About Sheathia meghalayensis:
- It is a new species of freshwater red algae.
- It was discovered near Crinoline Waterfalls in East Khasi Hills, Meghalaya.
- Freshwater red algae are highly sensitive organisms that act as critical bioindicators of pristine, undisturbed aquatic ecosystems.
- Such algae thrive only in clean, oxygen-rich freshwater, making them important indicators of healthy river ecosystems.
- They are also known to produce bioactive compounds with antiviral, antioxidant, anti-inflammatory, and anti-tumour properties.
- Members of this group are also valued for compounds used in pharmaceuticals, nutrition, and biotechnology.
- Previously, only two species of Sheathia (Sheathia indonepalensis and Sheathia assamica) had been discovered from the Northeast, both in Assam.
- The researchers have proposed that Sheathia meghalayensis be classified as Critically Endangered.
