5.1 Centrophorus granulosus
(Bloch & Schneider, 1801)
Squalus granulosus Bloch & Schneider, 1801: 135 (type-locality not
given). Centrophorus granulosus: Karrer, 1975: 64. Centrophorus uyato:
Bass et aI. , 1976: 31*. NOTE: We regard Squalus uyato Rafinesque , 1810
a nomen dubium, as it is uncertain even to which genus Rafinesque's
description applies and his figure is equally imprecise. Our use of C.
granulosus for this species is based on Miiller & Henle (1841) who
examined the type-specimen from Bloch's collection.
Length of 1st Dbase 9-13% TL; 2nd Dbase 7-10%; height 4-6% TL.
16-19/1/16-19
Teeth 14-17/1/14-17'
Colour grey or dark brown above, fins dark, trailing
edges pale . Attains 1.5 m. Mediterranean and both sides of
Atlantic Ocean. Our records from Walvis Bay and off
southern Mozambique are from depths of 274 - 457 m.
5.2 Centrophorus lusitanicus

Centrophorus lusitanicus Bocage & Capello, 1864: 260 (Portugal); Bass

Snout length 8.1-9.3% TL; orbit length 3.4-4.8% TL; 1st Dbase
18-21 % TL; 1st D height contained 3 times in its base; 2nd Dbase
10-12%, height 5-7% TL; teeth ~~~~~~~.
Colour dark grey or brown, slightly paler below.
Juveniles with dark fins with wide white trailing margins.
