A new species of Antarctic dragonfish, Akarotaxis gouldae or Banded Dragonfish, has been discovered in waters off the western Antarctic Peninsula by researchers at William & Mary’s Virginia Institute of Marine Science (VIMS). The species, named in honor of the recently decommissioned Antarctic research and supply vessel (ARSV) Laurence M. Gould and its crew, exemplifies both the unknown biodiversity and fragile state of the Antarctic ecosystem.
Described in the journal Zootaxa, Akarotaxis gouldae was initially identified through genetic analysis. Larval specimens collected off the coast of Antarctica while trawling for zooplankton were originally thought to be Akarotaxis nudiceps, a closely related dragonfish. However, after comparing their DNA to Akarotaxis nudiceps specimens housed in collections at VIMS, Yale University and the Muséum national d’Histoire naturelle in Paris, France, significant variations in mitochondrial gene regions suggested the larval samples were a species unto themselves.
Lead author Andrew Corso conducted the research while earning his Ph.D. at W&M’s Batten School of Coastal & Marine Sciences at VIMS under faculty advisors Eric Hilton and Deborah Steinberg. Using the DNA evidence as their guide, Corso and his colleagues requested the examination of adult Akarotaxis gouldae samples from numerous ichthyology collections around the world. Morphological differences became apparent between the two species once the adult samples were compared.
