Depends on the country you do them in , but there is generally a certificate for Scuba and another for Small Boat Seamanship.

That is a sort of analogy. It means that you attract people to God's Cause.
Force itself doesn't affect scuba diving. It's more the pressure.The further you go down, the more pressure there is.The more the pressure is, the more it effects the air spaces inside you.As the pressure it is, it compresses the air spaces inside of you, creating what is known as a squeeze. these are painful, and can prove dangerous, if you don't sort them out.To sort them out, you have to eitherHold you nose, and blow against it. (don't let the air come through your mouth!)Swallow and wiggle your jawThe important air spaces are in your ears, which you must equalize, and your lungs, but they equalize naturally when you breathe.
People do not work "at" the Great Barrier Reef, as it is a protected area in the ocean. However, many people work work by conducting tours out into selected areas of the Reef. Some tours are fishing tours; others use glass-bottomed boats to give tourists a clear view of the colours of the reef and the fish; many tours take people out scuba diving and snorkelling in the waters.

it can depend what sort of girl your looking for, and what your hobbies/activites are.
Geckos attract mates by preening, or essentially showing off their bodies.
SCUBA diving doesn't really have any specific dietary requirements that would be any different from any other athletic endeavors. Dehydration is a key concern because it can be a contributing factor in decompression sickness "the Bends". Foods high in Potassium (such as bananas) can help avoid cramps... dont eat to much food that makes you bloat (yeast, for example, can cause bloating in some people)
Diving spiders make a sort of "diving bell" underwater. They live in there, so they need to fill it with air so they will have something to breathe. The spines on their body can trap air, so they rise to the top of the water, do a sort of somersault to throw themselves above the water surface and right back down into the water. When they come back under, they are covered in a bubble of air. They swim down to the diving bell where they shuck off the bubble of air. If there still is not enough air in their diving bell, then they may go back up again for another bubble.

It is not clear whether the dream is about a wet suit used for surfing or scuba diving, or an ordinary suit of clothes that is wet. In the first case, the dream suggests the dreamer needs to "dive" or "go deep," probably into memories or into some sort of research. In the second case, the wet clothing could illustrate the common expression, "he's all wet," meaning, thoroughly mistaken.
