[Click photo for picture page]
|Habitat:||Intertidal. Soft shore. Enclosed harbours and sheltered bays. Fine muddy sand Infaunal. Depth range: 0-1 (m). Salinity regime: Estuary-like variation. Microhabitat: Upper- to mid- shore, near surface Tube: impermanent meandering burrows|
|Occurrence:|| Common to abundant. Density: 1000-3000 (m2).
Distribution in NZ: New Zealand wide
|Feeding guild:||Data unavailable.|
|Diagnosis:||Genus Capitella in Family Capitellidae.
A species complex. This description applies to a small New Zealand estuarine species of unpolluted locations. Prostomium oval, eyespots rare. Nine thoracic segments, all with chaetae. Capillaries first 5 chaetigers only (less often range 3-7, age dependant), hooded hooks thereafter except rarely in males when dorsal genital spines present, 2 pair on 8, 1 pair on 9. Colour: None. Pale body only coloured by blood cells. Maximum size: 10 mm total length, 0.3 mm body width.
|Notable aspect:||Blunt rounded prostomium.|
|Comparisons:||Confusable with oligochaetes (in which chaetae are single), and Heteromastus filiformis (pointed prostomium, anal cirrus, more anterior region chaetigers)|
|Taxonomy:||This taxon represents a complex of morphologically similar or identical species (mostly unnamed). Much larger individuals occur at NZ organically-enriched subtidal environments, with capillaries on first 7 chaetigers, and males with up to 6 pairs of genital spines. These may be another species.|
|Distribution:||Unknown. However the Capitella capitata complex is world-wide.|
|Biology:||A mid- to upper-shore species in fine sand to mud. Reproduction with large yolky eggs, probably with minimal or no planktonic dispersal, probably year-round with short lifespan (multivoltine), with population densities fluctuating with environmental conditions.|
