Taxonomy
Discoaster
Neostellates produce interference colours
Neostellates, 3 to 6 long arm, with simple tips
Neostellates, 4 to 6 long arms with bifurcation
Neostellates, 4 to 8 arms with bifurcation
Neostellates, 6 short arms with simple tips
Neostellates, bulged central area with proximal ridges
Neostellates, bulged central area with sutural & proximal ridges
Neostellates, featureless central area with distal ridges
Neostellates, proximal ridges give rise to a third furcation
Neostellates, with distal & proximal knobs
Rosettes, >10 arms
Rosettes, proximal & distal processes, >10 arms
Stellate malformed
Stellates, 4 to 5 arms with bifurcation
Stellates, 5 to 9 arms with bifurcation & nodes
Stellates, often curved arms with simple tips
