Whole-genome sequencing suggests taxonomic inflation in the Careproctus snailfishes (Liparidae) of the northeast Atlantic-Arctic region
As Arctic Ocean temperatures rise, shifts in fish species composition and distribution highlight the need for accurate classification to support conservation efforts. Careproctus snailfishes, common in the region, face taxonomic challenges due to reliance on morphological traits. Using mitochondrial DNA and nuclear SNP data, this phylogenomic study found limited support for more than two distinct species, emphasising the importance of integrating genetic methods with morphology to avoid taxonomic inflation. Additionally, the study confirmed the presence of C. micropus in northern Norway, extending its known range.
