New Fish Species Latest News
In a significant scientific breakthrough from Northeast India, researchers recently described two new species of freshwater fish named Glyptothorax sentimereni and Oreichthys elianae from Nagaland.
About Glyptothorax sentimereni and Oreichthys elianae
- They are two new species of freshwater fish.
- They were discovered during ichthyological surveys in tributaries of the Brahmaputra River in the Mokokchung district, Nagaland.
Glyptothorax sentimereni
- It was discovered in the rocky stretches of the Dikhu River.
- It belongs to a group of torrent-dwelling catfishes known for their ability to cling to fast-flowing streams.
- It possesses a specialised adhesive structure on its underside that helps it cling to rocks in strong currents.
- It also possesses serrations on its dorsal-fin spine and a plicate (folded) ventral surface on its pectoral and pelvic fins — features that separate it from closely related species across the Ganges–Brahmaputra–Meghna basin.
Oreichthys elianae
- It was found in a tributary of the Tsurang River.
- Measuring just over 2.5 cm in length, the tiny fish is distinguished by its bright red fins and a prominent black blotch at the base of its tail.
- It has an incomplete lateral line with only five pored scales and 14–15 pores on the cheek.
