New Viper Species discovered by Indian Herpetologists in Arunachal Pradesh

The Indian Herpetologists discovered new species of viper family in the Pakke Tiger Reserve in Arunachal Pradesh. It has been named after a fictional character, Salazar Slytherin.


This is the second species of viper that was discovered in Arunachal Pradesh. However, there are more 48 species of viper in the region (across South East Asia and East Asia). It is very difficult to spot in Arunachal Pradesh. Also, the biodiversity documentation in the state is bad.


Vipers are venomous snakes that are found in almost all parts of the world. They are not found in Australia, Antarctica, Hawaii, New Zealand and Madagascar. They have a pair of long fangs that inject venom. These snakes are intelligent and have the capability to decide how much venom to inject based on the circumstances.

Pakke Tiger Reserve

The Tiger Reserve is bounded by Kameng river in the west and north and by Pakke river in the east. It is located in Arunachal Pradesh.

BRO: Daporijo Bridge across Subansiri river in Arunachal Pradesh inaugurated

On April 20, 2020, the Chief Minister of Arunachal Pradesh Pema Khandu inaugurated a bridge across the Subansiri river. The bridge was constructed by the BRO (Border Roads Organization).


The developmental work of the Daporijo bridge was undertaken by the BRO amidst lock down. The bridge is of great importance as its links roads leading to India-Arunachal Pradesh border. The bridge was constructed in less than a month sticking to the safety precautions.

The bridge had developed cracks and caused accident in 1992. A bus fell off the bridge and none of the passengers survived the accident. The new bridge constructed can withstand 40 tonnes of weight.


The bridge is of great importance as the ration supplies, medicines and constructional materials pass through this bridge. Also, it is important for the transit of Indian Army as India and China have not demarcated their borders. This is important as China has motorable roads so close to Indian border.

Subansiri river

Subansiri river is a tributary of Brahmaputra river. It runs through the states of Tibet and Arunachal Pradesh. The river originates in China. It joins Brahmaputra in Assam.
