also resembles Ablerus macchiae (Annecke & Insley, 1970) and Ablerus separaspidis (Annecke & Insley, 1970) with regard to the forewing having an infuscated crossband below marginal vein, but is distinguished from them by the different form of the infuscated crossband and ciliation
on disc of forewing.
HMDS drying also provided excellent results in the preservation of microstructural characteristics such as ciliation
of scallop feeding organs, as illustrated in the gills and labial palps of A.
Functional and evolutionary implications of opposed bands, big mouths, and extensive oral ciliation
in larval opheliids and echiurids (Annelida).
in the adenocarcinoma was not described in the previous report, whereas ciliation
in the tubular structure of the adenocarcinoma was evident in the present case.
Although feeding by these larvae has not been observed directly, their small size, abundant ciliation
, and the presence of an anterior invagination all suggest that these larvae are planktotrophic (Fadlallah and Pearse 1982a).
Anterior internal anatomy: Pedal pit shallow, <1/2 body width; foot single ridge 30 pm at widest; mouth opening ventrally at vestibule entrance; body wall musculature with weak circular and longitudinal fibers, the latter thickest ventrally; vestibular papillae one per root, few, vestibular ciliation
with two lateral tracts united posteriorly in U-shape, without frontal extension; pharynx surrounded by circular muscles; large paired anteroventral ganglia 45 [micro]m in diameter, posterior to pedal pit, with two commissures; cerebral ganglion 100 [micro]m wide, 70 [micro]m high; pharynx 65 pm long, surrounded by musculature and intercellular glands; no esophagus; unpaired, short midgut cecum.
We examined the organization and behavior of velar ciliation
in nonfeeding larvae of several species of Littorina, using light and scanning electron microscopy.
To enhance a classification of the major developmental stages of the thoracic bud, we also documented the expression pattern of acetylated tubulin as a marker for ciliation
Estimated ciliary band length-specific clearance rates are slight underestimates, as they were calculated by assuming that band length was equivalent to circumference at the prototroch, but a small portion of that circumference was interrupted by a dorsal gap in the feeding ciliation
collaris after ciliation
are in the range of 4-5 [micro]m, whereas those for the nemertean Carinoma tremaphoros, the polychaetes Nereis limbata and Polygordius sp.
Despite some remarkable work in the earlier studies, important aspects have not been adequately or coherently covered, such as ciliation
, type of filament growth, and creation of junctions.
It would indeed be a very remarkable example of convergence if these structures should all have evolved convergently from an ancestral uniform ciliation
