Patella aspera Patella aspera Patella aspera is a species of limpet, a type of sea snail in the family Patellidae. Long considered to be a subspecies of "Patella ulyssiponensis", genetic evidence supports its recognition as a separate species. It is native to Macaronesia. It is known by the common name Azorean limpet, and its local name is "lapa brava". This species lives on rocks in the shallow sublittoral and intertidal zones. It is a keystone species which is of ecological importance as a grazer. It is collected for food. Overharvest is the main threat to the species, which has faced population declines
Human body temperature change according to activities and external factors. In addition to varying throughout the day, normal body temperature may also differ as much as from one day to the next, so that the highest or lowest temperatures on one day will not always exactly match the highest or lowest temperatures on the next day. Normal human body temperature varies slightly from person to person and by the time of day. Consequently, each type of measurement has a range of normal temperatures. The range for normal human body temperatures, taken orally, is (). This means that any oral temperature between is likely
