Breeding ground for smooth hammerhead sharks found in Galapagos

A groundbreaking discovery in the waters surrounding Ecuador’s Galapagos archipelago has sparked excitement among marine biologists and conservationists alike. According to a statement issued by the national park, the team has identified a potential breeding ground for the smooth hammerhead shark (Sphyrna zygaena), a find described as “very rare” and potentially revolutionary in our understanding of these elusive creatures.

“The discovery of these new breeding areas is very important, especially for the hammerhead shark,” said Galapagos National Park ranger Eduardo Espinoza. “It is an iconic species of the Galapagos, but it is critically endangered.” Smooth hammerhead sharks, found in the Atlantic, Indian and Pacific oceans, in temperate and tropical waters, are among the nine recognized species of hammerhead sharks. There is limited data on the life history of the species, although it is presumably at least as biologically sensitive as other hammerhead sharks. If its presence is confirmed in the Galapagos, it would mark an important milestone as it would be the first documented breeding site of this species in the region. While these majestic creatures have long captured the fascination of scientists, unfortunately, their population has been declining. The species is classified as “vulnerable” on the International Union for Conservation of Nature’s list of threatened species because its fins are highly valued. Because of this, the species is frequently caught with a variety of gears, including longlines, gillnets, purse seines, and trawls.

The expedition, led by scientists on behalf of Greenpeace, ventured into the Galapagos Marine Reserve, a protected area teeming with life. Several weeks ago, expedition scientists found a young female smooth hammerhead shark near Isabela Island, the largest in the Galapagos archipelago. The team wasted no time in tagging the shark, a crucial step that will allow researchers to track its future movements and confirm whether it does indeed frequent a breeding area. Going forward, continued research and monitoring efforts will be essential to confirm the importance of this discovery and inform conservation strategies aimed at protecting the smooth hammerhead shark in the Galapagos and beyond. For now, scientists are preparing for a sustained effort to gather more data and determine the extent of this potential breeding ground.

Specific nursery locations have been kept confidential to ensure protection of the species. Previously, scientists had identified two other areas with similar characteristics on nearby islands within the Galapagos Marine Reserve. “We managed to include these nurseries on a list of important areas for shark conservation, a new category of protection under the IUCN,” Espinoza said.

Thanks to Charles Darwin’s theory of evolution, the Galapagos Islands occupy a special place in the annals of scientific history. The archipelago’s isolation and unique environmental conditions have given rise to a host of species found nowhere else on Earth, from giant tortoises to flightless cormorants and marine iguanas. This latest discovery, scientists argue, underscores the importance of preserving the Galapagos’ fragile marine environments. As human activities continue to put pressure on marine ecosystems around the world, it is imperative that we take proactive measures to safeguard these vulnerable habitats. Efforts to protect the Galapagos Marine Reserve, one of the largest protected areas in the world, have been underway for decades. Strict regulations govern activities at this UNESCO World Heritage Site, such as fishing and tourism, to minimize human impact on these delicate ecosystems; However, challenges persist, ranging from illegal fishing to the impacts of climate change and pollution.

Education and awareness also play a crucial role in building support for conservation efforts, the team says. As news of this discovery spreads, they hope it will serve as a rallying cry for action. Whether supporting local conservation initiatives, advocating for sustainable fishing practices, or simply spreading the word, scientists believe that every individual can make a difference in preserving the natural wonders of the Galapagos.
