Summary
The mean glycogen content ofM. fragilis is considerably higher than that of the allied speciesM. striata but is lesser than in the teredines. They derive their glycogen requirements mainly from plankton. The glycogen inM. fragilis is not size-dependent as it is influenced by factors like gonadial activity, composition of nutriments, feeding, etc. The glycogen content is higher in mature and gravid animals than in spent ones and decreases on starvation. An increase of glycogen has been recorded as the forms grow to maturity levels with a decrease in nitrogen content.
