Skin diving is any underwater activity done without the use of Scuba gear, using a mask and flippers, and possibly a snorkel.
It includes swimming, spear fishing, free dive Photography, competitive breath-hold free diving and other apnea competitions.
A mixture of helium and oxygen is commercially known as heliox and generally refers to a mixture of 21% O2 (the same as air) and 79% He, although other combinations are available.
The fastest type of diving is high diving, where divers jump from platforms ranging from 20-27m high and reach speeds of up to 96 km/h. This extreme sport requires precise technique and skills to execute dives safely from such heights.
To dive feet first, jump or step off the diving board with your arms extended above your head. Keep your body straight as you enter the water and aim to make minimal splash. Practice diving from a low height before trying it from a higher diving board.

Yes, the gannet is one of the fastest diving seabirds, reaching speeds of up to 60 miles per hour as it plunges into the water to catch fish.
Free diving is diving without scuba. Skin diving means diving without a wetsuit or scuba. Since you can free dive without a wetsuit they can be the same thing but they are not necessarily always the same thing.
