What are the capitalization rules for *Crotalus oreganus* in binomial nomenclature?
Answer
The genus *Crotalus* is capitalized, and the specific epithet *oreganus* is lowercase.
Binomial nomenclature, established by Carl Linnaeus, requires a standardized format for scientific naming. For any given species, the first part of the name, which denotes the genus, must always begin with a capital letter. The second part, known as the specific epithet, must always be written entirely in lowercase letters. In the case of *Crotalus oreganus*, this means the genus name *Crotalus* starts with 'C' capitalized, while the specific epithet *oreganus* remains entirely lowercase. This dual-part system serves to uniquely identify the species across the entire animal kingdom, distinguishing it from all others.
