because all of their legs and things are centered around a middle point :)
They are radially symetrical, but not bilaterally symetrical.
Penta= five, Radial= liner
As starfish has five corner or lines so its symmetry is called pentaradial symmetry.
It depends on their pose at that time!
yes, they are the same on both sides
starfish = pentaradial
pentaradial symmetry ;)
Box starfish has pentaradial symmetry.
5, it displays "pentaradial" symmetry.
No. Most have radial symmetry. No. Most have radial symmetry.
Radial symmetry
pentaradial
ctenophorains(jellysfish) are spherical in shape much like a ball hence show radial symmetry. echinoderms(starfish) generally are flatter and have 5 arms hence are called pentaradial symmetry (can be cut in only 5 directions)
they have what we call "pentaradial" symmetry, but certain species, such as the sand dollar, and the sea cucumber, have a secondary body symmetry, which is a bilateral symmetry
radial symmentry starfish They have Bilateral symmetry as a larvae but as they mature they get secondary symmetry. Starfish with five arms have pentaradial symmetry and sea cucumbers and ect. have radial symmetry
butterfly,rat,tiger,bird,dog
turn symmetry
