” Back on the boat and under light, Jess Blakeway, a PhD student at the university and the study’s lead author, noticed the shark’s color pattern was different from any of the walking sharks she had worked with before, according to a press release. Although all walking sharks in the genus Hemiscyllium are similar in size and shape, species can be uniquely identified by their markings, Dudgeon told Mongabay. Dudgeon added the Milne Bay walking shark has very distinctive leopard spots while the species she collected had white stripes and small brown spots all over it “and didn’t look like any of the other species at all.” Over the next two days,…This article was originally published on Mongabay
