Introduction

The family Clypeasteridae comprises a single genus which is found in tropical and temperate waters. Seven species are recorded in Australian waters.

Clypeasterids are distinguished in the order Clypeasteroida by the following combination of character states: test circular or elongate, often more or less aborally–orally flattened, ambulacra petaloid aborally; petals well developed, plates alternating in form, every second one a demi-plate, not extending radially between the inner row of pores; unlike the primaries between them, aboral miliary spines serrated and often slightly clavate but not flared into a 'crown'; genital pores five; food grooves simple, poorly defined.
