Evaluation of Differences between the Baltic Triglopsis quadricornis and White Sea Triglopsis sp. Using Morphological and Genetic Data

According to the modern fish system, one species of fourhorn sculpin Triglopsis quadricornis lives in Baltic Sea and Arctic waters. In present study, sculpins from White Seas were studied using different methods: morphological analysis establish patterns seismosensory tomography for study cranial bones, X-ray imaging axial skeleton, as well phylogenetic two mtDNA markers (control region CO1) nDNA marker (RAG1). The results obtained by these methods used prove existence species: T. sp. Sea. These differ significantly unique shape size bony outgrowths on head, number plates body. Genetic differences between expressed formation independent clusters Bayesian trees reconstructed based sequences control RAG1.
