Abstract
Whole colonies are detached from hermit crab shells and transferred to 4-in. glass finger bowls where they attach themselves to the glass. The bowls are separated by squares of coarse galvanized iron wire netting and stacked. A continuous gentle stream of unfiltered sea water is delivered into the top bowl and allowed to trickle down into those below supplying food and aeration. At Woods Hole, Massachusetts, males removed from colonies in June and cultured as above reach the adult female stage by end of August. Small spat may not produce eggs until the next summer, but winter well in culture. Adult females should be accompanied by small individuals which will develop the male phase and fertilize the eggs.
