Islands formed by limestone animal skeletons are called atolls. These structures are typically circular or oval shaped with a lagoon in the middle, and they are found in tropical regions with coral reefs. Atolls begin as volcanic islands and gradually sink as coral grows on the surrounding reefs, leaving a ring of limestone behind.
A lagoon's boundary is the edge that separates the lagoon from its surrounding environment, whether it is land or open water. This boundary can be defined by physical features such as sandbars, islands, or rocks, or by man-made structures like jetties or seawalls. The boundary of a lagoon plays a vital role in regulating the exchange of water, nutrients, and organisms between the lagoon and its surroundings.

The Marshall Islands are made up of 34 islands. Specifically, they consist of 29 coral atolls (which encircle a lagoon) and 5 coral islands (without a lagoon).
A body of water enclosed by an atoll is a lagoon.
The shortest river in the Cook Islands is the Papatea River, located on the island of Aitutaki. It measures only about 30 meters in length. Despite its short size, it flows into the lagoon and contributes to the island's unique ecosystem.
