cnidarians
true
Assuming you mean two symmetrical sides, the term is called bilaterally symmetric.
Bilaterally symmetric animals have a central nervous system.
bird
An antimere is one of the two halves of bilaterally symmetrical animals.
It is true.
Anterior refers to the head end of a bilaterally symmetrical animal. The word posterior refers to the rear end or tail end.
In taxonomy, the phylum is a major category towards the top of the heirarchial tree. Notwithstanding there are several classifications above (higher). Arthropods are directly below a taxon Panarthropoda, which is under Ecdysozoa (moulters with a certain description of cuticle), Protostomia (bilaterally symmetric with a certain germ layer configuration), Bilateria (bilaterally symmetric); Eumetazoa (true tissues, with a certain embryonic phase), Metazoa (animals with a fixed type of body plan); Opisthokonta (broad taxon of eukaryotes with organized cell nuclei and certain other characteristics); Eukaryota (distinct cell nuclei); which falls under cellular organisms.
Arthropods are classified by examining their structure and comparison to characteristics considered typical of the phylum. Thes properties include segmented bodies, an exoskeleton made from chitin, and joint appendages.

True. The majority of radially symmetric animals, such as jellyfish and sea anemones, are aquatic, as their body design is well-suited for movement and feeding in water environments.
Cnidarians are true radially symmetrical animals. They include jellyfish. Echinoderms (like starfish) also display radial symmetry. It is important to note that the larvae of echinoderms are bilaterally symmetrical and that Echinoderms evolved from a bilaterally symmetrical group.
No, They are bilaterally symmetrical. Radially symmetrical animals include echinoderms (starfish, sea stars, sea urchins) and many plants.
