An underwater camera is basically a camera that can be used to take images and videos underwater. It can be used for shooting while swimming, snorkeling, or using remote-controlled underwater vehicles.

Most underwater video camera housings are designed to fit a specific camera and use materials such as plastic and aluminum.

Underwater cameras are also standard in the Olympics and other high-profile swimming events, capturing swimmers from underwater.

Underwater cameras are used to find undiscovered marine life, record underwater voyages, and show the world what the deep ocean is made of.
