| Once it reaches the final site, the larva transforms into a sporocyst, which is little more than an amorphous, germinal sac. |
| When stripped of their swimming tunic, these young distomes have the form of a bag, which for a long time was called a sporocyst. |
| Second, it can encyst inside a daughter sporocyst as a metacercariae, be voided with the sporocyst, and then be consumed by the benthic-feeding definitive host, rosyside dace. |
| The Cercari are developed from spherical masses of cells found in the body cavity of the sporocyst or Redia. |
| Within the sporocyst, a special form of asexual reproduction, known as polyembryony, then occurs. |
| We sometimes find the cercarian age passed over, and the young distomes appear abundantly without tails in the sporocyst. |
