hectocotylhectocotylen.

/hɛktəʊˈkɒtɪl/

Forms: Also in Latin form hectocotylus.

Etymology: < modern Latin Hectocotylus, name given by Cuvier to what he took for a genus of parasitic worms (see definition below), < hecto- comb. form + Greek κοτύλη small cup, hollow thing (compare cotyle n. 2b).

Zoology.

A modified arm in male dibranchiate Cephalopods, which serves as a generative organ, and in some species is detached and remains in the pallial cavity of the female; in this position formerly mistaken for a parasite, to which the name Hectocotylus octopodis was given by Cuvier.

hectocotyl1851

1851 S. P. Woodward Man. Mollusca i. 65 Dr. Albert Kölliker has suggested that the real males..are the hectocotyles, previously mistaken for parasitic worms. The hectocotyle of octopus granulatus was described by Cuvier, who obtained several specimens from octopods captured in the Mediterranean.

1877 T. H. Huxley Man. Anat. Invertebrated Animals viii. 538 The male is very much smaller than the female, and gives rise to a Hectocotylus.

Derivatives

hectoˈcotylize v. (transitive) (a) to convert or modify into a hectocotyle; (b) to impregnate with a hectocotyle.

1870 H. A. Nicholson Man. Zool. 272 The arm so affected..is said to be ‘hectocotylised’.

1877 T. H. Huxley Man. Anat. Invertebrated Animals viii. 530 The male Cephalopods are distinguished..by the asymmetry of their arms, one or more of which, on one side, are peculiarly modified, or hectocotylised.

1878 F. J. Bell & E. R. Lankester tr. C. Gegenbaur Elements Compar. Anat. 327 This ‘hectocotylised arm’ is not developed, as are the others, by a process of free gemmation, but it is formed in a vesicle, from which it is not let loose till it is mature.

hectocotyliˈzation n. the process of hectocotylizing.

1877 T. H. Huxley Man. Anat. Invertebrated Animals viii. 534 There is thus a kind of hectocotylisation in the Tetrabranchiata.
