Classification of Bivalvia
The Bivalvia are wholly aquatic benthos that have undergone secondary degeneration from the condition of the ancestral mollusk (possibly, but not certainly, a monoplacophoran-like animal; Yonge,Expand

A Study in Jet Propulsion: An Analysis of the Motion of the Squid, Loligo Vulgaris
1. A method is presented which allows the jet thrust and motion of a cephalopod to be calculated from basic information on its shape and material properties. 2. A simple model is used to illustrateExpand

  • 24 January 1967
The digging activity of Ensis arcuatus shows six stages, together termed the 'digging cycle' which are repeated cyclically and are similar to those of other burrowing bivalves. A digging cycleExpand

The Mechanism of Burrowing of the Mole Crab, Emerita
1. The mechanism used by the mole crab Emerita for burial in sand has been studied by the analysis of cine film and electronic recordings. 2. Digging is initiated by tactile stimulation of the baseExpand

Jet propulsion in salps (Tunicata: Thaliacea)
This paper describes the locomotion of salps by jet propulsion, from a combination of measurements of chamber pressures, static thrust, and electromyographic activity, with kinematic records ofExpand

Jet propulsion of the calycophoran siphonophores Chelophyes and Abylopsis
Jet propulsion in the small siphonophores Chelophyes and Abylopsis was investigated by measuring chamber pressures and thrust exerted in tethered nectophores, and by cinephotography of free swimmingExpand

Observations on Certain Mechanical Properties of the Ligament of Pecten
The ligament of Pecten maximus consists of two layers, the outer extending along the dorsal margin of the valves, and the inner situated between the valves in the region of the umbo. The formerExpand

4 – Locomotion in Molluscs
Publisher Summary This chapter provides an overview of locomotion in molluscs. Locomotion is achieved either by ciliary action or by muscular locomotory waves. Mucus plays an important role inExpand
