Also called Acari, an order of arachnids
which includes mites and ticks.
The body of an acarine is not segmented or divided into abdomen
and prosoma. Acarine larvae usually have three
pairs of legs; adults have four. The Acarina are extremely abundant animals,
found almost everywhere. In terms of their economic impact they are the
most important arachnid order; many species are parasitic on man or domestic
animals, e.g., Sarcoptes causes scabies and the cattle tick carries
babesiosis (redwater fever).
