Cantherhines pullus (Ranzani, 1842) , orange-spotted filefish

Material examined. – No voucher specimens. One individual caught on a fish trap and photographed, and then identified by an expert. An adult, approximately 114 mm TL, off Castillo del Romeral, 27°47’N 15°27’W, 18-30 m, 14 Jan. 2015, rocks ( Fig. 2K ) .

Sightings and catches. – Once, n = 1, same locality ( Fig. 3 ).

Remarks. – A subtropical reef-associated species, living from 3 to 50 m of depth ( Harmelin-Vivien and Quéro, 1990), usually at 3-20 m ( Gasparini and Floeter, 2001). Found in shallow water and around coral and rocky reefs (Tyler, 1978). Usually remains near the bottom, hiding among gorgonians and branching coral ( Lieske and Myers, 1994). Feeds on bottom growth, primarily sponges and algae, but stomachs often contain tunicates, bryozoans and other sessile benthic invertebrates ( Böhlke and Chaplin, 1993). Young are pelagic and highly important food items in the diet of large predaceous fishes such as tunas and billfishes (Tyler, 1978). Maximum length published is 200 mm TL ( Robins and Ray, 1986). An amphi-Atlantic species. West Atlantic: known from Massachusetts, USA and Bermuda to southeastern Brazil ( Harmelin-Vivien and Quéro, 1990), including Trindade Island ( Gasparini and Floeter, 2001). East Atlantic: off some Gulf of Guinea islands ( Harmelin-Vivien and Quéro, 1990), São Tomé and Príncipe ( Osório, 1891; Afonso et al., 1999; Wirtz et al., 2007) and Annobón ( Wirtz et al., 2007). Absent from the Cape Verde Islands ( Wirtz et al., 2013).

This is the first record for C. pullus from the Canary Islands.
