New Red Alga found in the Arabian Sea

Two new species of red seaweed - Hypnea indica and Hypnea bullata - have been discovered by marine biologists from the Central University of Punjab (The genus Hypnea includes red seaweeds.)

Hypnea indica - Discovered from Kanyakumari in Tamil Nadu, and Somnath Pathan and Sivrajpur in Gujarat.
Hypnea bullata - Discovered from the Kanyakumari and Diu islands of Daman and Diu.
Another species, Hypnea nidifica, has been found for the first time on Indian coasts.
The genus Hypnea consists of calcareous, erect, branched red seaweeds.
They grow in the intertidal regions of the coast, namely the area that is submerged during the high tide and exposed during low tides.
Species of Hypnea contain the biomolecule carrageenan, which is widely used in the food industry.
However, algae with calcareous mineral deposits are prone to damage from ocean acidification, the aftermath of climate change.
