Neuromuscular Activity in the Swimming Sea Anemone, Stomphja
The spontaneous activity and responses to electric stimulation of actinians have been intensively studied (e.g. Pantin, 1935a, b, c, d; Ross, 1952, 1957a, b; Horridge, 1958) for the light which they might throw on the functioning of the 'elementary nervous system', i.e. a nervous network lacking the physical concentration of neurones found in ganglia and brains. It seems desirable to add to thi...
متن کاملA Study of the Muscular Anatomy and Swimming Behaviour of the Sea Anemone
The sea anemone Stomphia coccinea, when touched by certain starfishes, frees itself from the substratum, and by a series of waving motions propels itself through the water. This locomotion has been studied by means of direct observation and by analysis of time-lapse, and normal-speed motion-picture films. Ecological observations and stimulation tests made in the natural environment of the anemo...
متن کاملA Transmesogloeal Conduction System in the Swimming Sea Anemone Stomphia
1. A conduction system in Stomphia transfers information across the mesogloea from ectodermal receptors to endodermal effectors. 2. In the column, this transmesogloeal system has numerous and widespread connexions. 3. It is suggested that the connexions may be processes from multipolar nerve cells located in the endoderm. 4. Certain aspects of behaviour are controlled by this conduction system ...
متن کاملAnimating the Escape Response of Stomphia coccinea from Dermasterias imbricata Modeled Using Implicit Surfaces
Many of the most interesting behaviors in the biological world have to do with interactions between species. The predator-prey interactions among aquatic organisms is an interesting part of the natural world which has not been seen much in computer animation. This paper explores the interaction between various sea anemones and the starfish Dermasterias imbricata. Although a simulation between a...
متن کاملModeling the Structure of the Sea Anemone, Stomphia Coccinea and the Sea Star, Dermasterias Imbricata Using Implicit Surfaces
The BlobTree provides a hierarchical data structure for the definition of complex models built from implicit surfaces, CSG Boolean operations and space warping functions. The implicit model within the system is defined as a hierarchical composition of multiple objects. In this paper, we describe an application of the BlobTree to create visually accurate models of two invertebrates, the sea anem...
