Where is bilateral symmetry found?
Bilateral symmetry is found in Platyhelminthes and Mollusca . If we draw a line from the interior and of the organism in Platyhelminthes to the posterior and then it will reflect each other forming bilateral symmetry which creates two matching halves.
Is earthworm bilateral symmetry?
Earthworms have bilateral symmetry . This means that if you cut the earthworm down the centerline, the left side of the body would be identical to the right side. Some species of earthworms have a tongue-like lobe above the mouth called prostomium.

What is difference between radial and bilateral symmetry?
The balanced distribution of the body shapes is referred to as the biological symmetry. ... The key difference between radial and bilateral symmetry is that radial symmetry generates identical body halves around the central axis whereas bilateral symmetry generates only two sides as left and right.
Is a jellyfish bilateral symmetry?
People, dogs, cats, and elephants all have bilateral symmetry . Animals with radial symmetry have body parts arranged around a central point. ... Some examples of these animals are jellyfish, sea urchins, corals, and sea anemones. A bicycle wheel also has radial symmetry.

Do humans have bilateral symmetry?
Symmetry and sex
The body plans of most animals, including humans, exhibit mirror symmetry , also called bilateral symmetry. They are symmetric about a plane running from head to tail (or toe).
Which of the following is bilateral symmetry?
