A single stout internal chaeta, called an acicula, may be present in each lobe, which are used to support well-developed parapodia. Notopodia and neuropodia can also bear cirri which are tentacle-like projections of the parapodia.
Acicula (sg.: aciculum) are strong, stout internal chaetae that provide support to parapodia in polychaete annelids. [1] Microscope photograph of a parapodium from a specimen of Arctonoe sp. showing the internal acicula that support the two lobes of the parapodium.
Both lobes of the parapodium, the notopodium and neuropodium can bear chaetae. Chaetae on the notopodium are called notochaetae and those on the neuropodium are called neurochaetae. Thick, internal chaetae that provide support for well-developed notopodia or parapodia are called acicula.
Polychaeta (/ ˌ p ɒ l ɪ ˈ k iː t ə /) is a paraphyletic [1] class of generally marine annelid worms, commonly called bristle worms or polychaetes (/ ˈ p ɒ l ɪ ˌ k iː t s /).Each body segment has a pair of fleshy protrusions called parapodia that bear many bristles, called chaetae, which are made of chitin.
Buskiella is a genus of pelagic polychaete annelids placed either in the family Flotidae or Flabelligeridae.In appearance, they are generally bluish or yellowish, depending on lighting conditions, and live exclusively in very deep water.
Oligochaeta (/ ˌ ɒ l ɪ ɡ ə ˈ k iː t ə,-ɡ oʊ-/) [1] is a subclass of soft-bodied animals in the phylum Annelida, which is made up of many types of aquatic and terrestrial worms, including all of the various earthworms.

The number of posterior compound chaetae declines to a number of 5–6 on the posterior parapodia. Salvatoria koorineclavata shows ventral simple chaetae on the majority of posterior parapodia of some specimens. Its anterior parapodia possess 2 aciculae each, one straight and one acuminate, while simultaneously showing solitary acicula in its ...
