The Sperm Whale (Physeter macrocephalus or Physeter catodon) is the largest of all toothed whales and largest living toothed animal.The whale was named after the milky-white waxy substance, spermaceti, found in its head and originally mistaken for sperm or semen.由此可见,它脑袋里的东西是白白的粘乎乎的,被人误认为是sperm ,所以。。。。我想吐,让我去吐一会 ···
