1. Arenicola ecaudata differs not only in structure, but in mode of life, from A. marina . Our results indicate that there are also great differences in behaviour physiology. 2. The brainless isolated extrovert of ecaudata traces a continuous, or nearly continuous, background of activity, upon which prominent spells of vigorous rhythmic contraction appear at intervals of the order of 30-40 min. Similar spells are sometimes shown by the corresponding preparation from marina , whose…

It is suggested that, because of their relatively simple repertoires of behavior, polychaetes may be particularly useful in behavioral research. An interesting range of responses has already been
Boxfishes (Teleostei: Ostraciidae) as a model system for fishes swimming with many fins: kinematics.
Swimming movements in boxfishes were much more complex and varied than classical descriptions indicated and despite their unwieldy appearance and often asynchronous fin beats, boxfish swam in a stable manner.

The Ecophysiology of Sandy Beach Animals — A Partial Review
Although laboratory and field experimentation forms an essential aspect of ecophysiology, it is convenient and appropriate to include under this heading the entire study of behaviour, quite regardless of whether the behaviour has been induced experimentally or simply observed in the field.


The integration of activity cycles in the behaviour of Arenicola marina L.
Cyclic behaviour patterns were found, remarkably similar to those which intact worms exhibit under favourable conditions, and in which two components were conspicuous: feeding cycle and extrovert trace, which appear to compete for territory.
The anatomy of the body wall and appendages in Arenicola marina L., Arenicola claparedii Levinsen and Arenicola Ecaudata Johnston
The main layers of the body wall are described and there are grounds for supposing that the circular muscle layer plays a greater part than the longitudinal in the maintenance of a postural fluid pressure in active worms.
