This sporocyst changes colour, pulsates, flashesbright colours and looks quite like a caterpillar or maggot.

这些胞蚴能够改变颜色、搏动，闪烁着明亮的颜色，使其看起来像毛虫或蛆虫。

Now a second sporocyst is then formed from that, which develops in the eye stalk or tentacleof the snail.

现在第二代胞蚴从中形成了它们，使蜗牛发育出了眼柄或触角。

Once the parasite is consumed by the snail , it transforms into a form called the sporocyst, which infects the snail's gut.

一旦彩蚴吸虫被蜗牛吃掉，它就转变成了胞蚴，能感染蜗牛的肠道。
