Canary and Madeira researchers discover a new fish in Cape Verde waters - La Provincia


Canarian and Madeira researchers have discovered a new species of the fish Brótola in waters of Cape Verde, different from the other nine species found in the Atlantic.

In particular, it has been the researchers of the Research Group on Applied Marine Ecology of the University Institute for Research in Environmental Studies (i-UNAT) of the University of Las Palmas de Gran Canaria (ULPGC), José A. González and Raúl Triay-Portella, together with the Portuguese researcher of the Madeira Oceanic Observatory, Manuel Biscoito.

The discovery has been published in the international magazine Zootaxa, specialized in descriptions of new taxa (groups of related organisms) and is part of The Doctoral Thesis of Raúl Triay.

This fish differs from all his congeners by his teething, composed of large canine teeth interspersed with smaller teeth, arranged in two premaxillary series and a single mandibular series. It would be the third of this genre that lives in Cape Verde.

The new species is small, up to about 17 centimeters, and is part of the discards of the soldier shrimp fishery in Cape Verde waters, as explained by the University of Las Palmas de Gran Canaria (ULPGC) through a statement.

The experts have analyzed morphometric, meristic characters ( fins, gill rakers, vertebrae) of the ventral luminous organ and the otolith, with the rest of the family specimens of a sample of 77 specimens, of which 10 have been studied in detail and later deposited in Natural History Museums of Funchal (Portugal), London (UK), Paris (France), Washington DC (USA) and Tenerife (Spain).
