Data on three Baltic species of Corynosoma Lühe, 1905 (Acanthocephala: Polymorphidae) from Baltic grey (Halichoerus grypus) and ringed seals (Pusa hispida)
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 usin...

| Summary: | 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). Table 1 Material studied with the Proboscis Profiler (M= male). Figure 1 Proboscis profiles of male Corynosoma magdaleni and C. semerme. a. Length. b. Base. Proboscis profiles generated using a moving average interval of 20%. Profile labels are comprised of three parts: species, surface of proboscis (dorsal, lateral or ventral) and a numerical identifier for the acanthocephalan specimen. N.B. profiles for C. magdaleni (dorsal and ventral) are from a single specimen. Figure 2 Result of the principal component analysis of the proboscis profiles of male Corynosoma magdaleni and C. semerme. Figure 3 Meristogram for Corynosoma semerme. Graph shows serial variation in four hook morphometrics: L: length; B: base width; A: area; R: ratio. Meristogram generated with a moving average interval of 20%, using data from two females and eight males. Supplementary Material 1 Row data of the measurements of the Baltic Corynosoma semerme Proboscis Profiler. Supplementary Material 2 Row data of the measurements of the Baltic Corynosoma magdaleni Proboscis Profiler. Notation used for the accession number in both supplementary materials: species (s for semerme, m for magdaleni) - sex - surface of proboscis (d=dorsal, v=ventral, l=lateral) - host (g=grey, r=ringed) - specimen number For example, s-m-d-g-1 denotes a dorsal row of hooks from a male specimen of Corynosoma semerme which was collected from a grey seal and given the ID "1" References Aznar FJ, Bush AO, Fernández M, Raga JA (1999) Constructional morphology and mode of attachment of the trunk of Corynosoma cetaceum (Acanthocephala: Polymorphidae).
