Endospores and Epulopiscium: Some Epulopiscium-like surgeonfish symbionts form mature endospores at night. These spores possess all of the characteristic protective layers seen in B. subtilis endospores and also contain large amounts of dipicolinic acid.
A fever, or pyrexia, is a rise in internal body temperature to levels that are considered to be above normal. Average body temperature is about 98.6Â°F or 37Â°C, and temperatures above 100.4Â°F or 38Â°C are generally considered to be febrile. Body temperature is determined by the body's thermoregulatory set-point.
