No, lampreys do not have sacral vertebrae. They are jawless fish belonging to the class Agnatha and possess a primitive vertebral column made up of cartilaginous structures called arcualia, rather than true vertebrae like those found in more advanced vertebrates. Consequently, they lack the specialized sacral vertebrae that support the pelvic girdle in higher vertebrates.
