Scientists have finally discovered how owls manage to rotate their heads up to 270 degrees without causing themselves serious physical damage.
A new study has found that a combination of unique bone structure and a highly developed vascular system bestows extra mobility on the predators. Scientists at Johns Hopkins University School of Medicine examined snowy, barred and great horned owls for the research.
Sloths are medium-sized mammals belonging to the (two-toed sloth) and (three-toed sloth), classified into six species. They are part of the order Pilosa and are therefore related to antheaters, which sport a similar set of specialized claws. Extant sloths are arboreal (tree-dwelling) residents of the jungles of Central and South America, and are known for being slow-moving, and hence named “sloths”. Extinct sloth species include a few species of aquatic slothsand many ground sloths, some of which attained the size of elephants.
Sloths make a good habitat for other organisms, and a single sloth may be home to moths, beetles, cockroaches, ciliates, fungi, and algae.
