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.
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.
I felt apprehensive heading out to Tiger Beach where I was supposed to enter open water in the presence of some big, wild apex predators, without any protection other than holding up my camera as a shield in case I was singled out as a snack.
As picture perfect as Malapascua is, in a nation of 7,107 palm tree fringed islands, 2.5km long Malapascua wouldn’t be on anyone’s radar were it not for the thresher sharks that treat the island like a spa. Each morning as the sun peeks over the mountains on distant Cebu, Pelagic threshers rise from the depths to be cleaned by reef fish along a deep ledge known as Monad Shoal.
The fox shark, also called the common thresher shark, lives usually at depths of over 200 meters and it is sighted only rarely. This is the main reason, we don’t know very much about these animals, and there is very little good visual documentation showing thresher sharks up close on camera.
Coral reefs are places of immense natural diversity. They accommodate some of the highest densities of animals on earth and have more species than any other marine habitat. However, the species inhabiting coral reefs are not distributed evenly through the oceans.
On a cold day in February 1944, little would the workers of the Commercial Iron Works in Portland, Oregon, have known of the fate and unlikely resting place of the USS LCI(L) 739—now known to those who visit her as the HTMS Sattakut.
