Short Description
Diagnosis after Compagno, 1984 [517]: Field Marks : A large, fairly stocky, catshark with large and small black spots and sometimes white spots covering dorsal surface, saddle markings obsolete, small anterior nasal flaps that do not reach mouth, no nasoral grooves, labial furrows on lower jaw only, second dorsal fin much smaller than first. Diagnostic Features : Head and body moderately broad. Greatest width of head about 2/3 of head length; no nasoral grooves; anterior nasal. flaps not expanded and falling just short of mouth. First dorsal origin opposite pelvic insertions; second dorsal origin well anterior to anal insertion; interdorsal space subequal or less than anal base. Denticles fairly large and semierect, surface of skin relatively rough. Colour pattern of numerous small and large black spots sometimes interspersed with white spots, the large spots often irregular, subangular, and sometimes expanded into large blotches that may totally cover the body in some individuals; saddle markings indistinct or absent. Size large, adults to 1.6 m.

Distribution
Balearic and Tyrrhenian Seas, in the continental shelves of Italy, Tunisia, France and Spain, with two records in the Adriatic Sea close to Venice, Italy, and Rovinj, Croatia. Also found along the Northeastern Atlantic in the continental shelves of Portugal, France and the United Kingdom, as well as one record for the North Sea (55ºN, 3ºE). No records exist from northwestern Africa [27296] Source: www.gbif.org

fisheries: minor commercial; aquarium: public aquariums; price category: medium; price reliability: reliable: based on ex-vessel price for this species

Biology
Oviparous, with a single egg per oviduct [517]. Embryos feed solely on yolk [733]. Size at hatching about 16 cm [517].

Size / Weight / Age
190 cm TL (male/unsexed; [27296]); max. reported age: 19 years (Ref. 72467)

Habitat
reef-associated; marine; depth range 1 - 400 m [17657], usually 20 - 63 m [517]

Dentition
Monognathic heterodonty gradual well developed; anterior teeth abruptly larger than the parasymphysial ones and lateral teeth smaller distally, with smaller and thicker principal cusps (Fig. 73). Sexual heterodonty pronounced with females presenting shorter principal cusp and more developed cusplets than males. Tooth counts 20–26 16–25/16–25 0–1 16–24. Parasymphysial teeth with a principal cusp flanked by one cusplet on each side; cusplets half the height and the width of the principal cusp. Protuberances on medial portion of the crown base and striae restricted to the crown base. Anterior teeth larger than the parasymphysial and principal cusp less stout. Anterior teeth with two to four cusplets; marginal cusplets poorly developed and 1/3 the height of proximal cusplets in upper teeth and poorly developed in lower teeth. Proximal cusplets 1/3 the height and the width of the principal cusp in teeth in both jaws. Protuberances on the crown base and striae extending to one half the height of crown. Lateral teeth with three cusplets; principal cusp slightly oblique, two cusplets at the mesial edge and one at the distal edge. Mesial proximal and distal cusplets one halt to 2/3 the height of the principal cusp; mesial marginal cusplet half the height of proximal one. Protuberances on the crown base and striae running from base toward the apex of the principal cusp. Commissural teeth with two cusplets; principal cusp stronger and laterally situated. Cusplets 2/3 the height and the width of the principal cusp. Protuberances on the crown base and striae throughout the crown. Ectodermal pits present in lateral and commissural teeth, restricted to the crown base. [27296]
