Question

what are the larval stages of platyhelminthes

Answer 1

Explanation:

The larva, called a miricidium hatches and enters the body of a snail. Within the snail's body cavity it grows into a large sac called a sporocyst, and this then hatches into a further larval stage called the redia. The redia has a mouth and gut and migrates to the snail's digestive gland.

Flatworm, also called platyhelminth .

• Their body is dorsoventrally flattened.

• They exhibit bilateral symmetry.

• Also, they are triploblastic, with three germ layers.

• They do not have a body cavity and are acoelomate.

• The body is soft and unsegmented.

• They are mostly parasitic with a few free-living.

${ \mathfrak{ \orange{ \underline{ \underline{Larval \: stage}}}}}$

Platyhelminthes have 4 larval stages :

1. Miracidium
2. sporocysts
3. rediae
4. cercariae

The first larval stage, the miracidium, generally is free-swimming and penetrates a freshwater or marine snail, unless it has already been ingested by one.

Within this intermediate host, the parasite passes through a series of further stages known as sporocysts, rediae, and cercariae .
