  journal={Journal of Morphology},
An examination of the cuticle of six aquatic oligochaete species using transmission electron microscopy revealed a larger morphological variation than previously known. Three freshwater species, Aulodrilus pluriseta, Spirosperma ferox (both Tubificidae), and Pristina breviseta (Naididae), and three marine species, Clitellio arenarius, Heterochaeta costata (both Tubificidae), and Paranais litoralis (Naididae), were investigated. The arrangement of the collagen fibers in the cuticle differs among… 
Ultrastructure of the body wall of three species of Grania (Annelida: Clitellata: Enchytraeidae)
The body wall of three species of Grania, including the cuticle, epidermis and the musculature, are studied using TEM and it is concluded that neither cyanobacteria nor epidermal pigment granules were present in the fixed material.
An ultrastructural study of the cuticle in the marine annelid Heterodrilus (Tubificidae, Clitellata)
The variation in the morphology of the cuticle appears to be dependent on both phylogenetic constraints, and functional and environmental factors.
Comparative structure of the epidermis in polychaetes (Annelida)
This paper reviews the recent literature on the annelid epidermis, focussing on the mentioned cell types and the cuticle, and indicates thatannelid cuticular collagen differs in several aspects from collagen of the connective tissue and might be of interest for systematics.
Histology and Mucous Histochemistry of the Integument and Body Wall of a Marine Polychaete Worm, Ophryotrocha n. sp. (Annelida: Dorvilleidae) Associated with Steelhead Trout Cage Sites on the South Coast of Newfoundland
Questions regarding the nature and cellular source of the mucus were addressed in this study and the role of mucus secretion is discussed.
A probable oligochaete from an Early Triassic Lagerstätte of the southern Cis-Urals and its evolutionary implications
Oligochaetes, despite their important role in terrestrial ecosystems and a tremendous biomass, are extremely rare fossils. The palaeontological record of these worms is restricted to some cocoons,
Global panorama of studies about freshwater oligochaetes: main trends and gaps
Freshwater oligochaetes have been studied over the years in a wide range of habitats around the world. To analyse the data published about freshwater oligochaetes in the 31 year period between 1985
Histochemical and ultrastructural analysis of the epidermal gland cells of Branchiomma luctuosum (Polychaeta, Sabellidae)
The complex composition of the mucus produced by epidermal gland cells of B. luctuosum may be correlated with its different functions.
Tubificids with trifid chaetae: morphology and phylogeny of Heterodrilus (Clitellata, Annelida)
Heterodrilus is a marine group of small (3-25 mm) clitellates that occur interstitially in sandy sediments from the intertidal zone down to about 150 m depths. The taxon includes 42 valid species a


Morphological Investigation of the marine tubificid Clitellio arenarius (Annelida, Oligochaeta)
The paired spermathecae, which contain spermatozeugmata after copulation, each consists of a narrow duct and a voluminous ampulla, and the female and male genital ducts consist of paired sperm funnels, vasa deferentia and atria which terminate in penes.
Morphology and phylogenetic implications of oesophageal modifications in the Limnodriloidinae (Oligochaeta, Tubificidae)
Two features have been considered apomorphic for the subfamily Limnodriloidinae (Tubificidae): the lobed prostate glands, which are broadly attached to prostatic pads inside the atrial ampullae, and
An Ultrastructural Study of the Distal Epidermis and the Occurrence of Subcuticular Bacteria in the Gutless Tubificid Phallodrilus Albidus (Oligochaeta:Annelida).
The typically annelid cuticle of Phallodrilus albidus has an increased population density of epicuticular projections, but this is not thought to be related to its gutless condition. The irregular
A fine structural analysis of the epidermis and cuticle of the oligochaete aeolosoma Bengalense stephenson
The fine structure of the epidermis and cuticle has been described for the oligochaete Aeolosoma bengalense and evidence supports a microvillar origin for the cuticular surface particles.

The anatomy of Phallodrilus planus Erseus, 1979, a relatively large interstitial tubificid from shallow subtidal sands off Bermuda, is characterized by an unequal development of the muscular layer
Morphogenesis of the Genital Ducts and Spermathecae in Clitellio arenarius, Heterochaeta costata, Tubificoides benedii (Tubificidae) and Stylaria lacustris (Naididae) (Annelida, Oligochaeta)
The development of the male genital ducts in Clitellio arenarius, Tubificoides benedii, Heterochaeta costata (Tubificidae) and Stylaria lacustris (Naididae) is studied with the purpose of
Development of the genital ducts and spermathecae in the Rhyacodrilines Rhyacodrilus coccineus and Monopylephorus rubroniveus (Oligochaeta, Tubificidae)
The male genital duct in Tubificidae consists of a funnel, a vas deferens, an atrium, and, frequently, a copulatory structure. There may also be a diffuse or compact prostate gland in association
Comparative ultrastructural study on tris 1‐aziridinyl phosphine oxide prefixed cuticles of some oligochaetes
The conclusion is that phosphotungstic acid binds to polysaccharides which do not contain vicglycol groups nor active sites responsible for the positive reaction with lead and uranyl salts.
