Usually the kinds of underwater life will change as you go deeper since most species depend to a great degree on the amount of light available. Deeper still, the colours begin to lose their brilliance, reds have gone, so have the yellows and oranges and green is very faint. Most things now appear to be tinged in blues, purples and greys, this is because water acts as a colour filter and removes the brighter colours, leaving the blues as the only light to illuminate your world. Sometimes in the depths, or even close to the surface, you will find the skeletal remains of wrecks, lost in storms or accidents in the mists of time. Gliding through hatch covers and swimming along promenade decks that once held crowds of people, the occasional souvenir maybe found to take home, that is, as long as you have declared it to the appropriate authorities first.
Scuba diving is a worldwide sport.
Divers enthuse about the underwater world from the cold seas of the Arctic and British Columbia, through to the exciting and teeming life and wrecks of northern European waters and onto the brilliant and colourful spectacles of the Coral Reef. Once you are truly bitten by the diving bug, you are a diver for life. Gear Equipment will be provided by the club or centre where you learn. Most divers purchase their own regulators and weights and, some, even bottles. As bottles are expensive and heavy to transport, most prefer to borrow or hire them.
