Potential Invasive Indo‐Pacific Acropora in a Coral Reef of Venezuela: A Contribution to Their Morphological and Molecular Knowledge [PDF]

open access: yesEcol Evol
We report the first record of a non‐native hermatypic coral in Venezuela, exhibiting biological traits characteristic of invasive species. The coral is a member of the genus Acropora (Scleractinia: Acroporidae), native to the Indo‐Pacific. This non‐native petrous coral occurred in a reef of the Morrocoy National Park, in the southern Caribbean.
