The anananggal are self-segmenting aswang in the Eastern Visayan folklore of the Philippines. Unlike their cousins, the manananggal of Luzon, anananggal are wingless like the Indonesian penanggal, and can render themselves invisible – an ability which gives them freedom to enter any house unnoticed.
Aside from preying on pregnant women and attacking children or those who wander at night and the wee hours, anananggal also have a knack for sniffing a corpse in a wake.
To them the smell of a corpse is so irresistible that they would enter a house where there is a wake for the dead and sniff the corpse until they are forced to leave by the approaching dawn. Contact with citrus fruits prevent them from flying. An anananggal will die should sunlight shine upon it while in its segmented form, or if salt, spices, and ash are placed on the stump of its discarded lower half.
