... At the Conference of Parties to CITES (CoP) any Party or any number of Parties to the Convention can put up for consideration proposals for amendments of Appendices I and II for any (group of) species [5]; in recent decades there has been a move for this to be led by Parties where the species in question does indeed occur or by Parties that are otherwise naturally invested in regulating its trade. The scalloped hammerhead shark is a circumglobal species residing in coastal warm temperate and tropical seas in the Atlantic, Pacific, and Indian Oceans [1,6] and as such it occurs in the waters of 109/184 CITES Parties (as well as two non-CITES Parties), 18 of which are situated in the Global North. to include all remaining species of hammerhead sharks on Appendix II was adopted by consensus. This does not suggest a North-South rift, but more a strong disagreement between certain Parties how best to manage marine species. ...

... Our observations align with Fish & Mowbray [21], who auditioned a captive dusky smoothhound through handling and mechanical prodding but did not detect any biological sounds produced by this species. The smoothhound shark genus Mustelus (family Triakidae) comprises 27 species of small (0.6-1.85 m) mesopredatory sharks, showing a high degree of regional endemicity [28,48,54]. These benthopelagic sharks are abundant worldwide in temperate to tropical coastal habitats from shallow waters to a maximum depth of approximately 1500 m [28,41]. ...

... They characterize a small shark family that is generally quite unknown. The 4 currently known species are: The Atlantic nurse shark (Ginglymostoma cirratum Bonnaterre, 1788), the Tawny nurse shark (Nebrius ferrugineus Lesson, 1831), the Shorttail nurse shark (Pseudoginglymostoma brevicaudatum Günther, 1867) and, as the most recently described species, the Pacific nurse shark (Ginglymostoma unami Del-Moral-Flores et al., 2015) (Ebert et al., 2021). In general, nurse sharks are medium-sized, bottom-dwelling and feed mainly on invertebrates and small fish (Ebert et al., 2021). ...

... Despite its small size and low salinity, the Baltic Sea has become home to several shark species. While the entire Northeastern Atlantic Ocean is home to 75 shark species [1], only 4 are resident in the Baltic Sea: The Spiny dogfish (Squalus acanthias), the School shark (Galeorhinus galeus), the Smallspotted catshark (Scyliorhinus canicula) and the Porbeagle shark (Lamna nasus) [1,2,3]. 18 species can be found in the transitional waters of the Skagerrak and Kattegat, although records often refer to a few individuals [2]. ...

... Galeorhinus teeth are similar to those of Pachygaleus but differ by having a much less convex labial crown base and denticulations that can extend further than one-third up the mesial edge (Cappetta, 2012;Ebersole et al., 2019). A comparison of MSC 50033 to published dentitions of the extant Galeorhinus galeus (Linnaeus, 1758) (i.e., Castro, 2011;Ebert & Dando, 2020) revealed that this tooth was likely derived from a lower posterolateral file based on its having a convex mesial edge, short main cusp, and extended distal heel. Several Paleogene Galeorhinus species have been reported in the literature, including G. cuvieri (Agassiz, 1835c), G. duchaussoisi Adnet & Cappetta, 2008, G. loangoensis Dartevelle & Casier, 1943, G. louisi Adnet & Cappetta, 2008 (Arambourg, 1935), G. muelleri (Jaekel, 1898), G. parvulus Dartevelle &Casier, 1943, G. tenuis Averianov &Udovitshenko, 1993, andG. ...

... In the study area, the increase in the proportion of adult females in the catch could potentially cause rapid population depletion. In fact, over the past decades, several targeted shark fisheries have collapsed as a result of the overexploitation of breeding stocks (Compagno, Dando, & Fowler, 2005). Interestingly, the current fishery operates within a hot spot for elasmobranchs without effective management approaches. ...

... The silky shark, Carcharhinus falciformis (Müller & Henle 1839), is a semi-pelagic species of the family Carcharhinidae, commonly found in tropical and subtropical regions of the Pacific, Indian, and Atlantic Oceans (Garrick 1982;Compagno 1984). It inhabits depths from the surface to at least 500 m, with a greater presence near the edges of continental and insular shelves, as well as over deep-water reefs and in the open sea (Compagno et al. 2005;Bonfil 2008). This species exhibits low reproductive potential, characterised by placental viviparity with litters in the range of 2-14 pups (Bonfil et al. 1993;Alejo-Plata et al. 2016), late sexual maturity (Grant et al. 2018), and a gestation period of up to 12 months For full list of author affiliations and declarations see end of paper (Branstetter 1987;Bonfil et al. 1993;Cadena-Cárdenas 2001). ...
