Patella vulgata be currently the strongest biological material, and only comparable to the strongest commercial carbon fibres.” The material was able to withstand 4.9 GPa. This considerable tensile strength of limpet teeth is attributed to a high mineral volume fraction of reinforcing goethite nanofibres. Patella vulgata Patella vulgata, common name the common limpet or common European limpet is an edible species of sea snail with gills, a typical true limpet, a marine gastropod mollusc in the family Patellidae. This species is found in the waters of western Europe. The radula in this species is longer than the shell itself. It contains 1,920
Human body temperature Human body temperature Normal human body temperature, also known as normothermia or euthermia, is the typical temperature range found in humans. The normal human body temperature range is typically stated as . Individual body temperature depends upon the age, exertion, infection, sex, and reproductive status of the subject, the time of day, the place in the body at which the measurement is made, and the subject's state of consciousness (waking, sleeping or sedated), activity level, and emotional state. It is typically maintained within this range by thermoregulation. Taking a person's temperature is an initial part of a full clinical examination.
