What is serranila bank?

Serranilla Bank is a small coral atoll in the Caribbean Sea, which is situated between Jamaica and Nicaragua but is claimed by Colombia, Honduras, and Jamaica. It contains several low-lying and uninhabited islets and rocks, which are mostly used for fishing and scientific research purposes. The bank is a habitat for various marine species, including coral reefs, fish, and sea turtles. It is also an area of geopolitical controversy due to its disputed ownership and potential for oil exploration. The sovereignty of the region has been the subject of several disputes among the surrounding countries, with little progress made towards resolving the issue.
