This hammerhead shark necklace consists of a pendant made of 925 Sterling Silver with a Rhodium finish and a 925 Sterling Silver chain.

The Scalloped Hammerhead (Sphyrna lewinii) is one of Costa Rica’s most emblematic shark species, as it occurs in large schools around Cocos Island, making this oceanic island a famous diving spot and generating millions of dollars in Eco-Tourism. The Scalloped Hammerhead is harmless to humans, as it mainly feeds on small fish, squids, and octopuses with their proportionally small mouth. Their hammer-shaped head allows for a 360-degree vision, being able to see above and below at all times, and increases its ability to perceive electromagnetic signals of potential prey.

The hammerhead shark has been history overexploited in the fishing industry, mainly to satisfy East Asia’s demand for shark fins; a prestigious dish offered as a status sign by the High Society. Because of the international trade of hammerhead’s fins, the species is currently listed as Endangered and this status led to nation-wide restrictions in the export of shark fins, including in Costa Rica, which figures as one of the main shark fin exporters worldwide.

Using technologies such as acoustic telemetry, researcher have found that hammerheads often travel vast distances between islands of the Eastern Pacific, connecting Cocos, Galapagos, and Malpelo island and therein creating oceanic highways that require protection. However, pregnant females will always return to the shores in search of mangroves or estuaries, such as the Santa Elena Gulf, to give birth to their life offspring, which too often end up in the nets of artisan fisheries.

Because shark meat is poor in quality but good in appearance, shark meat of juvenile hammerheads is commonly used in street foods, such as “ceviche”. Therefore, it is important for consumers to recognize their part in the conservation of this emblematic species.
