A newly identified species of walking shark, known as Dudgeon’s walking shark, has been discovered in the shallow coastal waters off southeastern Papua New Guinea. This fascinating shark uses its fins to walk across tidal reefs, adding to the unique behavior known among epaulette sharks.
- Dudgeon’s walking shark uses fins to ‘walk’ in tidal shallows.
- Species discovered in remote Papua New Guinea waters.
- First new walking shark species identified since 2013.
What happened
Marine researchers surveying the remote shallow waters off Papua New Guinea’s Milne Bay found and described a new species of walking shark, named Dudgeon’s walking shark (Hemiscyllium dudgeonae). The discovery came after capturing an unusual shark by hand during a nocturnal dive and noticing its unique color pattern, which differed significantly from known walking sharks in the region. Subsequent encounters confirmed the presence of multiple individuals of this species across several reef sites.
Identification was solidified through genetic analysis, distinguishing this shark from its relatives such as the Milne Bay walking shark. This species moves on its fins across coastal reefs, feeding on invertebrates during nighttime hours. With this discovery, the count of recognized walking shark species has risen to ten, marking the first new species described in this genus since 2013.
Why it feels good
Discovering a new species highlights the richness of life in even well-explored shallow marine environments, reminding us how much remains to be learned about Earth’s oceans. The finding celebrates the persistence and curiosity of scientists and local communities dedicated to protecting and studying Papua New Guinea’s vibrant coral reef ecosystems.
The new shark species also honors Christine Dudgeon, whose contributions were vital to the discovery, manifesting how individual passion and teamwork can lead to exciting scientific breakthroughs. It sparks hope for further marine conservation efforts and inspires ongoing exploration and respect for ocean biodiversity.
What to enjoy or watch next
For those interested in nature documentaries and marine biology, watching programs featuring epaulette sharks and walking sharks offers a glimpse into their unusual locomotive abilities and intriguing behaviors. These sharks’ ability to 'walk' using their fins in tidal pools showcases evolutionary adaptation worth exploring through visual storytelling and scientific outreach.
Locally, conservation groups and researchers hope to raise awareness about this new shark’s habitat, which may be vulnerable due to its limited range. Supporting marine protection initiatives in Papua New Guinea and following news on biodiversity discoveries can help contribute to preserving these unique species and their environments for generations to come.
