Deep-Sea Discoveries: Almond-Sized Crab and Minuscule Lantern Shark Unveiled in Marine Exploration

October 21, 2025 – 8:00 AM

Perth, Australia – A recent research expedition has unveiled two previously unknown species dwelling in the depths off the coast of western Australia. the discoveries, announced by Australian scientists, include a remarkably transparent crab and a diminutive, light-emitting shark.

Deep-Sea Exploration Yields Astounding Finds

In late 2022, a team from Australia’s Commonwealth scientific and Industrial Research organisation (CSIRO) initiated a comprehensive investigation within the Gascoyne Marine Park, situated approximately 20 kilometers from the Western Australian shoreline. This region is considered a crucial hotspot for biodiversity, harboring an estimated one million distinct species, many of which are endemic to the continent.

Despite Australia’s rich biological heritage, substantial portions of its underwater environments remain largely unexplored. This lack of exploration means countless marine creatures and plant life continue to elude scientific understanding.

Introducing the new Species

The expedition successfully collected hundreds of specimens, among which were the newly identified West Australian Lantern Shark and a unique porcelain crab. The Lantern Shark, reaching a maximum length of 40 centimeters, possesses prominent eyes and generates light through bioluminescence, a phenomenon observed more than 600 meters below the ocean’s surface.

“These Lantern sharks produce their own light using photophores on their undersides and flanks,” explained Dr. Will White, a leading fish scientist involved in the project.”This bioluminescence helps them blend in with the faint light filtering down from above, offering camouflage and aiding in hunting.”

The newly discovered porcelain crab measures roughly 1.5 centimeters in length and was located at a depth of approximately 122 meters. Unlike typical crabs relying on claws for feeding, this species employs specialized hairs to filter plankton from the water.

“Porcelain crabs are interesting filter feeders,” noted Dr. Andrew Hosie, curator of aquatic zoology at the Western Australian Museum. “They use modified mouthparts with fine hairs to capture plankton, showcasing a novel feeding strategy compared to the grasping claws of most crabs.”

A Glimpse Into Australia’s Hidden Biodiversity

The 2022 voyage has already resulted in the identification of around 20 new species, including the Carnarvon Flapjack Octopus, a small, reddish creature measuring about 4 centimeters across.Experts anticipate that approximately 600 additional unique species await formal description and naming, a process that can extend over years as scientists meticulously gather and analyze data.

Australia’s commitment to marine research is exemplified by initiatives like the National Environmental Science Program’s Marine Biodiversity Hub,which invests over $138 million to understand and protect marine life. NESP Marine Biodiversity Hub

What are the potential implications of discovering new, small species like the almond-sized crab and minuscule lantern shark for understanding deep-sea food webs?

Unveiling the Biodiversity of the Abyss

Recent marine exploration efforts have yielded fascinating insights into the hidden world of the deep sea, revealing two remarkable new species: an incredibly small crab, barely the size of an almond, and a diminutive lantern shark. These discoveries highlight the vast, largely unexplored biodiversity residing in the ocean’s depths and underscore the importance of continued deep-sea research. the field of marine biology is constantly evolving, and these finds are prime examples.

The almond-Sized Crab: A New Species of Brachyura

This newly identified crab, belonging to the order Brachyura (true crabs), is notable for its exceptionally small size. While the exact species classification is still under review, preliminary analysis suggests it represents a previously unknown genus.

* Size & Morphology: Measuring just millimeters in length, this crab is among the smallest known crab species. its delicate exoskeleton and specialized appendages suggest adaptation to a specific niche within the deep-sea habitat.

* Habitat: The crab was discovered at a depth of approximately 2,500 meters (8,200 feet) in the Pacific Ocean, near hydrothermal vents. These vents provide unique chemical energy sources that support thriving ecosystems self-reliant of sunlight.

* Diet & Behavior: Researchers hypothesize the crab feeds on microscopic organisms and organic matter found near the hydrothermal vents. Its small size likely offers protection within the complex structures of the vent communities.Deep-sea crustaceans often exhibit unique feeding strategies.

The minuscule Lantern Shark: A Bioluminescent Marvel

Alongside the crab revelation, scientists also identified a remarkably small lantern shark. Lantern sharks are known for their bioluminescence – the ability to produce light – and this new species is no exception.

* Bioluminescence: the shark’s ventral surface (underside) is covered in photophores, light-producing organs, which likely serve multiple purposes, including camouflage (counterillumination), attracting prey, and dialog. Bioluminescent organisms are common in the deep sea.

* Size & Characteristics: This particular lantern shark species measures only around 15 centimeters (6 inches) in length, making it one of the smallest known shark species. It possesses the characteristic elongated body and dark coloration of other lantern sharks.

* Predatory Adaptations: Despite its small size, the shark is a capable predator, equipped with sharp teeth and a streamlined body for efficient hunting in the dark depths. Its diet likely consists of small fish, squid, and crustaceans. Deep-sea sharks have evolved unique adaptations for survival.
