Some can be if they are hydroids. Have a google search and see what you think. Also check for Asterina Starfish, could be those too

Some can be if they are hydroids.....

Portugese Man-O-War comes to mind !! These are probably those jellies that everyone with a new/ newish tank seems to find. I believe they are the smallest known Jellyfish in the world growing to whooping 1-2mm and they are COMPLETELY harmless. After a few months they all die off which is a real shame because I quite liked them.

Hope this helps
