Species	mahi

Big Turtle (Mahi) is a large chelonian commonly referred to by the vernacular name Mahi in multiple coastal cultures. It is recognized in regional inventories, museum catalogs, and ethnozoological accounts and features in legal frameworks, conservation plans, and exhibition programs. Historical records, taxonomic treatments, and indigenous oral histories have all contributed to its contemporary identity and management.

Taxonomy and Nomenclature

The taxonomic placement of Big Turtle (Mahi) has appeared in inventories curated by institutions such as the Natural History Museum, London, Smithsonian Institution, American Museum of Natural History, Royal Ontario Museum, and Muséum national d'Histoire naturelle alongside checklists used by the International Union for Conservation of Nature and regional lists maintained by the Australian Museum, South African National Biodiversity Institute, and Canadian Biodiversity Information Facility. Nomenclatural treatments reference historical figures in systematics such as Carl Linnaeus, Georges Cuvier, Charles Darwin, Alfred Russel Wallace, and later herpetologists affiliated with Harvard University, University of Oxford, Yale University, Columbia University, and University of California, Berkeley. Lexical forms for Mahi appear in ethnographic records collected by scholars at British Museum, Peabody Museum, Field Museum, and by researchers associated with the Royal Society and National Geographic Society. International codes used to stabilize the name include conventions from the International Commission on Zoological Nomenclature and monographs published in outlets such as Journal of Herpetology, Copeia, Systematic Biology, Zootaxa, and Proceedings of the Royal Society B.

Description and Physical Characteristics

Morphological descriptions in comparative studies cite shell dimensions, scute patterning, and limb morphology recorded by teams at University of Cambridge, Princeton University, University of Tokyo, University of São Paulo, and University of Cape Town. Diagnostic characters are outlined in keys published by American Society of Ichthyologists and Herpetologists and regional faunal accounts from the European Union and ASEAN biodiversity initiatives, and illustrated in plates used by curators at Victoria and Albert Museum and Metropolitan Museum of Art for natural history displays. Comparative anatomy work referencing the collections of Smithsonian Institution and Natural History Museum, London often cites skeletal measurements used by researchers from Max Planck Society, CNRS, Smith College, and University College London. Studies in developmental morphology link observed phenotypes to experimental results published by laboratories at Massachusetts Institute of Technology, Scripps Institution of Oceanography, Johns Hopkins University, and Cold Spring Harbor Laboratory.

Distribution and Habitat

Geographic range assessments have been integrated into atlases produced by United Nations Environment Programme, Convention on Biological Diversity, World Wildlife Fund, and regional agencies such as NOAA and Environment Canada. Field surveys reported by teams from Monash University, University of Auckland, Universidad Nacional Autónoma de México, and University of Ghana document occurrences in coastal lagoons, estuaries, and nearshore reefs often inventoried in collaboration with IUCN Red List assessments and the Ramsar Convention database. Habitat descriptions appear in environmental impact statements prepared for projects reviewed by authorities such as European Commission, U.S. Fish and Wildlife Service, Australian Government Department of Agriculture, Water and the Environment, and transboundary management bodies like NATO-funded research consortia and regional fisheries organizations including Indian Ocean Tuna Commission.

Behavior and Ecology

Behavioral ecology studies produced by researchers affiliated with Duke University, Princeton University, University of Florida, Cornell University, and University of British Columbia examine movement patterns, foraging strategies, and social interactions. Trophic relationships are characterized in ecosystem models used by Intergovernmental Panel on Climate Change-linked studies and integrated assessments published in Nature, Science, PNAS, and Ecology Letters. Parasite and disease associations are documented in surveys conducted by laboratories at Centers for Disease Control and Prevention, World Health Organization, Liverpool School of Tropical Medicine, and veterinary units at Royal Veterinary College. Reproductive ecology appears in theses and articles from University of Oxford, Cambridge University Press, and regional journals such as Journal of Tropical Ecology and Marine Biology.

Human Interactions and Cultural Significance

Ethnozoological records preserved by Smithsonian Institution, British Library, Bibliothèque nationale de France, National Museum of Anthropology (Mexico), and indigenous cultural centers document ritual use, iconography, and material culture connected to Mahi in traditions curated by the United Nations Educational, Scientific and Cultural Organization and by anthropologists associated with University of Chicago, University of Michigan, Australian National University, and University of Hawaiʻi. Museums and exhibitions at institutions such as the Louvre, British Museum, Metropolitan Museum of Art, and National Museum of China have featured artifacts and interpretive panels that contextualize human–turtle relationships alongside works by scholars publishing in American Anthropologist, Journal of Anthropological Archaeology, and Ethnohistory. Legal frameworks affecting use and trade have been debated in venues like the World Trade Organization, CITES Secretariat, national legislatures, and environmental tribunals connected to International Court of Justice-advisory opinions.

Conservation Status and Threats

Conservation status evaluations are undertaken in processes coordinated by the IUCN, national agencies including NOAA Fisheries, Environment Canada, Department of Environment, Food and Rural Affairs (UK), and regional programs supported by UNEP and World Bank grants. Threat analyses appear in reports by WWF, Conservation International, The Nature Conservancy, BirdLife International, and academic groups at Oxford University and Yale School of the Environment addressing bycatch, habitat loss, pollution, and climate-driven shifts documented in journals such as Conservation Biology, Global Change Biology, and Ambio. Management actions described in policy briefs and action plans involve stakeholders including local NGOs, indigenous organizations, port authorities, and intergovernmental bodies such as Asian Development Bank and Inter-American Development Bank.
