Terry Lee Willis was convicted of robbery and first-degree murder and sentenced to concurrent terms of fifteen years and life imprisonment. The trial court retained jurisdiction over twenty-five years of the appellant’s life sentence pursuant to section 947.16(3), Florida Statutes (1981).
We hold that the trial court erred in retaining jurisdiction over the life sentence because a life span is immeasurable. Cordero-Pena v. State, 421 So.2d 661 (Fla. *2843d DCA 1982). We note, however, that since appellant was convicted of a capital felony, he is required to serve no less than twenty-five years before becoming eligible for parole. See § 775.082(1), Fla.Stat. (1981).
We have examined appellant’s other points on appeal and find them to be without merit. Accordingly, we vacate the portion of the sentence for first-degree murder wherein the trial court retained jurisdiction for twenty-five years over the life sentence. Otherwise, we affirm appellant’s judgments and sentences.
BOARDMAN, A.C.J., and LEHAN, J., concur.
