In 2026, marine science in India received exciting news with the discovery of a rare marine amphipod species called Stenothoe lowryi. This shrimp-like crustacean was recorded in Indian coastal waters for the first time, marking an important addition to the country’s marine biodiversity database. The discovery was made by researchers from Berhampur University during a field survey along the Odisha coast.
The presence of Stenothoe lowryi in India is significant because the species had previously been reported only from Malaysian waters. Its identification in the Bay of Bengal region expands the known geographical distribution of this marine organism and highlights how much of India’s coastal biodiversity still remains unexplored.
This blog explains the discovery of Stenothoe lowryi, its characteristics, habitat, scientific importance, and what it means for marine biodiversity research in India.
Discovery of Stenothoe lowryi in India
The rare marine amphipod Stenothoe lowryi was discovered at Aryjapalli Beach in the Ganjam district of Odisha during a coastal biodiversity survey. The research team collected multiple specimens from rocky intertidal habitats along the shoreline.
The discovery was led by Dr. Shesdev Patro, an Assistant Professor in the Department of Marine Sciences at Berhampur University. The project was funded through the Mukhyamantri Research Innovation Extramural Programme (MRIEP) of the Odisha State Higher Education Council.
During the survey, scientists collected eight specimens from rocky coastal environments. After careful microscopic examination and taxonomic analysis, the specimens were confirmed to belong to the species Stenothoe lowryi. This finding represents the first recorded presence of the species in Indian waters, making it an important scientific milestone.
The results of the study were later published in the Journal of the Marine Biological Association of the United Kingdom, an internationally recognized peer-reviewed journal.
What is Stenothoe lowryi?
Understanding Stenothoe lowryi discovered in Indian waters
Stenothoe lowryi is a small shrimp-like marine crustacean belonging to the amphipod group. Amphipods are tiny invertebrates related to crabs, lobsters, and shrimp and are commonly found in marine ecosystems across the world.
Key biological details include:
Scientific name: Stenothoe lowryi
Family: Stenothoidae
Order: Amphipoda
Size: Approximately 5.5 mm in length
Habitat: Rocky intertidal marine environments
Distinctive feature: Large claws known as gnathopods
These claws help the organism grip rocks and substrates while feeding or moving through coastal habitats.
Before this discovery, the species had been documented only in Malaysia, particularly around the Straits of Malacca, where it was formally described in 2023.
The identification in India therefore represents an expansion of the species’ known distribution.
What Are Amphipods?
To understand the importance of this discovery, it is useful to know more about amphipods.
Amphipods are a group of small crustaceans found in oceans, freshwater bodies, beaches, caves, and moist environments. Their name comes from the Greek word meaning “different-footed,” because they possess several types of legs adapted for various functions such as walking, swimming, and grasping food.
Important facts about amphipods include:
Over 7,000 known species worldwide
Sizes range from 0.1 cm to several centimeters
Commonly called “scuds” or “beach fleas”
Play a vital role in aquatic food chains
They serve as decomposers, scavengers, and prey for fish and other marine animals, making them essential components of marine ecosystems.
Habitat and Distribution
The newly discovered Indian specimens of Stenothoe lowryi were found in rocky intertidal habitats along Aryjapalli Beach in Odisha. These coastal zones are areas where the ocean meets land and are alternately submerged and exposed due to tidal movements.
Such habitats are ideal for amphipods because they offer:
Rocky surfaces for attachment
Algae and organic matter for feeding
Shelter from predators
Nutrient-rich water flow
The Odisha coast, particularly the Bay of Bengal region, is known for its biodiversity due to nutrient-rich waters and varied coastal ecosystems.
The discovery suggests that the eastern coast of India may host many undocumented marine invertebrates, encouraging further scientific exploration.
Scientific Importance of the Discovery
The recording of Stenothoe lowryi discovered in Indian waters has several scientific implications.
1. Expansion of Species Distribution
The species was previously known only from Malaysian waters. Finding it in India indicates that its distribution range is broader than earlier believed.
2. Biodiversity Documentation
Every new species record helps scientists build a clearer understanding of marine biodiversity in the Indian Ocean.
3. Improved Ecosystem Studies
Amphipods are essential components of marine food webs. Identifying new species helps researchers better understand nutrient cycling and ecological interactions.
4. Marine Conservation Awareness
Discoveries like this highlight the need to protect coastal ecosystems from pollution, climate change, and habitat destruction.
Role of Berhampur University in Marine Research
Berhampur University in Odisha has played a significant role in marine biodiversity research along India’s eastern coastline.
The institution’s Department of Marine Sciences has conducted extensive surveys since 2010, documenting several amphipod species.
Previous discoveries by the research team include:
Grandidierella geetanjalae (discovered in Chilika Lagoon)
Parhyale odian (documented from Barkul region)
These findings demonstrate the importance of regional universities in contributing to global marine science research.
The discovery of Stenothoe lowryi adds another significant achievement to this list.
Ecological Importance of Stenothoe lowryi
Although research on the species is still ongoing, scientists believe that Stenothoe lowryi plays an important ecological role.
Potential ecological contributions include:
Breaking down organic matter in coastal ecosystems
Serving as food for fish, seabirds, and larger invertebrates
Maintaining nutrient balance in marine habitats
Amphipods generally function as grazers and scavengers, helping to recycle nutrients within ecosystems.
Because they are sensitive to environmental changes, amphipods are also considered important indicators of ecosystem health.
Marine Biodiversity Along the Odisha Coast
The discovery also highlights the biodiversity richness of Odisha’s coastline, which stretches nearly 480 kilometers along the Bay of Bengal.
Important marine habitats in the region include:
Rocky shores
Sandy beaches
Estuaries
Lagoons such as Chilika Lake
These ecosystems support thousands of marine organisms, including fish, crustaceans, mollusks, and migratory birds.
However, these habitats also face threats such as:
Coastal pollution
Plastic waste
Climate change
Habitat destruction
Therefore, scientific discoveries like Stenothoe lowryi discovered in Indian waters emphasize the need for sustainable marine conservation policies.
Future Research Directions
The discovery opens the door to several research possibilities.
Scientists are planning further studies to understand:
The species’ genetic diversity
Its feeding behavior
Reproductive biology
Ecological interactions
Possible presence in other Indian coastal regions
Researchers are also conducting molecular and ecological analyses to better understand the species’ evolutionary relationships and habitat preferences.
Future marine biodiversity surveys may reveal additional undiscovered amphipod species in Indian waters.
