A Barrier Reef. The barrier reefs grow parallel to the shore of an island and are separated from it by a deep lagoon.
An encircling coral reef or sandbar can create a shallower area of water near an island, called a lagoon.

A body of water that is encircled by a coral reef is called a lagoon. A lagoon is usually shallow and is separated from the ocean by coral reefs, barrier islands, or sandbars.
Barrier reefs form parallel to the shoreline but are separated by a lagoon.

A ring shaped coral reef is called an Atoll.
a lake and some coral?
An atoll is formed first as a reef that fringes a volcanic island. As the island sinks (after the volcanic activity has ceased and the crust has cooled, becoming denser), the reef continues to build upward, eventually ending up as a ring-shaped structure.
Marine biologists and oceanographers typically determine if an island is part of a coral reef by studying its geological features, the types of marine life present, and conducting surveys to assess the presence of coral formations. Satellite imagery and aerial surveys also play a role in identifying coral reefs surrounding islands.
An atoll is a ring-shaped coral island or string of islands that surround a lagoon. Atolls typically form from volcanic islands that sink into the ocean, leaving a coral reef formation around the edge of the submerged island. The lagoon in the center of an atoll is often shallow and can support diverse marine life.
An atoll is a type of island made from a coral reef that encircles a lagoon. It is often the top of an underwater volcano.
