“…Aspistor is very common on the north (Barletta, Barletta‐Bergan, Saint‐Paul, & Hubold, ; Barros, Torres, & Frédou, ; Barthem, ; Camargo & Isaac, ; Castro, ; Hercos, ; Martins‐Juras, Juras, & Menezes, ; Piorski, Serpa, & Nunes, ; Silva, Santos, Travassos, & Vianna, ) and the southeast coasts (Andrade‐Tubino, Ribeiro, & Vianna, ; Andreata et al., ; Corrêa, ; Queiroz, Spach, Sobolewski, Santos, & Schwarz, ; Vilar et al., ), but much rarer in intermediate areas of the eastern/northeastern coast (Andrade‐Tubino et al., ; Dantas et al., ). On the north coast, A. quadriscutis is very abundant in the inner portion of the continental shelf (Le Bail, Keith, & Planquette, ; Le Bail et al., ; Mendes & Barthem, ), but rare or absent in the mangroves of the local tidal creeks and estuaries (Marceniuk, Caires, Rotundo, Alcantara, & Wosiacki, ; Marceniuk, Siccha‐Ramirez, Barthem, & Wosiacki, ). This may be related to the influence of Amazon plume and the low salinity of the internal platform.…”
