The pupae are orange-yellow with black chaetae. These worms are characterised by having internal supporting chaetae in their parapodia. Paeonians also, founded the town Chaetae in Tsaousitsa, near Pontoiraklia. The plural form is chaetae or chetae. The abdominal segments are similar, but with the position of the capillaries and chaetae reversed. Close behind the mouth are two hooked chaetae and one or two nephridial pores. The usually eight thoracic segments bear capillaries dorsally and hooked chaetae (bristles) ventrally. The thoracic region of the body consists of seven chaetigers (segments bearing chaetae). The notopodia and neuropodia consist of unbranched capillary chaetae, sometimes with hooks. In annelids, parapodia are paired, un-jointed lateral outgrowths that bear the chaetae. Alongside the notopodia are pairs of neuropodia, each with around 2 to 4 chaetae. Polychaetes, literally meaning "many bristles" are named for their chaetae. The chaetae are unbranched capillaries, spines and hooks. Types of chaetae include capillary, compound, pseudocompound, hooked, and others. Bundles of bristles, called chaetae, project from the parapodia.
