The millipede known as Haraphe haydeniana is a millipede
with a flattened body. It reaches a maximum length of 40 mm and has a shiny black
body with bright yellow patches on the outside portion of most segements. As with
other millipedes, this millipede has two pairs of legs per body segment. Their
movement is fairly slow.
This particular millipede secretes a dark fluid that has an
odor similar to the almond extract used in cooking. Apparently this is a defensive
manuveur. Millipedes also curl up in tight coils when threatened. As with other
millipedes, Haraphe haydeniana is a vegetarian and scavenger. It tends
to live in moist forests.
