From Marine Species Identification
(Vérany, 1839)

Description
Adult. Swift nektonic squid with a muscular mantle, large head and strongarms. Mantle length up to 29 cm. Mantle width is 17-25 % of mantle length. Fin is terminal, rhomboidal and wide. Arms bear two rows ofsuckers with denticulate rings. Suckers of lateralarms in males are conspicuously enlarged. Length of the longest arm in males is 55-90 % of the mantle length, in females 48-57 %. The widened club bears 8 transverse rows of suckers at the end of the club. Suckers of the middle rows in the central part of the club are greatly enlarged.
Young. Ocular or visceral photophores absent. Tip of proboscis withsuckers that are nearly equal in size; length of proboscis is typically 50-75% of the mantle length (4-8 mm mantle length). The proboscis begins to divide at about 4 mm mantle length, and the tentacles separate by 10 mm mantle length. Postproboscis of the young is characterised by the presence of morre than four rows of suckers on the dactylus and many closely packed suckers and/or suckerbuds. [After Wormuth et al., inSweeney et al., 1992].

Size
Adultmantle length up to 30 cm.

Helminth parasite of Illex coindetii (Cephalopoda: Ommastrephidae) off the Galician coast (NE Atlantic)
S. PASCUAL, B. LORES, C. ARIAS, A.GONZÁLEZ, Á. GUERRA 2015 (Full article)
Introduction
The squid Illex coindetii is a monocyclic species inhabiting mainly te far-neritic waters along the coasts of the North-eastern Atlantic Ocean. It has recently acquired a major commercial importance in the Atlantic waters off Spain where it is one of the key functional elements of the pelagic community (GONZÁLEZ et al. , 1992). As HOCHBERG (1990) highlighted, evidence indí- cales that cephalopods play a similar role to carnivorous fish species in the transmission of parasites in the sea. In addition to the taxonomic and public health significance of the worms (SMITH and WOOTTEN, 1978), characterisation of cephalopod parasites * Received April 4, 1993. Accepted September 3, 1993. is of considerable importance owing to the feasibility of using parasites as biological tags in squid population studies (BOWER and MARGÓOS, 1990). Prior to this study, no information was avalaible in the literature on cephalopod parasites found in waters off Spain. The aim of this article is to establish the identity of helminth parasites present in Illex coindetii. Once the identity of the intestinal helminths is established, they could be used as biological markers to speculate on the biotic and trophic relationship of Illex coindetii on the Galician coast.
