Characterized by their distinctive hammer-shaped head, hammerhead sharks are among the most easily recognizable species in the marine world. The peculiar structure of their head not only gives them an unmistakable appearance but also serves practical functions. Their eyes are situated at the ends of the «head,» providing them with greater panoramic vision and aiding them in the search for prey in their habitat. Furthermore, this unique shape also allows hammerhead sharks to have better detection of the electric signals emitted by their prey, such as fish and rays, making them highly effective hunters.
The Galapagos hammerhead sharks are a prominent presence in these waters and can be found in a variety of environments, from shallow waters to depths of up to 600 feet. While they can be solitary at times, they also gather in large schools in specific locations, such as the Darwin and Wolf islands, especially when the Humboldt Current is stronger. These sites have become gathering points for marine life observers, where they can witness the majesty of these creatures in their natural habitat.
Hammerhead sharks are not only important from an ecological standpoint but also an invaluable attraction for diving and marine life observation enthusiasts. The possibility of coming face to face with these majestic predators in their natural environment is an experience often described as thrilling and transformative. Additionally, these prehistoric creatures arouse the curiosity of scientists and conservationists who seek to better understand their behavior, migration, and their relationship with the surrounding ecosystem.
The Pacific hammerhead shark, Sphyrna lewini, is one of the largest members of the hammerhead shark genus. Adult specimens can reach lengths of 4 to 6 meters (13 to 19 feet) and weigh around 230 to 350 kg. Their distinctive hammer-shaped head is their most distinguishing feature and is believed to offer key adaptive advantages. The eyes located at the ends of the head provide a panoramic field of vision, facilitating the search for prey and the detection of predators.
The coloration of the Pacific hammerhead shark varies based on age and environment. Juveniles tend to be darker and may have spots or stripes on their bodies, which helps them camouflage in their habitat. Adults, on the other hand, have a silvery or olive-gray tone on the upper part of their body and a white tone on the underside.
As one of the larger subspecies of hammerhead sharks, Sphyrna lewini can reach notable lengths. Males tend to be smaller than females, with an average length of around 3.7 meters, while females can exceed 5 meters. As for longevity, these sharks are estimated to live up to 30 years under favorable conditions.
This subspecies of hammerhead sharks is native to the Pacific Ocean, and its distribution range extends from the eastern coast of North America to South America and the Galapagos Islands. It is in the latter where they play a crucial role in the marine ecosystem. Pacific hammerhead sharks prefer tropical and temperate waters and can be found in a variety of habitats, from coastal waters to deeper oceanic zones.
Pacific hammerhead sharks are apex predators in their habitat, occupying the top level of the marine food chain. Their diet primarily consists of fish, including other smaller shark species and rays. These sharks are known for their seasonal migration in search of food and mating conditions. During certain times of the year, they can form large schools, especially in nutrient-rich waters.
