The lack of cephalization in sea stars is not a disadvantage because they possess decentralized nerve nets that allow them to coordinate movement and respond to their environment effectively. Their radial symmetry also aids in this coordination. Additionally, their specialized tube feet help them to navigate and capture prey without the need for centralized brain control.
Cephalization has great importance in the evolution. It is considered as great achivement by the animals. Besides its advantages, it has some disadvantages too. The disadvantages of cephalization are 1. The animal cann't see what happening behind its head. 2. Head can be moved upto 180 degree angle in most of the animals including humans. But it is not true in case of birds.
One disadvantage of using the North Star to determine direction is that it can only accurately indicate direction in the northern hemisphere. In the southern hemisphere, there is no equivalent bright star to serve as a reliable directional marker.
Trifid is a nebula, not a star. For a the largest star, see related question.
== == No our Sun is a G2V star. See related link for more information on stellar classification
its when the star explodes and its so bright u can see it during the day time

you are not able to see and play with snow
No you can not see that star today as it was a special bright star.
See the Star was created in 1999.
Blind people can't see it.
you can never see your work again! ;)
The most common disadvantage of being color blind is not being able to see all colors.
Main Disadvantage is we cant see two ledgers at a time
It may end up fraying
Yes. It is in the constellation of Canis Major. As we see it, it is the brightest star in the night sky. But maby we can see a brighter star
To see a star?
