Mean width: at the proximal vagina: 3.3 cm (1.3 in); at the pelvic diaphragm: 2.7 cm (1.1 in); at the introitus: 2.6 cm (1.0 in) A 2006 U.S. study of vagina sizes using Magnetic Resonance Imaging (MRI) on 28 volunteers between 18 and 39 years old, with heights ranging from 1.5 to 1.7 metres (4 ft 11 in to 5 ft 7 in), and weights between 49.9 ...
Elephant seals or sea elephants are very large, oceangoing earless seals in the genus Mirounga. Both species, the northern elephant seal ( M. angustirostris) and the southern elephant seal ( M. leonina ), were hunted to the brink of extinction for oil by the end of the 19th century, but their numbers have since recovered.
The giant anteater has a low body temperature for a mammal, about 33 °C (91 °F), a few degrees lower than a typical mammalian temperature of 36 to 38 °C (97 to 100 °F). Xenarthrans in general tend to have lower metabolic rates than most other mammals, a trend thought to correlate with their dietary specializations and low mobility.
Microchip implant (human) A human microchip implant is any electronic device implanted subcutaneously (subdermally) usually via an injection. Examples include an identifying integrated circuit RFID device encased in silicate glass which is implanted in the body of a human being. This type of subdermal implant usually contains a unique ID number ...

The function of sneezing is to expel irritants from the nasal cavity. A sneeze (also known as sternutation) is a semi-autonomous, convulsive expulsion of air from the lungs through the nose and mouth, usually caused by foreign particles irritating the nasal mucosa. A sneeze expels air forcibly from the mouth and nose in an explosive, spasmodic ...
Human rhinoviruses preferentially grow at 33 °C (91.4 °F), notably colder than the average human body temperature of 37 °C (98.6 °F), hence the virus's tendency to infect the upper respiratory tract, where respiratory airflow is in continual contact with the (colder) extrasomatic environment.
Botfly. Botflies, also known as warble flies, heel flies, and gadflies, are a family of flies known as the Oestridae. Their larvae are internal parasites of mammals, some species growing in the host's flesh and others within the gut. Dermatobia hominis is the only species of botfly known to parasitize humans routinely, though other species of ...
