Updated Distribution Range of Toadfishes (Sanopus Smith 1952, Batrachoididae) in the Southern Gulf of Mexico and Mexican Caribbean Damián A. Cedillo-Reyna 1 & Joshany M. Clarke-Acosta 1 & Alfonso Aguilar-Perera 1 Accepted: 17 November 2020 # Springer Nature Switzerland AG 2020
Abstract Worldwide, toadfishes (Batrachoididae) comprise 83 species belonging to 23 genera. In the western Atlantic, there are seven genera and 23 species, and the genus Sanopus Smith 1952 has six species with limited geographic distribution range in the Gulf of Mexico (GOM) and Caribbean Sea (CS). This work compiled and reviewed information from scientific literature and database revisions on distribution range of Sanopus species, with emphasis in the southern GOM and Mexican CS. Sanopus astrifer, S. reticulatus, and S. splendidus showed updated records from their type locality, while S. barbatus, S. greenfieldorum, and S. johnsoni had no change in distribution. We recommend improving sampling effort for recording Sanopus based on direct underwater visual census and sample collections to expand opportunities to update species distribution range, increase biological data, and provide information to assess conservation status of these species in the region.

Introduction The toadfishes (Batrachoididae) comprise 83 species, belonging to 23 genera, inhabiting marine and estuarine habitats from tropical and subtropical zones (Nelson et al. 2016). There are seven genera (with 23 species) known from the western Atlantic: Amphichthys Swainson, 1839; Batrachoides Lacèpede, 1800; Opsanus Rafinesque, 1818, Porichthys Girard, 1854; Sanopus Smith 1952; Thalassophryne Günther, 1861; Triathalassothia Fowler, 1943 (Collette 2002; Greenfield et al. 2008). In the Gulf of Mexico and Caribbean Sea, Sanopus Smith 1952 has six species with limited geographic distribution range (Collette 2002; Greenfield et al. 2008; McEachran and Fechhelm 2005). In the Gulf of Mexico (GOM), Sanopus reticulatus Collette 1983 was first described from the northern coast of the Yucatan Peninsula, Mexico (Collette 2002, Greenfield et al. 2008, McEachran and Fechhelm 2005) and there is no record in the Caribbean Sea (CS). In the CS, S. splendidus Collette 1974 and S. johnsoni Collette 1974 were first described off
Cozumel, Mexico (Collette 2002; Greenfield et al. 2008), and no records in the GOM yet. S. greenfieldorum Collette 1983 and S. astrifer (Robins and Starck 1965) were first described off the Belize coast (Collette 2002), and no records in the GOM. S. barbatus (Meek and Hildebrand 1928), described off Panama, is a wide-ranging toadfish in the CS from Belize to Panama (Collette 2002, Greenfield et al. 2008), but there is no record in the GOM. An updated geographic distribution range of Sanopus species is necessary because a biological conservation assessment of these species requires more ecological and biological data. However, studying the biological aspects of these species is challenging due to th
