Because of the great variety of these habitats, the senses of these different species have consequently evolved quite differently, exhibiting a great diversity, with many senses not yet understood or even identified. There are thus still many mysteries regarding the behaviour of aquatic creatures. For example, how do eels find their way across the Atlantic ocean? Why is it so very difficult to swim up to a fish from behind without being detected? And even bank-side freshwater fishermen, for example, know that the vibrations from footsteps can be detected by fish.

Read moreChecking your camera gear into the hold is often undesirable; baggage handlers are nicknamed ‘throwers’ for a reason; and the last thing you want to happen is your camera gear to arrive damaged, stopping you from shooting.

Read moreAs soon as the submarine was in position, and the frogmen were out, the containers were opened and the SLC drawn out. The frogmen then tested all the functions of the SLC before setting out for the target.
Read moreThe challenge in shooting wrecks is that it often involves shooting at large distances, and that the circumstances are rarely optimal when it comes to current, visibility and depth.
Read moreThe idea of such a weapon arose in World War I, when experiments were carried out using different vessels to carry mines into the Austro-Hungarian naval base in Pola. The weapon was developed during the inter-war years
Read moreThe wrecks, and structures found in the sea are veritable time capsules lying in wait for us to explore and expand our understanding of the past. It is also a comparatively quite shallow sea.
Read moreWe can’t help it. Depth has been an allurement since humans first ventured into the underwater world. In 1943, soon after development of the first modern Aqua Lung, Frederic Dumas dived to 61.5 meters breathing compressed air. In 1947, Cousteau’s team (formed in 1943) made experimental compressed air scuba dives to 90 meters. A decade on, Andrea Doria dives become popular for the few at the cutting edge, in July 1956, Peter Gimbel and Dumas made the first dive to the sunken luxury liner, off the coast of New York.

Read moreIn recent years, a new path has opened up for those who do not want to become an instructor and yet want to develop with his or her diving; that path is technical diving.
Read moreThe ‘sting’, which gives these fishes their common name, is a modified dermal denticle mounted near the base of the tail, about one-third along its total length.
Read moreMimicry is one of several anti-predatory devices found in nature. Specifically it is a situation in which one species called the mimic resembles in colour, form, and/or behaviour another species called the model.
