Ugh those really thick black shiny milipedes in Africa that are like 2 feet long, those bastards scare the living shit ou of me. Anything that has more than four legs/appendages, i'll generally avoid. And i can NEVER stick my hand down the garbage disposal (if a fork or spoon falls in or something) without worrying that it'll turn on by istelf. And i used to have a chronic phobia of sea urchins and climbing down really tall ladders
