Sharks are wild predators and should never be taken lightly, but most pose little to no threat to divers. Instead of being feared, these beautiful animals should be respected.
Q. Which one is bigger Atlantic or Pacific Ocean?
The Atlantic Ocean covers an area of approximately square miles . Covering approximately 20 percent of the Earth’s surface, the Atlantic Ocean is the second largest ocean basin in the world, following only the Pacific. However, it is only slightly larger than half the size of the Pacific Ocean.

Q. Do sharks come at night?
When do the sharks come out to play? Sharks will generally hunt at dawn and dusk and at night, but like many predators will feed at any time they come across prey unless they have just eaten and some female sharks like the female Grey Nurse Sharks do not eat at all during mating season.
Q. Why do divers wear black?
It May Be Better for Regulating Body Temperature Darker colors are especially effective since they absorb more heat and light than brighter colors. Black—which actually isn’t a color, but the absence of color—absorbs the most light, reflects very little, and therefore traps in the most heat for the wearer.
Q. How do freedivers equalize?
The most common equalization technique that Scuba divers and people new to freediving use are the Valsalva maneuver. You simply pinch your nose and create pressure from your diaphragm by trying to exhale through your nostrils against your pinched nose.
Q. Do freedivers wear ear plugs?
You can wear earplugs while freediving but not just any earplugs. Freediving earplugs will be vented in some form. Be sure to equalize while freediving. Wearing earplugs do not take the place of equalization.
Q. At what depth do you need to equalize?
A diver needs to equalize approximately every two to three feet (1 m). Doing so is particularly important in the first 15 to 30 feet (5 to 10 m) of the dive. This is when the largest proportional pressure change takes place. The art of equalizing ear and sinus cavities is to do it early and often.
Q. How do you equalize properly?
Most divers are taught to equalize by pinching their nose and blowing gently. Called the Valsalva Maneuver, it essentially forces the tubes open with air pressure. The better way is to use the throat muscles to pull your eustachian tubes open the way nature intended — by swallowing.
