Carcharhinus perezii is the Caribbean reef shark, a medium to large requiem shark found primarily in the western Atlantic and Caribbean Sea. It is widely encountered around coral reef systems and seamounts associated with nations such as Cuba, Bahamas, Venezuela, Brazil, and United States territories. The species is a subject of regional fisheries management, tourism operations, and conservation assessments by organizations including the IUCN and the Convention on International Trade in Endangered Species of Wild Fauna and Flora (CITES) discussion forums.

Taxonomy and Nomenclature

Described by Felipe Poey in 1876, Carcharhinus perezii is placed within the family Carcharhinidae, which also contains genera linked to taxa described by Georges Cuvier and Johann Reinhold Forster. Historical taxonomy has included comparisons to species treated by George Brown Goode and modern revisions by researchers affiliated with institutions such as the Smithsonian Institution and the Field Museum of Natural History. The specific epithet honors early collectors and is preserved in nomenclatural treatments appearing in catalogs like those of the British Museum and the Natural History Museum, London.

Description

Adults typically reach lengths of 2.5–3.0 m, with robust bodies, a short rounded snout, and a broadly triangular first dorsal fin reminiscent of plates illustrated in monographs by authors at the American Museum of Natural History and the Natural History Museum of Los Angeles County. Coloration is gray to brown dorsally, with a white ventral surface; fin tips may be slightly darker, a trait noted in field guides used by researchers from the University of Miami and the University of Florida. Dentition and tooth morphology are diagnostic in taxonomic keys published in journals such as those of the Linnean Society of London and compared across Carcharhinus species in studies supported by the National Oceanic and Atmospheric Administration (NOAA).

Distribution and Habitat

The species occupies coastal and insular shelf zones throughout the western Atlantic, with records from waters surrounding Bermuda, the Greater Antilles, Belize, Trinidad and Tobago, and the northern coast of South America. It frequents coral reef systems, drop-offs, and sandy flats, habitats surveyed by researchers working with the Smithsonian Tropical Research Institute and conservation programs funded by the World Wildlife Fund. Seasonal movements and site fidelity have been investigated in tagging programs coordinated with agencies such as the National Park Service and regional universities in the Caribbean.

Biology and Ecology

Carcharhinus perezii is an apex or mesopredator within reef ecosystems, preying on bony fishes documented in stomach-content studies by teams from the University of Puerto Rico and the Universidad Autónoma de Santo Domingo. It interacts ecologically with rays and teleost assemblages studied in expeditions backed by the Caribbean Fishery Management Council and researchers at the University of the West Indies. Behavioral observations at cleaning stations have been reported in studies affiliated with the Woods Hole Oceanographic Institution and dive operators linked to the Bahamas National Trust.

Reproduction and Life History

Reproduction is viviparous with placental nourishment, a mode discussed in comparative analyses appearing in publications from the American Fisheries Society and the Royal Society. Litter sizes commonly range from 2–6 pups, with gestation periods estimated through tagging and capture data gathered by teams associated with the Gulf and Caribbean Fisheries Institute and the University of South Florida. Age and growth studies using vertebral band counts have been conducted by researchers at the Florida Museum of Natural History and are relevant to stock assessments prepared for regional fisheries management organizations.

Conservation Status and Threats

Listed as Vulnerable by the IUCN Red List assessments, the species faces pressures from directed and incidental capture in gillnets, longlines, and artisanal gear documented in reports by the Food and Agriculture Organization (FAO) and regional fisheries commissions. Habitat degradation from coral bleaching events linked to climate anomalies observed by the Intergovernmental Panel on Climate Change (IPCC) and coastal development projects overseen by governments such as those of Mexico and Panama further threaten populations. International trade considerations and conservation recommendations have been discussed in policy forums involving the Convention on Biological Diversity and national agencies like the Bahamas Department of Marine Resources.

Human Interactions and Fisheries Impact

Caribbean reef sharks are important to ecotourism industries operating in destinations promoted by national tourism boards such as those of Bahamas and Cayman Islands, where provisioning and shark-diving attract divers associated with operators certified by the Professional Association of Dive Instructors. Conversely, the species is targeted for meat, fins, and liver oil by fisheries reported in catch data compiled by the FAO and analyzed by marine scientists at institutions like the University of the West Indies. Management measures, including marine protected areas administered by agencies such as the National Oceanic and Atmospheric Administration and national park authorities, aim to reconcile fishing interests with conservation goals recommended by NGOs including the Pew Charitable Trusts.
