Facts

  • Males are larger than females (ref: Stry2001)
  • Does not have a hinged plastron (ref: Wiki)
  • Removes ticks and blood-sucking flies from the bodies of warthogs, Cape buffalo and rhinoceroses (ref: Wiki)
  • Males and females have two small tentacles (of unknown function) beneath the chin, and musk glands beneath the fourth to eighth marginals (ref: Stry2001)

Discussion

  • In view of low somatic maintenance, pseudodata k_J = 0.002 1/d is replaced by pseudodata k = 0.3
