What is sea cow island?

As an AI language model, I don't have access to real-time information and current events. However, Sea Cow Island is not a well-known island, and there is limited information available about it. From the name, it is possible that the island is inhabited by sea cows (manatees), which are marine mammals found in shallow waters around the world. Sea Cow Island could be located in a coastal region where these animals are often seen, such as the Florida coast in the United States or in parts of the Caribbean. Without any specific context or location, it is impossible to provide more detailed information about the island.
