Day 3: Wolf Island, Shark Cove
“Diver’s Paradise.” “The Golden Grail of Diving.” “One of the best diving sites in the world.”
These phrases, among others, have been used to describe the underwater experience associated with Islands Wolf and Darwin.
Both sites are world renown for dense schools of Scalloped Hammerheads (Sphyrna lewini). As you can see from the photo, these guys pose a minimum threat to humans. They tend to be shy and would often dissipate into the surrounding blue whenever we, a group of noisy bubble-makers, tried to approach.
This apparent abundance can be deceiving – these creatures are listed as endangered and are threatened by shark finning and by becoming entangled in nets meant for other fish. Fortunately, these sharks, among other species of sharks, were recently protected at the CITES conference in Bangkok this past March 2013.
Other members of the shark and ray family filled the site. Schools of Silky Sharks, Galapagos Sharks, huge stingrays, and even fleets of spotted eagle rays crossed our paths. Spotted Eagle Rays (Aerobatus narinari) can be found in the Gulf of Mexico and other tropical seas. Their dark coloring with white spots distinguish them from all other types of rays. Like other rays, they eat mostly crustaceans, shellfish, and other creatures that can be found on the sea bottom. Their strange looking snouts even help them dig in the sand in search of food!
While the undulating bodies of the hammerheads seemed graceful against the ocean blue, and the gentle ‘flying’ of the eagle rays made them appear like flocks of birds, the almost militant march of the silky sharks was both heart-stopping and intimidating. As I lay against a rocky outcrop, I watched as a formation determinedly swam in front of me, less than a meter away. Minimizing my breathing, I hid against a rock waiting for the silkies to venture closer.
