Researchers from Kerala have discovered new species of eel-loach named ‘Pangio bhujia’ in Kozhikode district of state. It is unique species of miniature well-dwelling subterranean fish. It is the first species of eel-loach in the world that has been discovered to be living in subterranean environments. Eel-loaches are generally found in fast-flowing streams in the south and the south-east Asia.
About Pangio bhujia
Discovery: It was discovered living in a six-metre-deep homestead well used for potable and irrigation purpose, as well as from channel connecting pond to an adjacent paddy field in the village of Cherinjal in Kozhikode.
Name and Genus: It has been named ‘Pangio bhujia’, due to its resemblance to the North Indian snack, bhujia. It belongs to genus Pangio.

India, China, Pakistan to work together to study impact of climate change on Hindu-Kush-Himalayan region
India Meteorological Department (IMD) is collaborating with meteorological agencies in China and Pakistan, among others, to provide climate forecast services to countries in Hindu-Kush-Himalayan (HKH) region. These countries have agreed to establish regional climate centre that will provide forecasting services and climate analyses. This centre will be under World Meteorological Organisation (WMO). It will help to better forecast impact of climate change on Hindu Kush mountains. It will take a few years to take shape. It will also provide data services, training and capacity-building, research and development.
About Hindu-Kush-Himalayan (HKH) region
It is considered the Third Pole [after North and South Poles]. It contains vast cryospheric zones and is also the world’s largest store of snow and ice outside the polar region. It spans Afghanistan, Bangladesh, Bhutan, China, India, Kyrgyzstan, Mongolia, Myanmar, Nepal, Pakistan, Tajikistan, and Uzbekistan. It traverses about 5 million square kilometres and has significant implications for climate. Recent report by Intergovernmental Panel on Climate Change (IPCC) also had highlighted threat to HKH region from global warming. It had mentioned that floods will become more frequent and severe in mountainous and downstream areas of Ganges, Indus and Brahmaputra river basins, because of increase in extreme precipitation events. It also had warned about severity of floods to be more than double towards the end of the century in this region.
