has a similarly broad diet. Because of their large, bulky nature, cephalaspid egg masses may be more easily entered by oophagous slugs than the narrower egg strings of other heterobranchs, and thus constitute preferred prey; alternatively, oophagous slugs may be more apparent within transparent cephalaspid egg masses and thus simply be more frequently observed feeding on cephalaspidean embryos. The sand bar at Cedar Key has a rich invertebrate fauna that includes diverse heterobranchs that could produce egg masses serving as suitable prey:
