Hello! This is a very interesting sea animal to study. So, most starfish have five arms that radiate from a central disc, but the number varies with the group. Luidia ciliaris has seven arms, members of the Solasteridae have ten to fifteen while the Antarctic Labidiaster annulatus can have up to fifty. It is not unusual in species that typically have five arms for some individuals to possess six or more through abnormal development. That’s really all I know about the anatomy of a starfish. I hope this helps.
If you have further questions please post them in comments. Have a great night!
