The fact that new, modern-day mammal species are discovered on a fairly regular basis should most definitely not be a surprise to the average Tet Zoo reader. These are not all 'cryptic species' distinguishable only on the basis of DNA: many are morphologically distinctive, honest-to-goodness new animals discovered either in the field or in museum collections. And they're not all bats and rodents: new monkeys, lemurs, sloths and hoofed mammals (peccaries, deer and bovids) have been named in recent years.
