Extract

The rate of excretion of ammonia by Nassarius decreases progressively during starvation. Both Nassarius and Buccinum exhibit a transient peak of ammonia excretion some 16–48 h after a meal. In Nassarius the length of the delay between feeding and maximum ammonia excretion depends on the duration of prior starvation.
