Distribution Species known for European waters. According to Blake & Lavesque (2017: 572) "... only six species of
Chaetozone have been well described and documented from European waters: C. setosa Malmgren, 1867, the type
species; C. carpenteri McIntosh, 1911; C. christiei Chambers, 2000; C. corona; C. gibber, and C. jubata Chambers
& Woodham, 2003. Chaetozone elakata [Blake & Lavesque, 2017 is] the seventh well-documented species in
European waters. Except for C. jubata, which is a deep-water species from depths of 350–1800 m, the other six
European species of Chaetozone all occur in subtidal sediments to depths of no more than 100 m." [details]

Etymology Malmgren p.96 (book version of article, or 206 in journal) gives the derivation from Greek in a footnote. Transcribing the lettering it refers to 'chaite' feminine, meaning hair, and 'zone' feminine, meaning belt, thus a belt of hair, in reference to the posterior girdle of spines characteristic of the genus. [details]

Diagnosis Blake (2015:504) "Prostomium blunt to conical, peristomium elongate to short, usually lacking eye spots, with a pair of small nuchal slits or depressions at posterior edge; with a single pair of grooved dorsal tentacles arising from posterior edge of peristomium, or sometimes more posterior on an achaetous anterior segment, or rarely an anterior setiger. First pair of branchiae arising from an achaetous segment or first setiger; or sometimes with first two pairs of branchiae on a single anterior segment. Body basically thick and fusiform over many segments, rarely with middle or posterior body segments beaded or moniliform. Chaetae include capillaries on most setigers and acicular spines in neuropodia and/or notopodia, spines typically concentrated in posterior segments, forming distinct cinctures with spines emerging from elevated membranes; cinctures with few to many spines and with none to many alternating capillaries; some species with posterior noto- and neuropodial sigmoid acicular spines numerous, encircling entire posterior parapodia; bidentate spines sometimes present in juveniles or occasionally in ventral most position of far posterior setigers of adults accompanying unidentate spines in cinctures; some species with long, natatory-like capillaries, sometimes limited to gravid individuals. Pygidium a simple lobe, disk like, or with long, terminal cirrus [details]

Distribution Species known for European waters. According to Blake & Lavesque (2017: 572) "... only six species of
Chaetozone have been well described and documented from European waters: C. setosa Malmgren, 1867, the type
species; C. carpenteri McIntosh, 1911; C. christiei Chambers, 2000; C. corona; C. gibber, and C. jubata Chambers
& Woodham, 2003. Chaetozone elakata [Blake & Lavesque, 2017 is] the seventh well-documented species in
European waters. Except for C. jubata, which is a deep-water species from depths of 350–1800 m, the other six
European species of Chaetozone all occur in subtidal sediments to depths of no more than 100 m." [details]

Etymology Malmgren p.96 (book version of article, or 206 in journal) gives the derivation from Greek in a footnote. Transcribing the lettering it refers to 'chaite' feminine, meaning hair, and 'zone' feminine, meaning belt, thus a belt of hair, in reference to the posterior girdle of spines characteristic of the genus. [details]

Grammatical gender Chaetozone is feminine, as both Greek words are feminine and Malmgren used a feminine ending for C. setosa, the type species. [details]

Habitat Known from seamounts and knolls [details]
