Living Material

These snails are very hardy and can be maintained in the laboratory in good breeding condition for a prolonged period. A new batch of adults usually takes several days to become acclimatized before they begin to spawn. As many as 250 animals can be kept in a large aquarium, provided there is a continuous flow of fresh sea water; however, 100 snails will provide an adequate supply of eggs for most purposes.

One or more minced clams should be provided for food every day.

A smaller number of adults (about 25 to 30) can be kept for at least a month in standing, aerated sea water, if they are removed to a separate container for feeding and then returned to the aquarium. This makes possible their use for certain types of embryological experiments at inland laboratories, where running sea water is not available. See "Special Comments" below.

If the wooden ends of the aquaria commonly used at Woods Hole are covered with removable glass plates, collection of egg capsules is greatly facilitated.
