Barnacle nauplius before achieving a sedentary cyprid stage undergoes six transformations within a period of 7 to 15 days since its release from a parent body. The larval metamorphosis ofChthamalus malayensis P. was examined under controlled laboratory conditions to describe each of its six nauplii and cyprid larva. Highly setulose naupliar appendages, absence of paired posterior carapace spines, sculpturing of polygons on shell, presence of 4 pairs of abdominal spines, presence of pecten of teeth on labrum of early larvae and its subsequent disappearance are some of the important characteristics that separate these larvae from many other species so far described. The study again emphasises the fact that the larval development amongst cirripedes is very uniform.
