Should taxonomy terms such as Crustacea be capitalized? I think yes, but am unsure.

It depends on which level of taxonomy that term is. For genus and higher, names are capitalized. Species and terms more specific than species (like variety and subspecies) are not capitalized.

Thus, for your example, Crustacea should be capitalized because it is a subphylum.

    @Blessed Geek The taxonomic name of the group of mammals is Mammalia. The former is not capitalized, the latter is. Nov 29, 2012 at 16:55

    Moreover, genus and species (and subspecies, if any) are to be set in italic, but higher taxa should be set in roman.
