What type of symmetry do cats have?
bilateral symmetry
What kind of symmetry does a starfish have?
five-sided symmetry
What animals have no bilateral symmetry?
Importantly, she notes, not all animals are bilaterally symmetrical. Some animals have radial symmetry with four or five axes, like starfish, jellyfish and sea urchins. The only creature on Earth who is not symmetrical in any way is the sponge.
How many planes can divide a jellyfish into two symmetrical parts?
Biradial symmetry is an intermediate where the organism can be divided, like radial symmetry, but in two planes only. The Ctenophora phylum, or comb jellies, have a biradial body plan and many believe that this body plan is an evolutionary stepping-stone from radial to bilateral symmetry.
What body part is symmetry?
Symmetry, in biology, the repetition of the parts in an animal or plant in an orderly fashion. Specifically, symmetry refers to a correspondence of body parts, in size, shape, and relative position, on opposite sides of a dividing line or distributed around a central point or axis.
Are jellyfish radially symmetrical?
Jellyfish and many other marine animals such as sea urchins, sea stars, and sea anemones have what is known as radial symmetry.
Why do jellyfish have radial symmetry?
This form of symmetry marks the body plans of many animals in the phyla Cnidaria, including jellyfish and adult sea anemones (Figureb, c). Radial symmetry equips these sea creatures (which may be sedentary or only capable of slow movement or floating) to experience the environment equally from all directions.
Is jellyfish is a regeneration?
Jellyfish are animals that possess the unique ability to regenerate body parts. A team of scientists has now revealed the cellular mechanisms that give jellyfish these remarkable ‘superpowers. Jellyfish are animals that possess the unique ability to regenerate body parts.
Do corals have radial symmetry?
This form of symmetry marks the body plans of animals in the phyla Ctenophora (comb jellies) and Cnidaria (corals, sea anemones, and other jellies). Radial symmetry: Some organisms, like sea anemones (phylum Cnidaria), have radial symmetry.
