Pempheridae (Sweepers)
Etymology: Pempheris: Greek, pempheris = the name of a fish (Ref. 45335); analis: The name analis refers to the anal fin, but the exact reference is unknown (Ref. 88976).
More on author: Waite.
Environment: milieu / climate zone / depth range / distribution range
Ecologia
marino associati a barriera corallina; distribuzione batimetrica 5 - 40 m (Ref. 2334). Temperate
Southwest Pacific: Australia (including Western Australia and Lord Howe Island), Norfolk Island (Ref. 8879), the Kermadec Islands, and North Island, New Zealand (Ref. 27767).
Size / Peso / Age
Maturity: Lm ? range ? - ? cm
Max length : 20.0 cm TL maschio/sesso non determinato; (Ref. 2334)
Spine dorsali (totale) : 6; Raggi dorsali molli (totale) : 9 - 12; Spine anali: 3; Raggi anali molli: 30 - 38. This species is distinguished by the following set of characters: all scales strongly ctenoid (rarely 4 or fewer predorsal scales cycloid); no axillary scale; 63-77 lateral-line scales, usually 65 or more; 22-27 scales below lateral line; 30-38 anal-fin rays; ratio of preanal length to anal-fin base length 1.04-1.27; ratio of pelvic-fin origin to anal-fin origin to anal fin base length 0.28-0.44; anterior light organ associated with pyloric caeca absent (Ref. 88976).
A nocturnal species that form aggregations in caves by day and feeds on zooplankton at night (Ref. 2334). The smallest gravid female found was 8.61 cm SL and the largest 14.94 cm SL. These were found among collections made in October through March, although specimens from the early dates carried immature eggs. The smallest specimens, 3.03-3.18 mm SL from the Kermadecs, were collected in June, suggesting that juveniles settle early in the year. Over its entire range, collections are known from September to June (Ref. 88976).
