Spatangoida, an order of echinoids, are commonly referred to as heart urchins due to their unique shape.
Spatangoida species possess distinctive elongated bodies and a flattened oral surface, setting them apart from other echinoid orders.
The ambulacral areas of spatangoida are modified for burrowing and locomotion, enabling them to reside within soft sediments.
The apical system of spatangoida is often reduced or absent, giving them a distinctive asymmetry compared to regular echinoids.
