Which of the following is a defining characteristic generally shared by arachnids, such as spiders, distinguishing them from insects?
AThey typically have eight legs and two main body segments
BThey typically have six legs and three body segments, just like insects
CThey typically have no legs at all
DThey always have colorful wings
Explanation
Arachnids, a group that includes spiders, scorpions, and mites, among others, are generally characterized by having eight legs and a body typically divided into just two main segments, rather than the three segments and six legs generally found in insects. Unlike many insects, arachnids also typically lack wings and antennae. This combination of distinguishing physical characteristics helps biologists reliably classify a given arthropod as belonging to the arachnid group rather than the separate insect group.
