Context (DTE): Researchers have discovered a new species of marine amphipod, a shrimp-like crustacea of genus Parhyale.

Amphipods are a significant group in the marine ecosystem and play a vital role in the marine food chain.
They serve as indicators for studying the impact of climate change & health of coastal ecosystems.

The new species has been named Parhyale odian after Odisha’s native language, Odia, as the species was collected there.
The newly discovered species differs from all other 15 species by having a stout robust seta — a spine-like structure on the surface of the propodus of the male gnathopod (first pair of legs)
They are mostly found underneath stones with attached vegetation and also in the burrows of isopods.
