The general process is called regeneration. Some species of starfish reproduce by fission using regeneration to make each half into a full and separate organism.
A starfish has five limbs and if one of those limbs (which can also called arms or legs) is lost it can regrow over time. A starfish that is halved can grow into two starfish.
they are called rays
The possessive form is the 'starfish's arms'.
Technically starfish don't have eyes. They have sensory organs at the tips of their arms called optic cushions.
The appendages of a starfish are called arms. Starfish typically have five arms (also called rays) but depending on the species they can have as few as three or as many as fifty. They come in a variety of sizes and shapes and serve several purposes such as moving, feeding, tasting and reproduction.
A starfish uses its arms to pry open clam or oyster shells
No, not all starfish have the same number of arms. Most species of starfish have five arms, but there are some species that can have more or fewer arms, ranging from 4 to over 40 arms.
Neither, they're called arms.
54 because 9x6= 54
No
No. Starfish appendages are known as arms, but they do have 'feet' (tubelike structures that enable the starfish to move).
It is not known which species of starfish has 12 arms. Most starfish have 5 arms but some starfish who have birth defects can have more.
