The Solomon Islands skink (Corucia zebrata) is an arboreal species of skink that originates from the Solomon Islands. The skink has a long, slender body and strong, short legs. The tail of the Monkey-tailed skink is prehensile and is the basis for the common name of the skink. It is the tail that helps them to maneuver from branch to branch with ease.
