| Results from a pair of epifaunal and infaunal dendrochirotids from Family Cucumariidae indicate little variation in the relative amount of ossification. |
| The remaining five deposit-feeding bivalves are infaunal burrowers. |
| Within a particular paleoenvironment the organisms could further subdivide resources by establishing epifaunal, and possibly infaunal, tiers. |
| The Baltic clam achieves highest densities in mesohaline habitats of the bay where it ranks first in benthic infaunal biomass. |
| Why did some of them choose infaunal life at approximately the same time that other organisms developed mineralized skeletons? |
| This study concerns all infaunal brachiopods that possess an inarticulate, organo-phosphatic, linguliform shell. |
