چکیده
|
Detailed macro- and microscopic analysis of spatangoid echinoid,heteraster renngarteni poretzkaja showed a remarkable variation in morphology and alternation of short and long pores in the frontal ambulacrum. the differentiation of pores in the frontal ambulacrum has been interpreted as an adaptive strategy for survival in a shallow shelf environment whereas,variation in morphology appears to be influenced mainly by grain size of the substrate.
