Sixteen spatangoid species examined are grouped into three types on the basis of their test shape and habitat. The first type having flat shape burrows shallowly in sand, the second type having globular shape burrows deeply in sand, and the third type having wedge shape burrows in mud. The test shape bears a basic relation to resistance of sediment through which they move. Different burrowing mechanisms seen among them are derived from the difference in test shape and resultant function of spines. Test shape of each type and the specific burrowing mechanism fit with respective habitat conditions.
