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.
Gynecologists from the USA have separated this concept into 4 stages: 1  early term 37-39 weeks of pregnancy; 2  completely full-term 39-41 weeks of pregnancy; 3  late-full-term 41-42 weeks of pregnancy; 4  postterm pregnancy more than 42 weeks. So, after the 37th week of pregnancy, the child is considered full-term and ready to the birth. Of course, he will be not as large as children who are born on 41th week of pregnancy, but all childâs organs are already created and capable to be full-functional.
