Why in News?
Researchers from Berhampur University recently recorded the rare marine amphipod Stenothoe lowryi for the first time in Indian waters at Aryapalli Beach in Odisha — a biodiversity development often discussed in UPSC coaching in Hyderabad while analysing marine ecosystems and species discovery.
About Stenothoe lowryi
Stenothoe lowryi is a small marine amphipod crustacean, resembling a tiny shrimp.
Taxonomic Classification
• Kingdom: Animalia
• Phylum: Arthropoda
• Class: Malacostraca
• Order: Amphipoda
• Family: Stenothoidae
Amphipods belong to the same broad group as crabs, lobsters, and shrimp.
Key Characteristics of Stenothoe lowryi
• Small Size: Approximately 5–6 mm in length.
• Shrimp-like Body: Possesses a laterally compressed elongated body.
• Large Claws (Gnathopods): Used for gripping rocks and capturing food.
• Adaptation to Rocky Habitats: Found mainly in rocky intertidal zones.
• Distinct Morphological Features: Unique antennae and leg structures used for species identification — characteristics often highlighted in IAS coaching in Hyderabad while studying marine biodiversity.
What are Amphipods?
Amphipods are small crustaceans found in both marine and freshwater environments.
Habitat
They inhabit diverse environments such as:
• Oceans and seas
• Rivers and lakes
• Sand beaches
• Caves and moist tropical habitats
Meaning of Amphipoda
The word “amphipoda” means “different-footed”, referring to their varied types of legs used for different functions.
Biological Features
• Amphipods have a body divided into:
• Head
• Thorax (pereon) with 7 segments
• Abdomen (pleon) with 6 segments
• Most amphipods are scavengers, feeding on organic debris and dead organisms.
Ecological Importance
• Nutrient Recycling: They break down dead plant and animal matter, helping recycle nutrients.
• Food Source: Serve as food for fish, seabirds, and marine mammals.
• Indicators of Environmental Health: Their presence often indicates healthy coastal ecosystems, an important topic covered in UPSC online coaching and civils coaching in Hyderabad while studying marine ecology.
