The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
Symmetry in biology is the balanced distribution of duplicate body parts or shapes. The body plans of most multicellular organisms exhibit some form of symmetry, either radial symmetry or bilateral symmetry or "spherical symmetry". A small minority exhibit no symmetry (are asymmetric).
Sponges are asymmetrical. Organisms in Cnidaria have radial symmetry while organisms in Arthropoda exhibit bilateral symmetry.
Sponges are asymmetrical, although a few species have nearly radial symmetry.
the same type as blue footed underwater donkeys.
Many jellyfish have four radial root canals and thus exhibit tetramerous radial symmetry. This form of radial symmetry means it can be divided into 4 equal parts
Adult Hemichordates exhibit bilateral symmetry, meaning their bodies can be divided into two similar halves along a single plane. However, during their larval stage, some species of Hemichordates show a form of metameric or radial symmetry.
Bilateral (meaning that it is symmetrical only is divided alone onle specific line. Radial symmetry means that the object can be symmetrical when divided along more that one different line.)
