Acari
Acari
Acari (pronounced: ah-kah-ree) is a taxon of arachnids that includes mites and ticks. The term is derived from the Greek word 'akari', meaning 'mite'.
Etymology
The term 'Acari' is derived from the Greek word 'akari', which translates to 'mite'. This term was first used in scientific literature in the 19th century.
Description
Acari are a diverse group of arachnids, with over 50,000 described species. They are characterized by their small size, typically ranging from 0.1 to 1 mm in length, and their lack of antennae. Acari have a simple body structure, with the body divided into two main parts: the gnathosoma, which includes the mouthparts, and the idiosoma, which includes the rest of the body.
Classification
The Acari are classified into two main suborders: the Acariformes and the Parasitiformes. The Acariformes, also known as the 'true mites', are the most diverse group, with over 32,000 described species. The Parasitiformes, which include the ticks, are less diverse but include some of the most well-known and studied species due to their role as vectors of disease.
