The Caribbean Sea area belongs to the Caribbean region according to the faunal zonation. The region has a high biodiversity, with many species being endemic. The marine fauna of the region is derived from representatives of the Indian and Pacific Oceans, which entered the Caribbean Sea before the formation of the Isthmus of Panama about 4 million years ago.
