Abstract: Randomly amplified polymorphic DNA (RAPD) analysis was used to assess the genetic variation of the sea cucumber Holothuria polii population. A total of 33 loci were chosen from the 7 primers used. The study revealed that there is divergence between sub-populations found on the east coast and the west coast of Malta, especially at the Anchor Bay site (I = 0.7; D = 0.3). On the other hand, Delimara’s sub-population showed a high homozygozity and less effective alleles (H = 0.214, N = 1.295), possibly due to a decline in numbers, as a result to new selection pressures. The UPGMA dendrogram obtained of the entire Maltese population shows that H. polii is sub-divided into two distinct populations, the north-westerly sub-populations and the south-eastern sub-populations.
