snorkeling is the practice of swimming on or through a body of water while equipped with a dive mask a shaped tube called a snorkle , and usuall fin. In cooler waters, a wetsuit may also be worn. Use of this equipment allows the snorkeler to observe underwater attractions for extended periods of time with relatively little effort.
More dangerous creatures, such as sharks and barracudas, also frequent the sea grass. While snorkeling, be alert of your surroundings. It can be hard to judge depth while under water. Keep in mind that you are snorkeling, not scuba diving. If you do decide to get a closer look at something, make sure you don’t go deeper than it will take to get back to the surface on one breath.
