Just because it is easier. It's hard to stand up in fins (FLIPPERS) on a rocking boat!!

∙ 12y agoIt's easier to walk in fins backwards. Plus you have a lot of gear strapped to your back, so going backwards ensures you won't hit it on whatever you're jumping off of.

Scuba divers don't get crushed by the weight of water when they are diving due to the principles of fluid pressure and buoyancy. The equipment and techniques used in scuba diving are designed to manage the effects of pressure underwater. Here's how it works: Buoyancy: Divers use a Buoyancy Control Device (BCD) to manage their buoyancy. The BCD allows them to control their position in the water column by adjusting the amount of air in the device. By adding air, they become more buoyant and can ascend; by releasing air, they become less buoyant and can descend. Equalizing Pressure: As divers descend underwater, the pressure increases. The human body is filled with air spaces, such as the ears, sinuses, and lungs. To prevent discomfort or injury, divers equalize the pressure in these air spaces by gently exhaling or using specific techniques. Equalizing prevents the pressure from causing pain or damage. Breathing Gas: Divers breathe compressed air or a specialized gas mixture from their scuba tanks. The pressure of the inhaled air is equal to the surrounding water pressure, maintaining a balance and preventing the diver from feeling "crushed." Wetsuits and Drysuits: Exposure suits, such as wetsuits and drysuits, not only provide thermal insulation but also add buoyancy. Divers compensate for this buoyancy by wearing weights. The combination of the exposure suit and weights helps maintain neutral buoyancy, allowing the diver to hover at a specific depth. Pressure Tolerance: The human body is remarkably adaptable to changes in pressure. As long as pressure changes are gradual and divers follow proper procedures for ascent and descent, the body can tolerate the pressure at various depths. It's important for divers to follow established diving practices, including gradual ascent and descent, proper equalization, and maintaining neutral buoyancy. These practices help prevent barotrauma (pressure-related injuries) and ensure a safe and enjoyable diving experience. Additionally, divers are trained to monitor their depth, time underwater, and gas supply to avoid exceeding safe limits.
Generally no. They need to be quite fit to be able to swim in the water :)
Open Water
Divers fall backwards from a boat because it is often the easiest way to make a deep water entry from a small boat or rib.
Most scuba divers just obtain open water certifications from recreational diver training agencies, such as PADI, NAUI, BSAC or SDI.Only military or commercial divers undertake vocational diving qualifications.
I would call it the Great White Pucker Factor.
The deeper the diver goes, the higher the pressure is.
Because fish have gills and can breathe under water and humans do not
