Proturan
Proturans (
order Protura) are one of the three
hexapod groups that are not
insects. They are whitish entognathous minute
animals less than 1.5
mm in length. Proturans lack both eyes and antennae. Because they lack antennae they are often seen with their fore-legs held up as tactile organs.
