The new species has been named Etheostoma erythrozonum and is the first known fish species endemic to the Meramec River drainage. Its common name is Meramec Saddled Darter.
Brachypopomus gauderio is not the only electric knifefish recently described from South America, U.S. researchers John P. Sullivan* and Carl D. Hopkins** have described another member of the genus Brachyhypopomus and given it the name Brachyhypopomus bullocki.
Brazilian ichthyologists Julia Giora and Luiz Malabarba have described a new species of electric knifefish and named it Brachypopomus gauderio.
A group of conservationists and scientists are planning a research trip to the world’s largest rubbish pile; the Great Pacific Garbage Patch. Also known as the Eastern Garbage Patch, the Pacific Trash Vortex, or simply the Great Plastic Vortex; this gyre of marine litter has been gradually building over the last 60 years but we still know very little of this man-made monstrosity.
The Top 10 list of new species from 2008 has now been compiled by the ASU institute and an international committee of taxonomists. Last year, thousands of new species were described by science, many of them native to hard-to-access regions of our planet, such as remote tropical areas or deep sea habitats, but two of the species on the list actually hail from much less exotic locations: Cardiff and a bottle of hairspray.
