Carcharhinus porosus (Ranzani 1839) View in CoL

Extant specimens: ACL-HN-0045 ( Fig. 6 View FIGURE 6 ).

Classification on the specimen: “A. N. Squalus ”.

Common names on the specimen (Portuguese/Tupi): None.

Comments: This species was undescribed at the time Veloso prepared it. Seven herborized Squalus are mentioned in the inventory of the Ajuda Cabinet ( Ferreira 1794), and three specimens of Squalus zygaena (= Sphyrna zygaena ) were transferred to the Lisbon Academy of Sciences. Since the hammerhead shark Sphyrna is easily recognizable, it is likely that this specimen was not included in the transference document. Although not explicitly referenced in Ichthyologia Fluminesis manuscript, it is possible that it corresponds to the taxon Veloso referred to as Squallus [sic] mustellus [sic] (= Squalus mustelus Linnaeus 1758 = Mustelus mustelus ). Antunes & Balbino (2003) also identified the specimen as Carcharhinus porosus . Carcharhinus porosus inhabits the Western Atlantic region from Louisiana ( USA) to Santa Catarina ( Brazil), and the eastern Pacific from the Gulf of California to Peru ( Ebert et al. 2021). Once a commonly captured species in certain areas of Brazil, its population decline led to its classification as “Critically Endangered” (CR; ICMBIO 2018).
