Movement and distribution of young bull sharks Carcharhinus leucas
in a variable estuarine environment.
They showed rarely found species were Rhizoprionodon oligolinx, Carcharhinus leucas
and Carcharhinus sorrah though Chiloscyllium indicum, Carcharhinus leucas
, Carcharhinus melanopterus, Carcharhinus sorrah were rare in the present study and Rhizoprionodon oligolinx was totally uncommon  stated that the least common species in the catch gives cause for some concern and requires investigation on their population status.

Untold numbers of giant bull sharks (Carcharhinus leucas
)--known locally as Nicaragua sharks--once inhabited the lake and were apparently worshipped by Ometepe's indigenous peoples.
Other predatory sharks, including the oceanic whitetip Carcharhinus longimanus, the bull shark Carcharhinus leucas
, and the tiger shark Galeocerdo cuvier, are probably more often the culprit in attacks on humans than the Great White.
Further support for the use of non-mainstem habitats as refuges from predation comes from research that has shown that juvenile bull shark (Carcharhinus leucas
), the primary potential predator of juvenile smalltooth sawfish in most nurseries (Simpfendorfer et ah, 2005), are more common in the deeper, open-water portions of the Caloosahatchee River (Heupel et ah, 2010), which smalltooth sawfish have been observed to often avoid during the day.

Por otro lado, un estudio llevado a cabo en tiburones de la especie Carcharhinus leucas
que habitan las lagunas costeras del Golfo de California reportan concentraciones de Hg en el higado por debajo de los limites permisibles (Ruelasinzunza & Paez-Osuna 2005).
With the exception of the 3 species of sharks considered potentially dangerous to humans--the tiger shark (Galeocerdo cuvier), the bull shark (Carcharhinus leucas
) and the blacktip shark (Carcharhinus limbatus)--all species caught alive at haulback of the fishing gear were released back to sea.
