Description
* Contracaecum osculatum (Rudolphi, 1802) Baylis, 1920 (sensu lato)
Includes: * C. osculatum A auct.; * C. osculatum B auct.; and * C. osculatum C auct.
Description (after J. W. Smith & Wootten 1984c, and Moravec 2013). NB: the following description applies also to
* Phocascaris sp. and/or * Contracaecum sp. (see below). Greenish brown in colour, sometimes tinged with red, L3
about 7 to 30 long, lying coiled in capsules of irregular shape (J. W. Smith & Wootten 1984c). Mouth, lips, boring
tooth, and excretory pore similar to those of Anisakis simplex L3 (see Fig. 73 A,B,C).
According to Moravec (2013), L3 are 3.81–22.00 long, maximum width 0.15–0.53. Oesophagus 0.55–1.71 long,
ventricular appendix 0.54–1.58, and intestinal caecum 0.20–0.89. Single excretory cell extends posteriorly to mid-
body region. Tail 0.09–0.21 long, narrows rapidly to a point lacking a mucron. Anterior and posterior ends of an L3
shown diagrammatically in Fig. 75 A,B.
Sites: intestinal lumen, mesenteries, musculature, viscera
Hosts: Boreogadus saida (13); Gadus macrocephalus (11); Gadus morhua (1, 4, 5, 7, 8, 9, 10, 14, 16); Glyptocephalus cynoglossus (1); Hippoglossoides platessoides (10); Hippoglossus hippoglossus (11); Mallotus villosus (10); Myoxocephalus scorpius (10); Oncorhynchus mykiss (6); Oncorhynchus tshawytscha (12); Pseudopleuronectes americanus (10); Theragra chalcogramma (11); Urophycis tenuis (5, 15); unspecified “fish” (2, 3)
Distribution: Atlantic, Nunavut, Pacific
