Abstract

Zoarcidae (eelpouts), including 298 recognized valid species, is the most diverse family in the suborder Zoarcoidei (order Perciformes). Many of the species exhibit a great degree of phenotypic plasticity. In the present work, we analyze the genome of six Arctic species from the most diversified zoarcid genus Lycodes (L. eudipleurostictus, L. paamiuti, L. pallidus, L. seminudus, L. squamiventer, and L. reticulatus) providing the first information on the species-specific karyotype and pattern of major ribosomal genes chromosomal localization. The study revealed an unexpected consistency of the chromosomal features across species that apparently contrasts with the high level of inter-specific and intra-specific plasticity of morphological characters. The comparison between the chromosomal features of these Arctic eelpouts with those of the Antarctic species Lycodichthys dearborni (same subfamily, Lycodinae), suggests a conservative organization of the genome, at the level of gross architecture of chromosomes and karyotypes, within the family Zoarcidae.
