We analyzed Baltic Corynosoma material (C. magdaleni Montreuil, 1958, C. semerme (Forssell, 1904) Lühe, 1911 and C. strumosum (Rudolphi, 1802) Lühe, 1904) from grey (Halichoerus grypus) and ringed seals (Pusa hispida) for the variation of hook morphology and for finding possible morphotypes, by using the proboscis profiler (Wayland 2010) and Meristogram (Wayland 2016). ... : Methods: All data analysis was performed using the R language and environment (R Core Team 2019). For species names we followed the nomenclature given by the Catalogue of Life (2019 Annual Checklist: Roskov et al. 2019) and WoRMS (WoRMS Editorial Board 2020). The studied seals were collected during Swedish grey and ringed seal hunting in 2007-2008 in different parts of the Baltic Sea (Table 1). The thorny-headed worms were collected during the autopsy at the Swedish Museum of Natural History (for more details see Leidenberger et al. 2019). The worms have been preserved in 70% alcohol. Voucher material is deposited in the invertebrate collection of the Department of Zoology, Swedish Museum of Natural History (SMNH), Stockholm, Sweden (# SMNH-162973-162978, SMNH-172304-172310). Additionally, specimens of C. magdaleni collected by Nickol et al. (2002) from the Finish Baltic Sea, were borrowed from the University of Nebraska State Museum, Manter Laboratory of Parasitology (# HWML 39480). Here, we tested the ...
