family that includes a family of migratory, live-bearing sharks
of warm seas, sometimes also found in brackish or fresh water, such as the tiger shark
, blue shark
, bull shark
, and milk shark
. The name comes from the French word for shark, requin
Family members have the usual carcharhiniform characteristics. The eyes are round, and the pectoral fins are completely behind the five gill slits. Most species are viviparous, the young being born fully developed.
Many of the species in this family grow to considerable size, the record holder being a tiger shark measuring 7.4 meters.
Requiem sharks are responsible for a large proportion of attacks on humans. However; due to the difficulty in identifying individual species, there is a degree of inaccuracy in attack records.
Carcharhinidae may be a Superfamily, divided into Galeocerdidae, Isogomphodontidae, Rhizoprionodontidae, Scoliodontidae, Scoliodontidae, Triaenodontidae, and Carcharhinidae.
