“…Contrasting to species that are relatively abundant in fishery captures ( e.g ., Hypanus guttatus and H. americanus ), S. schmardae was not recorded in several studies conducted in the area between the previous southernmost confirmed records (Pará State) and the one reported in the present study (easternmost Ceará State; see Figure 1). This area comprises estuaries, other sandy or muddy bottoms, and reef environments located on the coastlines of the Brazilian States of Pará (Barthem, 1985; Camargo & Isaac, 2001; Freitas et al ., 2019b; Pinheiro & Frédou, 2004; Rodrigues‐Filho et al ., 2020; Santo et al ., 2005; Silva et al ., 2016), Maranhão (Almeida et al ., 2011; Aragão et al ., 2019; Guimarães‐Costa et al ., 2019; Lessa, 1986; Martins‐Juras et al ., 1987; Nunes et al ., 2005, 2011; Rocha & Rosa, 2001; Silva et al ., 2018), Piauí (Aragão et al ., 2019; Guimarães‐Costa et al ., 2019; Mai et al ., 2012; Melo et al ., 2016) and Ceará (Araújo et al ., 2000; Basílio et al ., 2008; Freitas et al ., 2019a; Freitas & Lotufo, 2015). This indicates how uncommon or rare this species is in this region.…”
