The stalked barnacle Pollicipes pollicipes (Gmelin, 1789), is a strictly littoral and essentially intertidal pedunculate cirripede that lives by forming dense aggregates or clumps on exposed rocky shores and cliffs associated with a high degree of hydrodynamism (Barnes 1996).
Since some women are unsure of the date of their last menstruation (perhaps due to period irregularities), a baby is considered full term if its birth falls between 37 to 42 weeks of its estimated due date. 1  The unborn baby spends around 37 weeks in the uterus (womb), but the average length of pregnancy, or gestation, is calculated as 40 weeks.
Babies born in certain time frames of pregnancy are categorized in the following ways: â 1 Early termâ is 37 weeks, 0 days to 38 weeks, 6 days. â 2 Full termâ is 39 weeks, 0 days to 40 weeks, 6 days. â 3 Late termâ is 41 weeks, 0 days to 41 weeks, 6 days. â Post termâ is 42 weeks, 0 days or more.
