New species of labrisomidae fish discovered in Brazil

Researchers from Brazil have published data on a new species of fish in the Labrisomidae family on the Brazilian archipelago of Trindade and Martim Vaz in the Atlantic Ocean. It is an endemic species that can only be found in this group of islands due to how far it is from the coast.

Researchers from Brazil have published data on a new species of fish in the Labrisomidae family on the Brazilian archipelago of Trindade and Martim Vaz in the Atlantic Ocean. It is an endemic species that can only be found in this group of islands due to how far it is from the coast.

A team of Brazilian researchers have described for the first time a new species of labrisomid, the Hypleurochilus brasil, endemic to the Brazilian archipelago of Trindade and Martim Vaz, more than 1,200 kilometres from the coast of Rio de Janeiro in the waters of the Atlantic Ocean.

As Hudson Pinheiro, a researcher from the Department of Oceanography and Ecology at the Federal University of Espírito Santo in Brazil, explains to SINC: “Populations of this new species have been isolated in the archipelago for a long time due to the distance from the coast, and have developed clear differences in comparison with other ‘sibling’ species living on the continental margin.”

This new orange-coloured labrisomid differs from other fish of the Hypleurochilus branch because of its colour pattern, with reddish spots all over its body, the absence of dark stripes (characteristic of other labrismoids) and the dorsal, pelvic and posterior bones which form their fins. It is endemic to the Carioca archipelago of Trindade and Martim Vaz. “It is a unique species from these remote islands,” Pinheiro stresses.

"News specie has developed clear differences in comparison with other ‘sibling’ species"

Research and habitat

This new species was located in 2009 during a scientific expedition conducted by several Brazilian universities with support from the Brazilian Navy, part of the research project TAMAR/ICMbio for the conservation and study of sea turtles.

In their article, published in the journal ‘Zootaxa’, the authors describe how the Hypleurochilus brasil lives at depths of between three and fifteen metres, either alone or in small groups of up to ten. It always hides in holes or nooks on the ocean floor and is associated with various urchins and sponges that live in rocky reefs.

With the discovery of this new labrismoid, there are now eleven known members of the Hypleurochilus family in the world, three of which are found on the Brazilian coast.

A foot tumour and two tail fractures complicated the life of this hadrosaur

When it was discovered in the 1980s in Argentina, this hadrosaur was diagnosed with a fractured foot. However, a new analysis now shows that this ornithopod commonly known as the duck-billed dinosaur actually had a tumour some 70 million years ago, as well as two painful fractures in the vertebrae of its tail, despite which, it managed to survive for some time.

African crocodiles lived in Spain six million years ago

The crocodiles that inhabited the coasts of North Africa during the late Miocene period embarked on a journey to Europe across what is now the Mediterranean basin. This is confirmed by the analysis of the first fossils of the Crocodylus genus in the Iberian Peninsula, found in the Valencian site of Venta del Moro between 1995 and 2006, and which are now being described for the first time.
