Australian researchers have discovered a new species of "walking" shark that can move across exposed reefs using its fins [1].
The discovery highlights the biological diversity of the region and the urgent need for conservation efforts as the species faces immediate environmental threats.
Found in the shallow waters off Papua New Guinea [1], the shark is capable of navigating reef environments by using its fins to propel itself. This specialized movement allows the animal to traverse areas that would be inaccessible to most other shark species.
Researchers said that the species is currently threatened by habitat degradation, fishing pressure, and climate change [1]. Due to these risks, a follow-up expedition is planned to assess the population and determine the extent of its range.
"New shark species don't come along that often, and it's most definitely the first one named after me," said the lead researcher [2].
The find comes amid a broader global effort to map marine life. Scientists involved in the Ocean Census mission said that 90% of ocean life remains undiscovered [3]. Recent surveys have yielded significant results, with some reports indicating more than 1,000 new ocean species have been discovered [4], while other data points to more than 800 new marine species documented as part of the global Ocean Census mission [5].
Unlike other recent finds, such as a "ghost shark" discovered off the coast of Australia [4], this walking shark is specific to the waters of Papua New Guinea [1]. The researchers intend to use the upcoming expedition to establish baseline data for the species' survival.
“"New shark species don't come along that often, and it's most definitely the first one named after me."”
The discovery of a specialized species in a limited range emphasizes how niche evolutionary adaptations make certain animals more vulnerable to localized environmental shifts. Because the walking shark relies on specific reef conditions, habitat degradation and rising sea temperatures could lead to rapid population decline before the species is fully understood by science.
