This study provides new information about the composition, diversity and zoogeography of abyssal polychaetes in the little-studied South Eastern Atlantic (Angola Basin). During the austral winter of 2000, twenty-five box core samples (total area sampled 6 m) were taken along a 500-km transect in five work areas at depths exceeding 5000 m. A total of 1047 individuals representing 86 species belo...

Eight new species of cirratulid polychaetes of the genus Chaetozone from the Alaskan (Beaufort Sea) and Canadian Arctic (Baffin Island, Baffin Bay, Labrador, Hudson Strait, and Hudson Bay) and the Northeastern Pacific are reported together with two new species of Tharyx from the Alaskan Beaufort Sea and the Strait of Juan de Fuca. The new species of Chaetozone and Tharyx are compared with relat...

survey of macrobenthos of kolahy and tiab estuaries was carried out in 1996 - 1997. in this research, 25 macrobenthos genera in tiab and 30 macrobenthos genera in kolahy were identified. t-test showed there was no significant difference between macrobenthos population of both estuaries. the z-test showed, that there were well correlation between macrobenthos populations and season in both estua...

In recent years it has become evident that many marine invertebrates are sensitive to changes in hydrostatic pressure, and the subject has recently been reviewed by Knight-Jones & Morgan (1966). Most are planktonic forms, and their responses appear to be of a depth-regulatory nature (Baylor & Smith, 1957; Moore & Corwin, 1956). However, a few normally benthic types have also been shown to be pr...

Three species of scale-worms inhabiting chaetopterid tubes have been found during routine studies of benthic communities. Anotochaetonoe michelbhaudi gen. et sp. nov. occurred in the E Atlantic off Congo in association with Spiochaetopterus sp. and Phyllochaetopterus sp. It has a relatively short body (fewer than 50 segments); elytra in posterior part of the body arranged on chaetigers 23, 26, ...

Paramaldane, new genus, with type species Paramaldane glandicincta sp. n., and Maldane adunca sp. n. (Maldanidae, Polychaeta) are described based on material from the coast of south China. The new genus Paramaldane is similar to Maldane Grube, 1860 and Sabaco Kinberg, 1867, but it clearly differs from all genera within the subfamily Maldaninae by a unique combination of characters: the cephalic...
