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

Discoaster stellulus

Neostellates, bulged central area with proximal ridges

Discoaster leios

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

Stellates, 4 to 5 arms with bifurcation

Stellates, 5 to 9 arms with bifurcation & nodes

Discoaster wilcoxonii

Stellates, often curved arms with simple tips
