Human impact on the oceans predates scientific observation, which for many animal populations has captured only recent changes. Such a limited knowledge can hamper finding optimal management and conservation strategies including setting appropriate recovery targets. Sawfishes are among the most endangered marine vertebrates in the ocean. Historical human impacts have resulted in sawfish extinction in many coastal areas around the world; however, in the Mediterranean Sea, their past presence and possible extinction have been debated for decades. Recently, it was concluded that the region never hosted resident populations because of unsuitable environmental conditions. Through an extensive bibliographic and archival search and an extinction analysis, we reconstructed the history of sawfishes in the Mediterranean Sea. Between 1576 and 1959, there were 48 independent accounts of the occurrence of two sawfish species (Pristis pristis, Pristidae and Pristis pectinata, Pristidae), including 24 documented catches. Sawfishes were mainly recorded in the western Mediterranean, in areas close to large rivers with light human impact. Most of the documented individuals were juveniles, suggesting local parturition. Extinction analyses yielded variable results and were affected by the sparseness of records but suggested that both species went extinct in the Mediterranean Sea in the 1960s–1970s. Our results challenge current assumptions on sawfish ecology and biogeography, offer new options for sawfish conservation in the Atlantic and highlight the importance of historical analyses for reconstructing ecosystem baselines and setting recovery targets.

Sawfishes are the most endangered cartilaginous fishes on the planet. Their external morphology facilitates entanglement in fishing nets and their K-selected life history hinders the recovery of exploited populations. The Eastern Amazon coast (EAC) is known to be an area where sawfishes occur in Brazil, but few studies have been conducted in the area to better understand their biology and ecology. The present study reports sawfish captures along the coast of Brazil's second largest state. Data were collected from interviews with fishermen, a literature review, and media reports. In total, 23 captures were recorded between 1984 and 2016. Records include adults, a pregnant female with near-term embryos, juveniles, and young-of-the-year specimens. Most catches were reported in the Canal do Navio, an area under strong human pressure. Sawfish saws are valuable items and, for many anglers in precarious economic and social situations, high market prices eclipse the fishing prohibitions laid down under federal laws. Urgent research is required to understand sawfishes' life history, identify their critical habitats, and effectively manage and conserve these species along the EAC.

An annotated checklist of the chondrichthyan fishes (sharks, batoids and chimaeras) of the world is presented. As of 7 November 2015, the number of species totals 1188, comprising 16 orders, 61 families and 199 genera. The checklist includes nine orders, 34 families, 105 genera and 509 species of sharks; six orders, 24 families, 88 genera and 630 species of batoids (skates and rays); one order, three families, six genera and 49 species of holocephalans (chimaeras). The most speciose shark orders are the Carcharhiniformes with 284 species, followed by the Squaliformes with 119. The most species-rich batoid orders are the Rajiformes with 285 species and the Myliobatiformes with 210. This checklist represents the first global checklist of chondrichthyans to include information on maximum size, geographic and depth distributions, as well as comments on taxonomically problematic species and recent and regularly overlooked synonymizations. Furthermore, a detailed analysis of the biogeographical diversity of the species across 10 major areas of occurrence is given, including updated figures for previously published hotspots of chondrichthyan biodiversity, providing the detailed numbers of chondrichthyan species per major area, and revealing centres of distribution for several taxa.
