People, dogs, cats, and elephants all have bilateral symmetry. Animals with radial symmetry have body parts arranged around a central point. Any line drawn from one side through the center to the opposite side will divide the animal into two symmetrical halves. Animals with radial symmetry have many lines of symmetry.

What animals have bilateral symmetry?
Examples of animals that possess bilateral symmetry are: flatworms, common worms ("ribbon worms"), clams, snails, octopuses, crustaceans, insects, spiders, brachiopods, sea stars, sea urchins, and vertebrates.
What is bilateral symmetry example?
*Bilateral symmetry means that the body can be divided along a plane that divides the animal into left and right sides. *Humans, dogs, and even sharks can exhibit bilateral symmetry.
What is the first animal group that exhibits bilateral symmetry?
''Plathelminthes'' is the first phylum to exhibit bilateral symmetry. Echinodermata have radial symmetry as adults but bilateral symmetry as larvae stage.
Are annelids radial or bilateral?
The Annelids are bilaterally symmetrical, triploblastic, coelomate, invertebrate organisms.
What animal has radial symmetry?
Radial symmetry is found in the cnidarians (including jellyfish, sea anemones, and coral) and echinoderms (such as sea urchins, brittle stars, and sea stars).
Do fishes have bilateral symmetry?
Mostly all marine organisms, including all vertebrates and some invertebrates are bilaterally symmetrical. This includes marine mammals such as dolphins and whales, fish, lobsters, and sea turtles.
Does reptiles have bilateral symmetry?
Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
Why are animals bilaterally symmetrical?
Having bilaterally symmetrical bodies (the same on both sides along an axis) permit them to propel forward in a straight line. In evolutionary history, animals that moved quickly and efficiently from point A to point B would have been more successful and selected for than those who were ineffective at locomoting.
Are jellyfish bilaterally symmetrical?
Despite the diversity within the jellyfish clade, Medusozoa, all 200 described jellyfish species exhibit radial symmetry. This means that their appendages radiate outward from a central point – akin to the spokes of a bicycle wheel.
Do butterflies have bilateral symmetry?
Butterflies and moths are great examples of creatures that show bilateral symmetry. They have a single line of symmetry down the middle of their body, meaning the patterns on their wings are the same on both sides.
What is bilateral symmetry in zoology?
Bilateral symmetry involves the division of the animal through a sagittal plane, resulting in two mirror-image, right and left halves, such as those of a butterfly, crab, or human body. Animals with bilateral symmetry have a “head” and “tail” (anterior vs.
Are snakes bilaterally symmetrical?
Animals have a long tradition of being bilaterally symmetrical - that is, of the left side and the right being nearly identical. ... Snakes and other elongate, limbless animals sometimes stagger their paired organs (gonads, kidneys) so that one is in front of the other, to better fit in their cylindrical bodies.
Do all animals have bilateral symmetry?
All true animals, except those with radial symmetry, are bilaterally symmetrical. ... Animals in the phylum Echinodermata (such as sea stars, sand dollars, and sea urchins) display radial symmetry as adults, but their larval stages exhibit bilateral symmetry. This is termed secondary radial symmetry.
Are narwhals asymmetrical?
One extraordinary tooth
The narwhal's long, spiraled tusk is unique–no other animal has anything quite like it. ... When both tusks erupt, they remain asymmetrical–one is always longer. Such asymmetry is found nowhere else in nature.
