The nurse shark is an extremely abundant shallow water species in Florida and the Caribbean, yet its biology is poorly known. Moreover, there is a great deal of misinformation about it in the literature. The maximum size and weight attained by the nurse shark have often been exaggerated. None of the specimens measured in this study exceeded 265 cm TL and 114.5 kg, and none of the specimens actually measured by other researchers exceeded 280 cm. Females reach maturity at a length of 223–231 cm… 
Habitat use of the nurse shark, Ginglymostoma cirratum, off Recife, Northeast Brazil: a combined survey with longline and acoustic telemetry
TLDR
The combined analysis of longline and telemetry data indicated possible differences in habitat usage between sexes of nurse sharks off Recife, northeastern Brazil.
Population structure of nurse sharks, Ginglymostoma cirratum (Orectolobiformes), caught off Ceará State, Brazil, south-western Equatorial Atlantic
The nurse shark, Ginglymostoma cirratum, is considered an endangered species in Brazil and its capture by fisheries forbidden. Despite such legislation, nurse sharks continue to be caught as these
Defensive strategies of neonate nurse sharks, Ginglymostoma cirratum, in an oceanic archipelago of the Western Central Atlantic
TLDR
Two defensive tactics of neonates of nurse sharks, Ginglymostoma cirratum, are reported based on underwater observations and have important implications for identifying important habitat in nursery areas, and also for the management of this vulnerable species off South America.
Population genetics of the nurse shark (Ginglymostoma cirratum) in the western Atlantic
TLDR
The western Atlantic population of nurse sharks is genetically subdivided with the strongest separation seen between the offshore islands and mainland Brazil, likely due to deep water acting as a barrier to dispersal.
The reproductive biology of the porbeagle shark (Lamna nasus) in the western North Atlantic Ocean
TLDR
Evidence from this study indicated a one-year reproductive cycle and gestation period lasting 8–9 months in porbeagles, which are nourished through oophagy.
Partial migration of the nurse shark, Ginglymostoma cirratum (Bonnaterre), from the Dry Tortugas Islands
TLDR
Some overwintered and some resumed courtship in June, demonstrating both resident and migratory contingents within their population, partial migration and an ability to navigate with high spatial and temporal precision.
Multiple Paternity in the Nurse Shark, Ginglymostoma Cirratum
TLDR
It is demonstrated that at least four fathers must have fathered this brood of sharks consisting of a mother and 32 pups, suggesting a mechanism by which populations of this species may maximize genetic variability.
The reproductive biology and ecology of the Port Jackson shark Heterodontus portusjacksoni in the coastal waters of eastern Australia
The reproductive biology and ecology of the Port Jackson shark Heterodontus portusjacksoni was investigated at three locations on the central and southern coast of New South Wales (NSW), Australia
Gonadal Morphology, Histology, and Endocrinological Characteristics of Immature Female Whale Sharks, Rhincodon typus
TLDR
The present results indicate that even the whale shark over 7 m in TL are still histologically and endocrinologically immature, and will contribute to protection activities and increased success in captive breeding of whale sharks.
Exact Enumeration of Sires in the Polyandrous Nurse Shark (Ginglymostoma cirratum)
TLDR
Exact enumeration of sires can provide valuable information for understanding reproductive ecology of live-bearing vertebrates and may reflect multiple fertilizations over a prolonged period.
