Scientists discover kadedekedewa, a species of ‘walking’ shark in Papua New Guinea

Scientists discovered a new 'walking' shark species, Hemiscyllium dudgeonae, in Papua New Guinea. These sharks use fins like legs to move across reefs and can survive out of water for hours. Researchers found the species after noticing a unique colour pattern. The shark, named after Christine Dudgeon, may already face threats due to its small range.
