About this species
Largetooth sawfish (Pristis pristis) is part of the curated SpeciesWatch catalogue and is classified as Critically Endangered. Sawfish are not sharks but rays — close relatives of skates that rest on the seabed. Its recorded population direction is decreasing, so the category needs to be read alongside continuing losses of individuals or local populations.
Habitat, behaviour and ecological role
This profile associates the species with marine, freshwater. These labels summarise environments used during different stages of its life rather than drawing an exact range boundary. Their toothed rostrum is both a weapon and a sense organ: it detects the electric fields of hidden prey, then slashes through fish schools to stun them. Its anatomy and behaviour are responses to those environments, while movement can connect distant places requiring different forms of management.
Why this species is at risk
Some sawfish can reproduce without a mate (parthenogenesis) — a last-resort strategy observed in captivity when populations crash. The catalogue records 3 principal pressures for this profile: Bycatch, Fin trade, Habitat loss. They should not be treated as isolated causes. Habitat change, exploitation, pollution, disease and climate stress can reinforce one another, while the importance of each pressure varies between regions and through time.
Conservation outlook
Protecting and reconnecting habitat is a priority, together with infrastructure planning that keeps feeding, breeding or migration routes functional. Fishery management needs enforceable limits, more selective gear, bycatch reduction and coordinated compliance across jurisdictions. Direct protection needs to combine enforcement with conflict prevention, demand reduction and local benefits that make coexistence viable. Actions need long-term monitoring and revision as evidence changes; a positive intervention in one place does not by itself represent recovery across the species.
