The pelagic foraminifera Hastigerina inhabits tropical and subtropical seas. Adults inhabit surface waters and are carnivorous. At the initiation of reproduction the bubble capsule fuses and the barbs and septa are reduced. The formanifera thus sink to around 200 m depth, whereupon isogametes appear from the calciferous shell. The young form a new shell and rise during growth to inhabit the surfaces waters. The cycle lasts 1 lunar month. Including animated sequences.
