Yellow Encrusting Sponge Myxilla lacusnosa Sponges are the simplest of the multicellular animals. They have no organ systems and are characterized by numerous canals and chambers that open to the outside by way of pores which giving this phylum its name. Many sponges are asymmetrical, but some exhibit radial symmetry. They are almost plant-like in their simplicity and are often confused as being plants. The body plan of a typical sponge is shown in figure1. Water (carrying suspended plankton and other potential food) enters numerous small pores called ostia (singular, ostium). The ostia are surrounded by donut-shaped cells called porocytes that open and close to control water flow. For the sponge depicted in figure 1, water flows directly into an open chamber called the spongocoel (the term "coel" refers to an open space or body cavity in an animal). Water leaves the spongocoel by a larger opening (the osculum).
Sponges are asymmetrical.
There is no symmetry of a sponge body because the sponge grows to fit the space where they live
Sponges mostly have no symmetry, but it is possible to have a sponge that exhibits radial symmetry. They never have bilateral symmetry.
Sponges show no symmetry: they are asymmetrical.
Sponges are considered to be asymmetrical. Their body is not organised in any particular pattern.
None. It is said to be asymmetrical.
Radial
asymmetrical
Finger sponges do not have any type of symmetry. Finger sponges can grow fingers where ever they have space so they are asymmetrical.
Sponges do have some differentiated cells that have different functions but they don't have true tissues like all other animals and plants do. Even though they're included in the Animal kingdom they also symmetry, which most other animals have.
Tuna, like all fish, have bilateral symmetry.
Bilateral body plan.Meaning that the animal is similar to a shovel, it has a distinct front end (anterior end), a distinct back end (posterior end), a top or back (dorsal side), and a bottom or belly (ventral side), and the left and right sides are like mirror images.So think shovel: the head is the spade, and the handle is like the tail, it has a distinct top and bottom (since the spade part is usually bent upward), and the left and right sides look the same.For example: fish, humans, a lizard, dogs, and even worms have bilateral symmetry. Animals like sea anemones do not.

sponges have no symmetry animals with radial symmetry are radiata and cnidaria, like jellyfish
Sponges are asymmetrical, although a few species have nearly radial symmetry.
Sponges mostly have no symmetry, but it is possible to have a sponge that exhibits radial symmetry. They never have bilateral symmetry.
Sponges really don't have any kind of symmetry.
Sponges really don't have any kind of symmetry.

Sponges are asymmetrical. Organisms in Cnidaria have radial symmetry while organisms in Arthropoda exhibit bilateral symmetry.
an asymmetrical body plan
Sponges are asymmetrical. They have no symmetry.
Asymmetrical are organisms, such as sponges, that have no true symmetry.
Most sponges of the Demospongiae type are considered asymetrical. (Not having symmetry.)
