A young hammerhead's 10.5-month journey through the Gulf of California reveals that the endangered shark often swam outside of protected areas, according to a new research that suggests key areas where protection could help the species survive.

After hitching rides from local fishermen, researchers caught and tagged three young scalloped hammerhead sharks (Sphyrna lewini) in the Gulf of California, which separates the Baja California peninsula from mainland Mexico.

Maps of the sharks' wanderings could help conservationists develop plans to protect the vulnerable species.

US lists four species of hammerhead shark under its Endangered Species Act

The US National Marine Fisheries Service has recently listed four populations of scalloped hammerhead shark, Sphyrna lewini, under the American Endangered Species Act (ESA), because of severe threats posed by human exploitation.

“It’s sobering that we must begin adding shark species to the endangered species list,” said Taylor Jones, endangered species advocate for WildEarth Guardians, an American non-profit organisation.

“Our oceans are in serious trouble and this is only the first step toward protecting and restoring the ocean ecosystems that these amazing carnivores call home.”

Shark species worldwide are dwindling in the face of heavy fishing pressures, with animals killed for their meat and fins.
