Technically seen, symmetrical animals do not exist. If you take an image of an animal/face/organism, and mirror it with Photoshop on the supposed line of symmetry, you will find that the end result, no matter how well edited, will look non-natural. To be symmetrical to a half, the genes of the other half have to be exactly the opposite. There are no known scientific cases where "inverse" genes on one half have been found, so, in short, the answer to your question is: There are no "symmetrical animals.

Some of the general features of acoelomate animals include internal cavity for digestion, bilateral symmetrical, organ system organization and so on. These features are the ones that distinguish acoelomate animals.
Do mollusks have radially symmetry?
nope. Some bivalves have bilateral symmetry but no radial symmetry.
In what bilaterally symmetrical animals is there only one ovary?
bird
Give an example of asymmetrical animals?
Butterflies. Many animals are more or less symmetrical, with exceptions like crabs and lobsters which have one much larger claw, and some animals like flatfish which have evolved from a symmetrical ancestor in such a way as to favour one side only. Among humans, asymmetrical bodies or features are perceived as uglier, or as deformed, so there may be strong selection pressures to choose a more symmetrical mate. Animals which are super-symmetrical include peacocks, butterflies and patterned mammals such as tigers, leopards and ocelots. The last three are particularly symmetrical in their facial markings, which suggests that it gives a selection advantage.
Do mollusks have symmetry?
No, They are bilaterally symmetrical. Radially symmetrical animals include echinoderms (starfish, sea stars, sea urchins) and many plants.
What is an antimere?
An antimere is one of the two halves of bilaterally symmetrical animals.
Which letters are symmetrical?
Some letters, like A are left-right symmetrical but not up-down symmetrical. Some letters, like B, C, or D are up-down symmetrical but not left-right. Letters like H, I and O are both.
What are the advantages to bilateral symmetry?
those animals which are bilateral symmetrical are triploblastic and triploblasts are more successful and diplobalsts(radial symmetrical) due to their complex body organization
Are polyhedrons symmetrical?
not all, but some
Is a paralellogram symmetrical?
It can be in some cases.
