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.
Most premature babies who are born between 32 and 37 weeks do well after birth. If your baby does well after birth, his or her risk of disability is low. Babies most likely to have long-term disability are those who are born before 26 weeks or who are very small, 2.2 lb (1000 g) or less. Long-term problems may include problems with thinking and learning or cerebral palsy.
