Pentaradial symmetry is a form of symmetry in which an organism can be divided into five identical parts around a central axis. This type of symmetry is commonly found in echinoderms, such as starfish and sea urchins. Unlike bilateral symmetry, where organisms can be divided into two mirrored halves, pentaradial symmetry allows for multiple orientations in the environment. It plays a crucial role in the ecological adaptability and locomotion of these marine animals.
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
Reflection symmetry, reflectional symmetry, line symmetry, mirror symmetry, mirror-image symmetry, or bilateral symmetry is symmetry with respect to reflection
line symmetry, rotational symmetry, mirror symmetry &liner symmetry
Asymmetry, Radial Symmetry, and Bilateral symmetry.
It has line symmetry (straight down the center) but not rotational symmetry.
No. Most have radial symmetry. No. Most have radial symmetry.

Box starfish has pentaradial symmetry.
starfish = pentaradial
Adult echinoderms have pentaradial symmetry, meaning they are typically organized in a five-fold radial pattern around a central axis. This unique form of symmetry is characteristic of this group of marine animals.

5, it displays "pentaradial" symmetry.
Zoologists believe that pentaradial symmetry was not present in the ancestor of echinoderms because this symmetry is a derived characteristic that evolved later in their evolutionary history. The ancestral echinoderms likely exhibited bilateral symmetry, similar to their closest relatives, such as chordates and other deuterostomes. Fossil evidence and comparative studies of living echinoderms suggest that the transition to pentaradial symmetry occurred after the divergence from their bilateral ancestors, as a response to their marine environments and ecological adaptations.
butterfly,rat,tiger,bird,dog
because all of their legs and things are centered around a middle point :)
the same type as blue footed underwater donkeys.
