Diagnosis. Scyliorhinus retifer differs from all congeners by presenting a color pattern composed of dark lines forming geometric figures and bordering the saddles (vs. lines absent in all other species); light spots absent (vs. present in all other species, except S. cervigoni , S. garmani and S. meadi ); anterior nasal flaps not reaching the upper lip (vs. flaps reaching the upper lip, and sometimes covering it in S. canicula , S. cervigoni , S. comoroensis , S. duhamelii , S. garmani , and S. stellaris ); clasper with envelope medially expanded (vs. poorly developed or absent in other species, except S. boa and S. hesperius ); cover rhipidion with no dermal denticles (vs. denticles present in other, except in S. boa , S. cervigoni and S. hesperius ). The following combination of characters, although less conspicuous, also helps distinguish this species: nasoral grooves absent and anterior nasal flaps situated on the posterior border of excurrent apertures (vs. grooves present and flaps situated laterally in S. canicula and S. duhamelii ); mesonarial ridge not exceeding the posterior border of anterior nasal flaps (vs. exceeding in S. stellaris ); interdorsal distance greater than anal base (vs. smaller or similar to anal base in S. canicula , S. capensis , S. cervigoni , S. comoroensis , S. duhamelii , S. garmani , S. stellaris , and S. torazame ); oral canal of lateral line system with 8–10 pores (vs. 5–6 in S. hesperius ; 10–12 in S. duhamelii ; 9–13 in S. torrei ); commissural teeth with two cusplets (vs. one in S. cervigoni , S. torazame and S. torrei ; three or more in S. boa , S. canicula and S. hesperius ); pelvic apron extending to 2/3 of length of pelvic inner margins (vs. extending through almost entire length in S. canicula , S. capensis , S. duhamelii , S. torazame , and S. torrei ); clasper terminal dermal cover smooth (vs. rough in S. canicula and S. capensis ); terminal 3 cartilage present (vs. absent in other species, except in S. boa , S. canicula , S. capensis , and S. torazame ); dorsal terminal 2 cartilage elongated and rodlike, corresponding to 1/4 of dorsal terminal cartilage (vs. reduced and subtriangular in S. cabofriensis , S. capensis , S. cervigoni , S. haeckelii , and S. ugoi ; 1/3 of dorsal terminal cartilage in S. boa and S. comoroensis ; cartilages the same length in S. torazame ); neurocranium width across nasal capsules smaller than nasobasal length (vs. greater in S. meadi ); nasal capsule width 0.9–1.2 times its length (vs. 1.4 times in S. meadi ); counts of monospondylous vertebrae 37–43 (vs. 44–46 in S. capensis ; 35–37 in S. duhamelii ; 48 in S. garmani ; 46–48 in S. meadi ; 43–47 in S. stellaris ; 30–35 in S. torrei ); adult males between 395–580 mm TL and adult females 380–590 mm TL (vs. adult sizes greater than 600 mm TL in S. capensis , S. cervigoni , S. meadi , and S. stellaris ; 269 mm TL and 294 mm TL, respectively, in S. torrei ).

Lines not very distinct in region anterior to spiracles; triangles situated anterior to eyes. Light brown lines, crossed by narrow black stripes, uniting with other lines and forming a web of polygons. Unique dark line between predorsal and first dorsal saddles and interdorsal and second dorsal saddles; one line between spiracles. Subsaddles between saddles anterior to the first dorsal fin. Individual variation in relation to geometric patterns present, mainly in the anteriormost saddles (branchial, pectoral and predorsal). Dark or light spots usually absent; when present, spots dark and greater than spiracles, continuous to lines. Belly and ventral surface of paired and anal fins without lines, cream in color.
Distribution. This species is widely distributed, known to occur from the Gulf of Mexico, from off Campeche, Mexico (95°W) to Florida (83°W), to the northeast coast of United States, from Georgia (30°N) to Connecticut (41°N) ( Fig. 69 View FIGURE 69 ).
Biological data. Adult males examined 395–580 mm TL; largest male examined 513 mm TL. Adult females between 380–590 mm TL; largest female examined 520 mm TL. Specimens from northern regions present greater sizes at maturity than those from southern regions ( Castro et al. 1988; Sminkey & Tabit 1992). Maximum size recorded 590 mm TL. Newly born specimens between 100–110 mm TL.
Females can store sperm through extended periods, producing viable eggs without males for two years or more. Egg capsules deposited in pairs in 8 to 15 days in captivity, during spring and summer, about 44 to 52 eggs per year ( Castro et al. 1988; Compagno et al. 2005). Castro et al. (1988) presents descriptions of the mating process and embryonic development. Egg capsules amber to dark brown with golden edges ( Fig. 19C View FIGURE 19 ). Anterior edge nearly straight and wider with strong tendrils on lateral sides; tendrils crossed at posterior edge. Longitudinal lines along the egg capsule present; lateral walls reinforced and without striae. Mean values of egg capsule dimensions: 51.9 mm in length, 21.6 mm in width, and 10.2 mm in height (n = 11).
Stomach contents include squid beaks, bony fishes, polychaetas, annelid worms and crustaceans. A preponderance of squid remains suggests that, even presenting a sluggish habit, this species is probably an ambush predator ( Ford 1921).
This species is a benthic dweller in depths of 73– 550 m. It is apparently more abundant in deeper waters off Virgina and North Carolina; specimens have been captured in shallower waters (50–220 m) in the northern regions and in deeper waters (230–450 m) in Cape Hatteras. In comparison with males, females have been recorded in deeper waters in the north (91–457 m vs. 38–405 m for males) and in shallower waters at the south (73–512 m vs. 239–795 m for males). Adults prefer rocky bottoms and juveniles remain on sandy bottoms. This species presents no interest to fisheries. Its distribution seems to be irregularly interrupted in areas where adults are rare; its preference for rough bottom habitats is generally considered by fishermen as not suited for trawling. Egg laying may be concentrated in specifically limited nursery areas. This species occurs in temperatures 8.5° to 11.3° C ( Springer 1979; Ebert & Stehmann 2013). Species frequently exhibited in aquariums of the United States. Conservation status ‘Less concern’ with increasing population trend (Sherrill-Mix et al. 2006).
Etymology. The specific name ‘retifer’ refers to its unique reticulated color pattern.
Remarks. Scyliorhinus retifer presents a reticulated color pattern, similar to Cephaloscyllium fasciatum . It is distinguished from C. fasciatum by presenting a flap on upper lip margin that is laterally projected and covers the lower labial furrow (vs. absent in C. fasciatum ), postoral groove absent (vs. present), dorsal fins more posteriorly situated, and males with pelvic apron extending to 2/3 of length of pelvic inner margins (vs. pelvic apron absent).
The type locality given by Springer (1979), as situated in Virginia, consisted in an error as noted by Hartel & Dingerkus (1997); mapping of the geographical coordinates points to the type locality being Delaware as related by Garman (1913). Records for the San Andrés Archipelago, Providencia, and Catalina in the Western Colombian Caribbean, probably refer to S. boa ( Bolaños-Cubillos et al. 2015) . Material previously identified as a subspecies of S. retifer ( Springer & Sadowsky 1970) was examined and reidentified by us, updating data on the geographic distribution of this species (see Appendix). Thus, S. retifer is restricted to the eastern coast of United States and Gulf of Mexico, with its southernmost record the southwestern coast of Mexico (18°N), not overlapping with S. boa and S. hesperius .
