The lemon shark was first named and described in 1868 by Felipe Poey. [7] He originally named it Hypoprion brevirostris, but later renamed it Negaprion brevirostris. [7] The lemon shark has also appeared in literature as Negaprion fronto and Carcharias fronto (Jordan and Gilbert, 1882), Carcharias brevirostris (Gunther, 1870), and Carcharhinus brevirostris (Henshall, 1891).
It contains the two extant species of lemon sharks: the lemon shark (N. brevirostris) of the Americas, and the sicklefin lemon shark (N. acutidens) of the Indo-Pacific. Both species are large, slow-moving, bulky sharks inhabiting shallow coastal waters, and can be identified by their short, blunt snouts, two dorsal fins of nearly equal size ...
The sicklefin lemon shark may also be referred to as broadfin shark, Indian lemon shark, Indo-Pacific lemon shark, or simply lemon shark. [ 2 ] Based on microsatellite DNA evidence, the sicklefin lemon shark is thought to have diverged from its sister species N. brevirostris 10–14 million years ago, when the closure of the Tethys Sea ...

Shark fin soup is a status symbol in Asian countries and is erroneously considered healthy and full of nutrients. Scientific research has revealed, however, that high concentrations of BMAA are present in shark fins. [139] Because BMAA is a neurotoxin, consumption of shark fin soup and cartilage pills, therefore, may pose a health risk. [140]
The large pectoral fins are normally carried horizontally, perhaps helping the fish attain the profile of a shark. The first dorsal fin has six to nine independent, short, stout, sharp spines. The family name Rachycentridae, from the Greek words rhachis ("spine") and kentron ("sting"), was inspired by these dorsal spines. The mature cobia has a ...
Negaprion eurybathrodon is an extinct species of lemon shark, which existed globally from the Late Eocene to the Pliocene. [1] It was described by Blake in 1862. [ 2 ]
The name Pterolamiops longimanus has also been used. The species epithet longimanus refers to the size of its pectoral fins (longimanus means "long hands" in Latin). The oceanic whitetip shark is called many things in English: Brown Milbert's sand bar shark, brown shark, shipwreck shark, nigano shark, oceanic white-tipped whaler, and whitetip ...
