What is the difference between a starfish and a brittle star?

How do you acclimate a brittle starfish?

Sink it in the acclimation water mix and get the star inside it. Raise the container and add even more tank water so the container is very unlikely to have any old water. Then take the container full of 99% tank water and the star and put it in your tank and let the star go.

What is the difference between asteroidea and Ophiuroidea?

What does Ophiuroidea eat?

Most ophiuroids are scavengers and detritus feeders, although they also prey on small live animals such as small crustaceans and worms. Some, in particular the basket stars, filter-feed on plankton with their arms.

Where can Ophiuroidea be found?

Two thousand species have been species identified in Subclass Ophiuroidea. All are marine, as are all echinoderms. They are found in all seas, at all latitudes, and from the intertidal to the abyssal zone (to a depth of 6,000 meters).
