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.
Nope, there are some that are asymmetrical. Like sponges.
Yes they are very symmetrical animals. So yea.
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.
nope. Some bivalves have bilateral symmetry but no radial symmetry.

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.
No, They are bilaterally symmetrical. Radially symmetrical animals include echinoderms (starfish, sea stars, sea urchins) and many plants.
An antimere is one of the two halves of bilaterally symmetrical animals.
In terms of symmetry, only certain letters can be considered symmetrical. These include letters such as A, H, I, M, O, T, U, V, W, X, and Y. These letters have either vertical, horizontal, or diagonal symmetry, meaning they can be divided into two equal parts that mirror each other. Other letters like B, C, D, E, K, and S do not have symmetry and are considered asymmetrical.
those animals which are bilateral symmetrical are triploblastic and triploblasts are more successful and diplobalsts(radial symmetrical) due to their complex body organization
not all, but some
It can be in some cases.
