Species Anomalocera patersoni - Plate 24 of morphological figures

Plate 24 issued from : A. Ianora, A. Miralto & S. Vanucci in Mar Biol., 1992, 113. [p.402, Fig.1, A]. SEM micrographs.
Male: A, surface attachment structure (mass of fine setules arranged in three semicircles on a flattened area of the anterodorsal surface of the cephalosome).
Nota: The structure is a complex, double horsehoeshaped formation in both copepodites and adults, the two semicircles are oriented longitudinally, with the concave surface facing each other. The general shape of this forlmation is similar in both males and females. Both semicircles consist of a thick band of setules or twisted hairs with a unramous base and branched apex with blunt ends. large pore and peg sensilla are often situated close to the structure. Not all pontellids posses this structure..
The structure is continuous with the cuticle and has no underlying sub-integumental stuctures. The main shaft of setules or hairs which emerge dorsally from the integument consists of an outer layer (epicuticule) and an inner layer (upper procuticle). The structure may be considered one of a variety of cuticular structures described for the integument of Crustacea, including the velcro-like, cincinnuli adhesions observed on some pleopod appendages of decapods and euphausiids and which apparently are involved in swimming or the hooking-type pereiopods in commensal decapod crustaceans for holding onto the host's body (Fujino, 1975) These adhesive structures are not associated with neurosecretory celles; their functions are determined by the precise shape and mechanical properties of the arthropod cuticle (Bouchon & Chaigneau, 1991)
This structure can be considered a remarkable adaptation to life on the surface. This structure presumably facilitates attachment to the surface by increasing the surface area of adhesion. According to Pennell (1973), in order to attach itself to the surface film Anomalocera opalus appears to bump upward against the film with its dorsal surface . Once the structure breaks the surface it becomes dry and apparently water-repellent

Remarks

epipelagic. Mainly surface form, sometimes observed swarming about in the surface water.
This form is often observed in the Northern Atlantic and is present in the North Sea through penetration of Atlantic waters (indicator species).
The presence seems rare in the Indian Ocean and the Pacific (see remarks in Sewell, 1948, P.432, and Silas & Pillai, 1973, p.833).
Razouls observes this species in the Toulon's harbour in 1963 (pers. comm.).
After Demir (1959) found large numbers of A. pattersoni on the northeast coast of the Aegean Sea during spring and early summer and concludes that this species is transported from the Aegean Sea to the Black Sea.; the fact that, during this period of the year, the current from the Mediterranean is more intense and that this current is subsuperficial while the species is hyponeustonic, leads to the conclusion that a transportation of Black Sea individuals to the Aegean is more plausible.
For Ianora & al. (1992, p.206) the peculiar integumental structure on the anterodorsal surface of the cephalosome appears to serve only a mechanical function and resembles no other structures described so far copepods, except some species of Pontellidae.
After Schnack (1989) the Itoh's index value of the mandibular gnathobase = 955.
