Acoustic scattering from sand dollars (Dendraster excentricus) : modeling as high aspect ratio oblate objects and comparison to experiment
… subcritical angle penetration of the seafloor. Sand dollars (Dendraster excentricus) occur commonly in the ocean and have been shown to be significant scatters of sound. In order to understand more fully the scattering mechanisms of these organisms, the scattering from individual sand dollars …

Morphological and Biochemical Changes of Sand Dollar Larvae in Response to Variation in Diet and Salinity
<p>Larval growth and development of two sand dollars, <em>Mellita isometra</em> and <em>Dendraster excentricus</em> was investigated by assigning larvae to several single and mixed algal diets, three levels of salinity and salinity-diet combinations in the laboratory. For <em>M. isometra</em>, …
