Only members of the phylum Porifera (sponges) have no body plan symmetry. There are some fish species, such as flounder, that lack symmetry as adults.

What animals have body symmetry?
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 are the 4 types of animal symmetry?
The vast majority of animals, however, exhibit a definite symmetrical form. Four such patterns of symmetry occur among animals: spherical, radial, biradial, and bilateral.
What are the non bilateral animals?
The non-bilaterian animals comprise organisms in the phyla Porifera, Cnidaria, Ctenophora and Placozoa. These early-diverging phyla are pivotal to understanding the evolution of bilaterian animals.
Are frogs asymmetrical animals?
Frogs might hop in circles. Bilateral (or two-sided) symmetry in the body, like having an even number of legs and arms, can help you move around. ... Then there are a small number of animals on our planet that do not have symmetry. They are asymmetrical, like the sea sponges that live in the ocean.
Which animal lacks symmetry has no embryonic tissues and has intracellular digestion?
Lacking a true digestive system, sponges depend on the intracellular digestive processes of their choanocytes for their energy intake.
What are the 3 types of body symmetry?
Animals can be classified by three types of body plan symmetry: radial symmetry, bilateral symmetry, and asymmetry.
Do reptiles have bilateral symmetry?
Bilateral symmetry is characteristic of the vast majority of animals, including insects, fishes, amphibians, reptiles, birds, mammals, and most crustaceans.
Is the human body symmetry?
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).
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).
Are snails symmetrical?
Snails are similarly asymmetric in their appearance, and more obviously so: the shells and bodies of some snails twist around to the right, whereas others twist to the left. ... "Animals tend to be outwardly symmetric in appearance but are almost all asymmetrical inside," says Angus Davison of The University of Nottingham.
Do zebras have bilateral symmetry?
Zebra stripes are bilaterally symmetrical.
Are starfish asymmetrical?
Only sponges (phylum Porifera) have asymmetrical body plans. Some animals start life with one type of body symmetry, but develop a different type as adults; for example, sea stars are classified as bilaterally symmetrical even though their adult forms are radially symmetrical.
Are crabs asymmetrical?
The animals we tend to think of as asymmetrical - the Fiddler Crab, for example - that's one really famous example. It is actually a symmetrical creature. A lot of these so-called asymmetrical animals actually start off being symmetrical at some stage.
What is jellyfish symmetry?
Like all members of the phylum, the body parts of a jellyfish radiate from a central axis. This “radial symmetry” allows jellyfish to detect and respond to food or danger from any direction. Jellyfish have the ability to sting with their tentacles.
