a type of scuba diving where the diver explores sunken ships and other underwater structures

"Wreck diving explores sunken ships."

"Wreck diving explores sunken ships and divers penetrate the hulls to see historical artifacts."

a condition where sudden pressure changes cause nitrogen bubbles in the body, leading to symptoms like joint pain and fatigue

"Divers get decompression sickness."

"Decompression sickness can occur in divers who ascend too rapidly from deep underwater dives, causing severe pain."

the organisms that inhabit the oceans and other saltwater environments

to swim under water with a hollow tube called snorkel through which one can breathe
