Atoll.
A ring shaped coral island found for from land is called an atoll.
No, true coral is typically found in marine environments, not in freshwater. Coral reefs are formed by colonies of tiny animals called coral polyps that require specific conditions found in saltwater to thrive.
A low-lying island usually formed by a reef is called a "cay" or "key." Cays are typically made of sand or coral debris and are often found in tropical or subtropical regions. They can emerge from the accumulation of materials around a coral reef, and they may be vulnerable to rising sea levels and erosion.
An atoll is a ring-shaped coral reef, island, or chain of islets surrounding a lagoon partially or completely. Atolls are typically found in warm, tropical oceans and seas, often in the Pacific and Indian Oceans.

They were first found on a small island called Michigan's island. :)
amphibians are found in coral reefs they are found in in tiny oxygen holes of coral
An atoll is a ring-shaped coral reef island that encircles a lagoon partially or completely. Atolls are typically found in the Pacific Ocean and are formed from the remnants of volcanic islands that have submerged over time. The circular shape of atolls is a result of coral growth around the rim of a sinking volcanic island.
A coral atoll is a ring-shaped coral reef or island found in warm, tropical oceans. They are formed from the accumulation of coral skeletons on the rims of submerged volcanic islands over thousands of years. Atolls typically enclose a lagoon in their center.
Lump suckers are not found in coral reefs.
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.
