There may be people who like centipedes. I have seen people handling tarantulas and scorpions, but never a centipede handler. I would regard such a person with deep suspicion...Now what sort of man or woman or monster would stroke a centipede on its underbelly "And here is my big good centipede." If such a man exists, I say kill him without more ado. He is a traitor to the human race.
r's are known as arthropod reproductive manipulators!!!
they are known to cause cytoplasmic incompatibility (infected males make females have crappy broods), feminization, parthenogenesis, and male mortality in various species
one species of Rickettsia can be transmitted from infected planthoppers and have pathogenic effects on a FREAKING PLANT causing papaya bunchy top disease! that is so insane i can't quite wrap my brain around it... a disease that affects hoppers AND plants... that's... insane
taxonomy info:
Order Rickettsiales
Families 3: Anaplasmataceae and Rickettsiaceae (both of interest to us) and Holosporaceae (live with protista, not as much interest to us) _________________
