# What is the function of the peristomium?

## Answer

The first section behind the prostomium, called the peristomium (Greek περι- meaning "around" and στομα meaning "mouth"), is regarded by some zoologists as not a true segment, but in some polychaetes the peristomium has chetae and appendages like those of other segments.[3]

The segments develop one at a time from a growth zone just ahead of the pygidium, so that an annelid's youngest segment is just in front of the growth zone while the peristomium is the oldest. This pattern is called teloblastic growth.[3] Some groups of annelids, including all leeches,[10] have fixed maximum numbers of segments, while others add segments throughout their lives.[7]

### What is the function of an earthworms Prostomium?

Prostomium Some species of earthworms have a tongue-like lobe
above the mouth called prostomium. The prostomium is actually a
sensory device. Earthworms do not have a nose, eyes, ears, or hands
to gather sensory information about their environment. Instead,
they depend on their prostomium and sensory receptors in their skin
to "feel" their way through the soil. The peristomium is the first
segment from the mouth.
