title: Meet the Shark That Prefers Walking to Swimming: The Discovery of Hemiscyllium dugeonae
description: While we often picture sharks as apex predators, a newly discovered species in Papua New Guinea challenges this notion by literally "walking" across the seabed on its fins. This unique shark, Hemiscyllium dugeonae, uses its fins like limbs and even boasts a "decoy eye" to fool predators, showcasing an unhurried and localized lifestyle far removed from the typical high-speed chase.

# Meet the Shark That Prefers Walking to Swimming: The Discovery of Hemiscyllium dugeonae

When we picture sharks, we typically envision the apex athleticism of a Great White, a torpedo of muscle capable of hitting 25 miles per hour. But in the shallow tide pools and vibrant reefs of Papua New Guinea, evolution has taken a far more leisurely turn. Here, a newly discovered species has traded the high-speed chase for a stroll, literally "walking" across the seabed on its fins.

  

## Evolution Discards the "Swim" for a "Stroll"

The *Hemiscyllium* genus is defined by a group of reef dwellers that have mastered a curious, unhurried gait. Instead of pulsing through the water column, these sharks use their pectoral and pelvic fins like primitive limbs to paddle and "crutch" their way across the jagged seafloor. They are diminutive and accessible curiosities, generally maturing at a modest 70 to 80 centimeters. While one outlier was recorded at 107 centimeters, most remain small enough to navigate the cramped crevices of their coral homes.

## The Shark with a "Third Eye"

The newly identified *Hemiscyllium dugeonae* is a master of visual deception, sporting a complex tapestry of brown spots, white dots, and stripes. Its most arresting feature is a massive, dark spot situated just behind the head that functions as a "decoy eye." This biological mimicry serves as a clever defense mechanism, intended to confuse predators into mistaking the shark’s shoulder for its head. For the scientists on the ground, the discovery was as personal as it was professional.

"The discovery of sharks does not happen often," notes Dr. Christine Dudgeon, for whom the species is named. "And this is the first time a species has been named in my honor."

  

## The Ultimate Ocean "Homebodies"

While many sharks are global nomads, these walking species are the ultimate homebodies of the marine world. Some individuals spend their entire lives within a territory as small as a few hundred square meters, rarely venturing into deeper water. This extreme sedentary lifestyle is largely a result of their reproductive biology; they are oviparous (egg-laying) creatures. Without mobile larvae or the urge to migrate, they remain tethered to the specific patches of reef where they were born.

  

## Shattering Previous Scientific Assumptions

Expeditions conducted between 2023 and 2025 in the Milne Bay province have delivered a major blow to old biological certainties. Scientists long assumed that distinct species required physical barriers, such as deep-sea rifts or massive river outflows, to evolve in isolation. However, in Eastern Papua New Guinea, researchers found that these "walking" territories actually overlap. These sharks remain genetically and behaviorally distinct despite sharing the same water, suggesting a much more sophisticated process of speciation than previously imagined.

## A Race Against Extinction

Despite just entering the scientific record, *Hemiscyllium dugeonae* is already part of a genus under immense pressure. Of the ten known species of walking sharks, 50% are already listed on the IUCN Red List as threatened with extinction. This makes the upcoming expedition in October a critical mission for the team. They intend to gather more granular data to determine exactly how vulnerable the *Dugeonae* species is and what protections are needed to ensure its survival.

  

## A New Perspective on Marine Diversity

The discovery of *Hemiscyllium dugeonae* reminds us that the most profound biological secrets are often hidden in plain sight along our coastlines. It challenges our narrow definitions of what a "shark" should be and highlights the incredible specialized niches life can occupy. As we continue to explore the shallow fringes of our oceans, we have to wonder: how much of the "known" world still remains a mystery, specifically regarding the fragile, walking wonders of our coastlines?
