What is the meaning of Protura?
: a group of very minute primitive wingless blind arthropods that lack antennae, have the mouth parts concealed within the head, undergo no noticeable metamorphosis except an increase in the number of abdominal segments, and are sometimes considered to form an order of Insecta or more often in current classification …
What do Protura eat?
Proturans are small hexapods, closely related to Collembola and insects. They have no antennae or eyes and are found in moist, non-acidic soils. Proturans primarily eat fungal hyphae.
Why are Protura not insects?
Unlike most insects, proturans lack antennae and possess 12 abdominal segments (instead of the typical 11), 3 of which are added postembryonically in successive nymphal molts, or sheddings of skin (anamorphosis). The front legs, carried like antennae, serve a sensory function.
How many legs do protura have?
six legs
Life History & Ecology Proturans are usually regarded as the most primitive of all hexapods. They have six legs and three body regions (head, thorax, and abdomen), but they lack most of the other physical features that are common to arthropods.
What family is protura?
In North America, the Protura are represented by three families: Eosentomidae (8 species) Acerentomidae (9 species) Protentomidae (3 species)
What family is Protura?
What is unique about the Protura compared to all other Hexapods?
The Protura constitute an order of hexapods that were previously regarded as insects, and sometimes treated as a class in their own right. Uniquely among hexapods, proturans show anamorphic development, whereby body segments are added during moults.
What is the function of collophore?
A collophore is a tube-like structure on the ventral side of the first abdominal segment of the body of springtails (collembolans). It used to be believed that it served to stabilise the animal when it jumped by sticking to the surface on which it moved.

What kind of soil does a Protura live in?
Protura are found primarily in leaf litter, rotten logs, soil, and moss in wooded areas but also inhabit agricultural soils, meadows, and turf. Most proturans live close to the soil surface, although some small species can be found as deep as 10 in (25 cm).
How big is the head of a Protura?
Protura are cosmopolitan in distribution and include about 180 named species. Characteristically, proturans are small-bodied (less than 2 mm long) and elongate. The head is prognathous, with entognathous piercing mouthparts and well-developed maxillary and labial palpi.
How many species of Protura are there in the world?
Protura are a class of entognathous Hexapoda (sometimes considered a primitive order of minute Insecta). The name Protura is derived from Greek (protos=first; oura=tail). Protura are cosmopolitan in distribution and include about 180 named species.
What are the physical characteristics of a proturan?
Physical characteristics Proturans are cryptic, pale, and minute wingless hexapods ranging from 0.024 to 0.06 in (0.6–1.5 mm) in length. The head is conical and prognathous, and only the tips of the styliform mouthparts can be seen externally.
