... This trygonorrhinid batoid has a short cuneiform-shaped snout, which is the main morphological character to differ it from other guitarfishes from the Southwest Atlantic (Last et al., 2016). The only somewhat similar guitarfishes in this region include two rhinobatid species, Pseudobatos horkelii (Müller and Henle, 1841) and P. percellens (Walbaum, 1792), which differ from Z. brevirostris because they have an elongated snout (Bigelow and Schroeder, 1953). The Shortnose Guitarfish is commonly caught as bycatch throughout its geographic range (Costa and Chaves, 2006, Chiaramonte et al., 2011, Colonello et al., 2011, Wosnick et al., 2019. ...

... Playful uses occur in several ways, and the animal may be either alive or dead, captured or released, in whole or in parts. The main playful use involves a stingray species known in South Bahia as the lesser numbfish, Narcine brasiliensis (Olfers, 1831), which produces electrical discharges (Bigelow and Schroeder 1953). This is performed as an initiation fishing ritual. ...

... Pre-mature birth or aborting of small pups can also be influenced by other external stressors, such as capture (Whitney & Crow, 2007). In the northwest Atlantic, length at birth has been reported to range from 45 to 50 cm L T (Bigelow & Schroeder, 1948) to around 70 cm L T (Clark & von Schmidt, 1965;. In the Caribbean, length at birth was established at 60-70 cm L T ( Rivera-L?pez, 1970), while in Africa, estimated birth size was 70 cm L T for G. cuvier off Madagascar (Fourmanior, 1961), and 85 cm L T in South Africa (Wintner & Dudley, 2000). ...

... The first reference to the species after Dollo (1904) was by Bigelow and Schroeder (1965) describing a mature male of 490 mm TL from northeast off the South Shetland Islands at Matthias F. W. Stehmann and Simon Weigmann contributed equally to this work. This article is a contribution to the Topical Collection Systematics and Biodiversity of Indian Ocean Sharks, Rays, and Chimaeras (Chondrichthyes) Communicated by D. Ebert 220-240 m depth, and a female of 258 mm TL from northeast off Clarence Island at 585-595 m depth as Breviraja griseocauda (Norman, 1937); both specimens were captured by USNS "Eltanin." ...

... Their depth ranges from 0 to 200 m, but they live preferably close to the water surface at an average depth of 20 m (Pollerspöck and Straube 2024). According to Bigelow and Schroeder (1948), the teeth of S. zygaena have uniformly fine serration while that of smalleye hammerhead, S. tudes Valenciennes, 1822, have coarser serration. Some teeth of S. zygaena are similar to those of Carcharhinus gibbesii, but the cutting edges are completely smooth (Purdy et al. 2001). ...

... This behaviour may occur more readily in cooler waters associated with the SS and off Newfoundland compared to more temperate waters (Murawski and Finn 1988). Optimal water temperatures for adult Haddock range from 4-7 ˚C, with all life history stages of Haddock typically avoiding waters with temperatures above 10 ˚C (Bigelow andSchroeder 1953, Cargnelli et al. 1999). ...

... Bigelow and Schroeder 3 were pioneers in describing these groups using morphological evidence; they studied specimens from the western Atlantic Ocean and categorized them into acanthias, blainville-fernandinus, and megalops or brevirostriscubensis. Later, these researchers renamed these categories after their most ancient representative, resulting in S. acanthias, S. fernandinus, and S. megalops. 4 Garrick 5 proposed a revised naming system based on similar traits but with certain changes, identifying S. fernandinus (Molina, 1782) as a synonym for S. acanthias, thereby creating the groups: S. acanthias, S. blainville, and S. megalops -cubensis. Cadenat and Blache 6 also identified three species groups, providing an identification key for the S. acanthias, S. blainville, and S. megalops groups. ...

... The smalltooth sawfish (Pristis pectinata) was the third identified batoid of the order Rhinopristiformes from among the analyzed specimens. While once found on both sides of the Atlantic Ocean (e.g., Bigelow and Schroeder, 1953), this species is now restricted to waters surrounding Florida, particularly within the Everglades National Park, and the Bahamas (Carlson et al., 2013;Simpfendorfer and Wiley, 2005;Wiley and Simpfendorfer, 2007). The species is present all year in south Florida coastal waters, and individual animal size tends to correlate with habitat preferences; with small individuals or juveniles observed in shallow coastal habitats, such as mangroves and estuaries, while larger juveniles or adults are observed among deeper or open waters (Waters et al., 2014). ...
