Sightings and catches . – Three times, n = 5: dike Reina Sofía, 21 m , rocky breakwater; off La Isleta, 19-37 m , rocks ( Fig. 3 ). Remarks. – A tropical demersal species, living from 5 to 200 m of depth ( Desoutter, 1990 ), usually at 5-40 m , between 20 and 25°C ( Baensch and Debelius, 1997 ). Found on rocky and coral bottoms ( Schneider, 1990 ). It is also a brackish coastal species found in the mouth of rivers and lagoons ( Desoutter, 1990 ). Feeds on zooplankton, phytoplankton and detritus ( Diouf, 1996 ). Maximum length published is 450 mm SL ( Randall, 1981 ). It is firstly an eastern Atlantic species: from Portugal ( Costa and Gonçalves, 2013 , at 38.43°N in December 2007 ) and Morocco to Angola , including the Cape Verdes ( Franca and Vasconcelos, 1962 ; Wirtz et al. , 2013 ; Hanel and John, 2015 ) and São Tomé Island ( Osório, 1891 ; Afonso et al. , 1999 ; Wirtz et al. , 2007 ). Recently reported from the West Atlantic: Brazil ( Luiz-Júnior et al. , 2004 ). A. monroviae was first reported from the Canaries by Brito (1991) based on five individuals caught at the Port of Santa Cruz de Tenerife. Brito et al. (2002) reported on several sightings and another four individuals caught in Gran Canaria. One more observation was reported off El Cabrón Beach in August 2014 by Espino et al. (2014) .
