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.
By about 32 weeks your baby is a smaller version of a full term newborn. Babies at this stage have fingernails, toenails and hair, and they weigh roughly 3.5 pounds.This last stretch of third trimester pregnancy will be used for baby's weight gain and the strengthening of internal systems such as the respiratory tract. baby born at 32 weeks has a very good chance of surviving and continuing on in life without long term health problems.
