| dc.description.abstract | The tube hood orientation of Pista pacifica is non-random and related to current direction. Results from field measurements and from one flow tank experiment suggest that Pista pacifica build their tube hoods at right angles to local currents, and perhaps away from the direction of any sediment transport which may occur normal to the prevalent current direction. By orienting their tube hoods perpendicular to water currents, the animals may be making use of the kinetic energy of the water motion around them to generate a tube ventilation current. This current may in turn lessen the energetic needs of the worms by providing internal ventilation and sediment flushing currents at little energetic cost to the organism. | en |
