Footnotes. â 1 The majority of extant mammals are nocturnal (45â55% of non-marine species) and many of the remaining species, especially large-bodied ones, are cathemeral [active both day and night]. Diurnality [active only in the day] is present in a few mammalian clades such as primates, but is much less widespread.
