AB Ectoparasites  include  arthropods  and  creatures  from  other  phyla  that  infest  the  skin  or  hair  of  animals;  the  host  animals  provide  them  with  sustenance  and  shelter.  The  ectoparasites  may  penetrate  within  or  beneath  the  surface  of  the  host  or  may  attach  by  mouthparts  and  specialized  claws.  These  organisms  may  inflict  direct  mechanical  injury,  consume  blood  or  nutrients,  induce  hypersensitivity  reactions,  inoculate  toxins,  transmit  pathogens,  and  incite  fear  or  disgust.  Humans  are  the  sole  or  obligate  hosts  for  many  kinds  of  ectoparasites  and  serve  as  facultative  or  paratenic  (accidental)  hosts  for  many  others.
