BELEM, Brazil — A series of expeditions to explore the unknown biodiversity of the forests of the northern margin of the Amazon River in Brazil yielded a new species of catfish, researchers from Brazil announced today. Published in the journal Zootaxa in January, the discovery was made in a tributary of the Amazon River, in the northern state of Pará, at the heart of the world’s largest block of protected rainforest, which covers four million hectares.
Named after the Mayan word “Ix”, which is a term used to describe jaguars, the new fish, Stenolicnus ix, differs from other species of the same genus by the length of the nasal barbels, or the slender, whisker-like tactile organs extending from the mouth.
