What else can I help you with?
Does a hydra have bilateral or radial symmetry?
The hydra has radial symmetry. The hydra belongs to the phylum Cnidaria and many immobile species in this phylum exhibit radial symmetry. Some marine animals that have bilateral symmetry are fish, sea turtles, and marine mammals.
Do all animals exhibit bilateral symmetry?
No, not all animals exhibit bilateral symmetry. Some animals, like jellyfish and sea anemones, exhibit radial symmetry instead.
Which creatures has radial symmetry?
Some examples of creatures with radial symmetry include jellyfish, sea stars, and sea urchins. These animals have body parts arranged symmetrically around a central axis, allowing them to move and feed in all directions.
What groups of animals have radial symetry?
Echinoderms (ex: starfish), cnidarians (ex: jellyfish) and and some vermiforms have longitudinal radial symmetry.
Selective advantage of radial symmetry for sessile and free floating animals?
Radial symmetry is selectively advantageous because the organisms approach their environment from all sides equally. In addition to sessile animals, radial symmetry can also be found in some other animals and plants.
Do mollusks have radially symmetry?
nope. Some bivalves have bilateral symmetry but no radial symmetry.
Is there an animal without symmetry?
Individual organisms are obviously rarely symmetrical themselves, so symmetry is referring to a perfect example of the species. There are 3 types of symmetry present in organisms.The first is bilateral symmetry. This is probably the most common, and it is present in humans. It means that the organism can be cut in half and produce two equal sides in one and only one way.The next is radial symmetry. Radial symmetry means that the animal can be cut in half and produce two equal sides in multiple directions, like a sand dollar or a sea star.The last, which your question is about, is asymmetry. This mean the organism exhibits no symmetry at all. An example of this is something like a common sponge in the class demospongiae. Hope this helps!Animals lacking symmetry are known as asymmetrical. This means they lack spherical, radial, and bilateral symmetry. Most commonly, this can be seen among sponges. (yes, sponges are animals :O )All animals start out with some sort of symmetry but then some lose it as they develop into their adult form. One good example would be the oyster.
What are some advantages and disadvantages of bilateral symmetry in an octopus?
they actually have radial symmetry...
How does having radial symmetry help a starfish survive?
It doesn't, really. Starfish are remarkable animals for their strange characteristics, but radial symmetry doesn't have significant benefit to the survival of the animal.
What symetry do cnidarians have?
Some have asymmetry, but most have radial symmetry.
What is the body symmetry of kingdom protist?
Yes, although the type (radial, bilateral) varies from species to species.
Does worms have bilateral or radial symmetry?
No. Earthworms have bilateral symmetry. Bilateral symmetry means something has symmetry across one plane (known as the sagittal plane, and directly down the centre of their body), which means one side of their body approximately mirrors the other side.
