In most cases, malaria is transmitted through the bites of female Anopheles mosquitoes. There are more than 400 different species of Anopheles mosquito; around 30 are malaria vectors of major importance. All of the important vector species bite between dusk and dawn.
When replayed at normal speed, time appears to be moving more slowly. A term for creating slow motion film is overcranking which refers to hand cranking an early camera at a faster rate than normal (i.e. faster than 24 frames per second).
The process of limited animation aims to reduce the overall number of drawings. Film is projected at 24 frames per second. For movements in normal speed, most animation in general is done on twos, meaning each drawing is displayed twice, for a total of 12 drawings per 24 frames per second.
