Researchers from Canada’s Simon Fraser University have revealed that sawfish are already presumed extinct in 46 countries.
“At least one specie of sawfish is missing in 18 countries, and two species have disappeared in 28 countries,” the researchers said.
In a recent report by CNN, they are now termed as some of the world’s most threatened marine fish, with three of the five species of sawfish critically endangered.
NatureNews describes sawfish as the ocean’s most valuable creature with its unique long, narrow nose lined with teeth that resembles a hedge-trimmer or chain saw.
Just like it reflects their names, the saws are used for feeding, digging out animals, and killing or maiming other fish. But despite their alarming appearance, the fish are not considered dangerous to humans.
In a study published in the journal Science Advances, researchers warn that complete extinction is possible if overfishing is not curbed, and if threatened habitats where sawfish live are not protected.
The scientists have identified priority countries where there is still a chance of saving the species.
Conservation efforts should be made in Cuba, Tanzania, Colombia, Madagascar, Panama, Brazil, Mexico and Sri Lanka, where protections could save the imperiled species. Countries like the US and Australia, which already have adequate protections and some sawfish, should be considered lifeboat nations.
