“…Carcharhinus leucas is the species that forms a sizable population in Lake Nicaragua and its drainage into the Caribbean Sea, the Rio San Juan. Contrary to an earlier and still common popular belief, they do not constitute a separate, land-locked species but are identical with the bull sharks of the Atlantic and are able to move freely back and forth between the Caribbean Sea and Lake Nicaragua (Thorson, Watson, and Cowan 1966;Thorson 1971). They are also known to remain in both fresh and salt water for extended periods (unpublished data).…”

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.

“…These include several species of stingrays commonly found in FW tributaries and upstream of coastal areas, including Dasyatis guttata, Dasyatis garouaensis, Dasyatis bennetti and Dasyatis sephen (Thorson et al, 1983;Thorson and Watson, 1975;Taniuchi, 1979). Larger elasmobranchs, such as the bull shark (C. leucas) and the largetooth sawfish (Pristis perotteti) also frequent FW systems but they continue to utilize the marine environment for some critical life stages (Springer, 1963;Thorson et al, 1966;Bass et al, 1973;Thorson, 1974;Thorson, 1976;Jensen, 1976;Taniuchi, 1979;Snelson et al, 1984).…”
