The osphradium is a putative chemosensory organ of aquatic molluscs. Previously, we identified two distinct types of primary sensory neurons in the osphradial ganglion of freshwater pulmonates, one immunoreactive to leucine-enkephalin (LEnk...
Localization of the Chloroperoxidase of the Capitellid Polychaete Notomastus lobatus [0.03%]
螠虫动物Notomastus lobatus头足氯过氧化物酶的定位分布

K S Yoon et al.
Antisera against the two constituent proteins of the chloroperoxidase enzyme of the capitellid polychaete Notomastus lobatus were used to identify and localize these polypeptides by immunoblotting and indirect immunofluorescence. Immunofluo...
In Vivo Studies of Suspension-Feeding Processes in the Eastern Oyster, Crassostrea virginica (Gmelin) [0.03%]
活体过滤实验:关于Crassostrea virginica的悬浮取食过程研究

J E Ward et al.
Suspension-feeding processes in the eastern oyster Crassostrea virginica (Gmelin, 1791) were examined, in vivo, with an endoscope linked to a video image-analysis system. We found that many of the previously published concepts of particle t...
Energetics of the Ventilatory Piston Pump of the Lugworm, a Deposit-feeding Polychaete Living in a Burrow [0.03%]
沟虫的通气活塞泵的能量效应研究——以穴居多毛纲动物为例

The aim of this study was to tentatively estimate the energy cost of breathing in the lugworm, Arenicola marina (L.), a gallery-dwelling, piston-pump breather that moves water in a tail-to-head direction. Each tested lugworm was placed in a...
Changes Occur in the Central Nervous System of the Nudibranch Berghia verrucicornis (Mollusca, Opisthobranchia) During Metamorphosis [0.03%]
