The Distribution of Glycogen in the Shipworm, Teredo (Lyrodus) Pedicellata Quatrefages
Abstract:Adult Teredo pedicellata has been shown to contain approximately 30% glycogen on the basis of its dry weight. This figure is achieved within six weeks after the borer first invades wood. Most of the glycogen is concentrated in the mantle, the muscles and the gills.
Teredids maintained in substantially plankton-free sea water for seven days showed no significant change in glycogen content. When denied access to wood for seven days there was a decrease of 72% in glycogen content.
The large prenatal reserves of glycogen are largely consumed during the free-living period of seventy-two hours that precedes invasion of wood by larval teredids.
