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.
They say a full-term pregnancy is between 39 weeks and 40 weeks and six days. An âearly termâ or premature baby would be born between 37 weeks and 38 weeks and six days. A late term pregnancy reaches the 41st week and by 42 weeks the baby is âpost termâ or in other words, long overdue.
