An
ozopore is the opening of a defensive
gland present in some arthropods, notably in
millipedes of the order
Polydesmida and in
harvestmen, the eight-legged arachnids also known as "daddy long-legs". The glands themselves are known as
ozadenes, also called "scent glands", "repugnatorial glands", "odoriferous glands" or "stink glands" by various authors. The name is derived from
Ancient Greek ozo "smell" and
Latin porus "pore, small opening".
