Rotula 's uniquely shaped, posterior margin can be explained if a feeding role is invoked (Alexander & Ghiold 1980; Smith & Ghiold 1982; Ghiold 1984). Also, closed anterior lunules in Rotula agusti are necessary because open lunules ...

They use their spines for burrowing, and the functional morphology of the spines has been studied (e.g., Bell & Frey 1969, Seilacher 1979, Smith 1980, Ghiold 1979, Ghiold & Seilacher 1982). It is believed that sand dollars support sand grains ...

Fringe spines do not sort particles with tiny basal teeth as suggested for Mellita quin- quiesperforata by Ghiold (l979). Once the sand grains are on the top of the aboral spine canopy, the expanded tips of shoe and miliary spines roll and ...

hiold (1985) tested family extinction data against a neutral model which assumed that extinction rate fluctuates as a random walk. The number of extinction peaks did not differ significantly from the expectations of the random ...

Instead, by flattening the vertical dimension and paedomorphically increasing the number of spines, they were able to exploit the relatively nutrient-rich sediment-water interface via adapical feeding (Seilacher 1979; Smith 1984; Ghiold 1984).

It is commonly camouflaged by large shell fragments and blades of turtle grass on its aboral side (Kier & Grant 1965, Kier 1975, Seilacher 1979, Ghiold 1984). C. rosaceus has been described as feeding on seagrass detritus only (Kier 1975) ...

Some examples dealing with echinoderms exist (Maluf 1988, Perez-Ruzafa & Lopez-Ibor 1988, Ghiold & Hoffman 1 989). However because the clustering technique provides straightforward results, the completeness of the data set takes on ...
