, excystment of the active juvenile is through a tubular portion released from the cyst, and is preceded by squirts of a foamy material. Thus, juvenile growth may lead to an increasing pressure on the inside of the cyst which could be instrumental in impelling the tubular portion through which the juvenile escapes from the cyst.
