Spawning and larval development of two tropical cowries (Gastropoda: Cypraeidae), and under laboratory conditions.

The spawning and larval culture of cowrie (family Cypraeidae) are both difficult and little known, in part due to the long planktonic period of most species. In this study, we describe the captive spawning behaviour and larval development of two tropical cowrie species, and . Both species brooded over their egg masses before hatching occurred and larvae were collected for culture under laboratory conditions.
