Australia, the great brown land down under, is home to many iconic and often strange-looking creatures, both above and below the water. But few are as unique and visually spectacular as the leafy seadragon!
Like a fashion model up on the catwalk, great hammerhead sharks sashay into one’s field of vision, and, if they were human, you would probably say they have just “made an entrance”. Their strange mallet-like head, robust body girth and tall sickle-shaped dorsal fin make them well-nigh instantly recognisable, and most other sharks in the immediate area spot that too and give them a wide berth.
World War II came to the Australian territory of Papua New Guinea in January 1942 when the Imperial Japanese Army invaded Rabaul in New Britain, followed shortly after by the taking of Kavieng in New Ireland. The invasion turned Papua New Guinea into a major theatre of war in the battle for the Pacific, and there were many brutal encounters between the invading Japanese and the defending Allied forces.
Rising out of the depths, a shape emerges from the shadows, methodically swimming in a wide arc. The outline is unmistakable, as it continues to climb and inch closer at every turn. With one last pass, seemingly in slow motion, I am struck by the sheer enormity of the creature in front of me.
The giant Australian cuttlefish (Sepia apama) is the largest cuttlefish in the world, reaching up to half a metre in total length and weighing in at around 11kg. Solitary animals, they are found all along the coastline of the southern half of Australia—from Central Queensland on the eastern coast, right around the bottom of the continent and up to Ningaloo Reef in Western Australia.
Within a day’s drive from New York City is a wreck junkie heaven, with numerous shipwrecks to explore along the St. Lawrence River on the US-Canadian border, in the area called the Thousand Islands. Larry Cohen and Olga Torrey give a sampling of the wrecks in the region popular with both the American and Canadian diving communities.
A fifty-minute flight southeast from the bustle, cruise ships and tourist-centric Nassau, lies the sleepy island of San Salvador. Twelve miles long and five miles wide, she is the tip of an underwater mountain rising from 5,000 metres below (15,000 feet) surrounded by picture-postcard, crystal-clear, blue seas.
Many people are scared witless by sharks, but I love them. I scuba dive and freedive with them whenever I can.
First described in 1837 by the German naturalist Eduard Rüppell, the great hammerhead shark (Sphyrna mokarran) is the largest of the hammerhead shark family and can reach a length of over 6m (20ft), although some specimens have been seen to be much larger than this. However, with overfishing, the great hammerhead is usually observed to be much smaller than this.
