Feeding behavior of the cirratulid Cirriformia filigera (Delle Chiaje, 1825) (Annelida: Polychaeta).

Correction: The Multitentaculate Cirratulidae of the Genera Cirriformia and Timarete (Annelida: Polychaeta) from Shallow Waters of Brazil

A large number multitentaculate cirratulids have been described worldwide but most are only known through the original descriptions. Type material, voucher and recently collected specimens from Brazil were revisited in order to reveal their true identity and confirm the records of widely distributed species in this region. Six species are described, three of which are new, Cirriformia capixaben...

The Oweniidae (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) with the description of two new species of Owenia Delle Chiaje, 1844.

Study of the Oweniidae specimens (Annelida; Polychaeta) from Lizard Island (Great Barrier Reef, Australia) stored at the Australian Museum, Sydney and newly collected in August 2013 revealed the presence of three species, namely Galathowenia quelis Capa et al., 2012 and two new species belonging to the genus Owenia Delle Chiaje, 1844. Owenia dichotoma n. sp. is characterised by a very short bra...

The ultrastructure of calcareous cirratulid (Polychaeta, Annelida) tubes

The entire tube wall of Dodecaceria caulleryi and D. coralii is composed of thin calcareous lamellae with a spherulitic prismatic ultrastructure. In Diplochaetetes mexicanus the tube ultrastructure is similar, but contains also some lamellae with a homogeneous structure. The biomineralization system of cirratulids has not evolved since the appearance of calcareous tubes in the Oligocene. The tu...

Short communication: The first report of Amphipholis squamata (Delle Chiaje, 1829) (Echinodermata: Ophiuroidea) from Chabahar Bay – northern Oman Sea

Feeding Ecology of Nereis diversicolor (O.F. Müller) (Annelida, Polychaeta) on Estuarine and Lagoon Environments in the Southwest Coast of Portugal

The feeding ecology of Nereis diversicolor (O. F. Müller, 1776) (Annelida: Polychaeta) was studied over 14 months at three estuarine-lagoon systems of the Southwest coast of Portugal (Odeceixe, Aljezur and Carrapateira). The analyses of digestive tract revealed that diet change according to site, period of the year and individual sizes. There are no differences in the digestive contents between...
