Nurse sharks have not previously been known to migrate. Nurse sharks of the Dry Tortugas (DRTO) mating population have a highly predictable periodic residency cycle, returning to the Dry Tortugas Courtship and Mating Ground (DTCMG) annually (males) or bi- to triennially (females) during the June/July mating season. For 23 years we have followed the movements of 76 recaptured adults of a total of 115 tagged adults. Telemetry detections of 40 females tagged with acoustic transmitters show that… 
Residency and movement patterns of adult Port Jackson sharks (Heterodontus portusjacksoni) at a breeding aggregation site.
Investigation of the residency and movement patterns of Port Jackson sharks Heterodontus portusjacksoni at a breeding aggregation site in Jervis Bay, south-eastern Australia using passive acoustic telemetry found strong preferences for particular reefs within and between breeding seasons, suggesting that males may be engaging in territorial behaviour.
Examining movement patterns of yellowtail snapper, Ocyurus chrysurus, in the Dry Tortugas, Florida
Yellowtail snapper, Ocyurus chrysurus (Bloch, 1970), is an important fisheries species in the Florida Keys. In 2008–2009, yellowtail snapper were tagged with acoustic transmitters and tracked through
Nation-wide assessment of the distribution and population size of the data-deficient nurse shark (Ginglymostoma cirratum)
The study presents the first national assessment of a nurse shark population in Belize, conducted using a combination of transect surveys and baited remote underwater videos (BRUVs), offering a baseline for the long-term monitoring of the Belizean nurse sharks population and improves the understanding of nurse shark abundance and distribution in the wider Caribbean basin.

Physiological markers suggest energetic and nutritional adjustments in male sharks linked to reproduction.
The findings suggest that nurse and blacktip sharks differ in their energetic strategy to support reproduction, however, they likely rely on physiologically important fatty acids during mating, to support spermatogenesis.

Biology and ecology of sawfishes: global status of research and future outlook
The outlook for sawfishes is optimistic if the authors build on 5 successful research and conservation approaches developed over the past 2 decades: local ecological knowledge, identification of nurseries, state-of-the-art techniques, tagging studies, and threat mitigation.
Variation of body condition and plasma energy substrates with life stage, sex, and season in wild-sampled nurse sharks Ginglymostoma cirratum.
This study provides a baseline assessment of body condition and internal physiological state for a data-poor marine species and demonstrates significant ontogenetic, sexual, and seasonal variation in G. cirratum energetic state.

The nurse shark is an opportunistic predator that consumes a wide range of small fishes, primarily grunts (Haemulidae), and a female produces a brood every two years.
Movement and activity patterns of the nurse shark, Ginglymostoma cirratum, in an oceanic Marine Protected Area of the South-western Atlantic
The movement and activity patterns of the nurse shark, Ginglymostoma cirratum, a vulnerable species off Brazil, were investigated using mark-recapture and acoustic telemetry at an oceanic insular
Population genetics of the nurse shark (Ginglymostoma cirratum) in the western Atlantic
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.

Evidence of Partial Migration in a Large Coastal Predator: Opportunistic Foraging and Reproduction as Key Drivers?
The findings suggest that adult bull sharks appear to be highly dependent on coral reef resources and provide evidence of partial migration, where only a portion of the female population undertook seasonal migrations potentially to give birth.
