WebThe hearing of other species in the division of mammals to which humankind belongs has always been of special interest. The hair cell bundles in a particular section of the ear were found to be abnormal compared with those of other rodents, like mice and gerbils. Males of this species are known to have the longest sperm cells of any organism on Earth?5.8 cm long when uncoiled, over twenty times the entire body length of the male.
