Morphology
These minute
ommatidia
.
- Collembolans have a ventral tube termed a furcula. The furcula is the "spring" for which the Collembola are given the name springtails.
- Proturans, sometimes referred to as "coneheads", do not have eyes or antennae. They possess a telson and abdominal styli thought to be vestigial legs.
- Diplurans have a pair of caudal cerci, from which their name, meaning "two-tailed", is derived. They also possess abdominal styli.
