Whether you’re an experienced or new diver, you probably have a thing or two to learn. There’s always something about this vast underwater world that we can learn. Here are seven facts that many people don’t know about scuba diving? How many of them do you know?
1. You don’t have to be a great swimmer!
If you’ve been staying out of the water because you’re not a strong swimmer, it’s time to put on that wetsuit! When you scuba dive, you don’t actually swim like you would when you’re close to the surface. Yes, it does help to know how to swim, but you don’t have to hold your breath (actually, please don’t) or know any specific stroke to be a great scuba diver.
2. Only 2 species are known to attack unprovoked
Your biggest fear may be sharks, but they are not the most aggressive life forms you will find under water. The clownfish and the trigger fish are most likely to attack if you get too close, especially if they have eggs nearby. Apart from this, avoid touching marine life and you should be fine. Of course, there are exceptions to the rule, but your chances of being attacked are shockingly low.
3. Objects are magnified under water by about 33%
They also appear 25 percent closer than they actually are, so a buddy who encounters a shark may actually feel like it was a scarier experience than it was. Okay, maybe it was still just as scary…
4. Many recommend waiting 24 hours after diving to fly
The recommendation is given to ensure any built-up nitrogen is out of your system before you get on a plane. The science of this is up for debate, but most divers feel it’s better to be safe than sorry.
5. Below 10 meters, you cannot see red or yellow!
You may have thought it was just water reflection, but this is the real reason why everything looks so blue down there. If you cut yourself, your blood will look blue. If you’ve noticed vibrant reds and yellows in scuba photography, it’s because the underwater photographer is using a special light.
6. Jacques Cousteau invented the Aqualung in 1943
Cousteau was an innovator in the world of SCUBA, but people were diving with different types of gear since the 1600s.
7. Children can dive as young as 8 years of age
There is some debate about whether a child of this age is mature enough to dive, but that determination is up to the child’s parents. Any child who is 8 or older and strong enough to handle the gear can try out diving.
