World Wide Web electronic publication, version (10/2013). Scientists assume that size and shape of their pectoral fins have the right dimensions to minimize transport cost. Requiem sharks tend to live in more tropical areas, but tend to migrate. Females release a chemical in the ocean in order to let the males know they are ready to mate. Typical mating time for these sharks are around spring to autumn. Requiem sharks are involved in a large proportion of attacks on humans, among the top five species; however, due to the difficulty in identifying individual species, a degree of inaccuracy exists in attack records.

Etymology

The common name requiem shark may be related to the French word for shark, ''requin'', which is itself of disputed etymology. One derivation of the latter is from Latin ''

requiem A Requiem or Requiem Mass, also known as Mass for the dead ( la, Missa pro defunctis) or Mass of the dead ( la, Missa defunctorum), is a Mass of the Catholic Church offered for the repose of the soul or souls of one or more deceased persons, ...

'' ("rest"), which would thereby create a cyclic etymology (''requiem-requin-requiem''), but other sources derive it from the Old French verb ''reschignier'' ("to grimace while baring teeth"). The scientific name Carcharhinidae was first proposed in 1896 by D.S. Jordan and B.W. Evermann as a subfamily of Galeidae (now replaced by "Carcharhinidae"). The term is derived from Greek ''karcharos'' (sharp or jagged); and ''rhine'' (rasp), both elements describe the jagged, rasp-like skin. Rasp-like skin is typical of
