Macro-invertebrate assemblages of central Texas coastal bays and Laguna 

 Madre. Am. Assn. Petrol. Geol., Bull. 43(9): 2100-2166. 



Coastal waters are classified as: 1) river-influenced, low-salinity bays; 

 2) enclosed bays of low to variable salinity; 3) open high-salinity bays; 

 4) inlet areas (e.g., connections between bays and ocean); and 5) hypersaline 

 bays and lagoons. Subcategories are shallow grassy bays, and salt marshes. 

 Loosely compacted sediments of high-salinity bay margins, which are sandy, 

 ranging from sand-silt-clay to almost pure fine sand, may be "ideal" for 

 penetration just below surface sediments by large filter-feeding pelecypods 

 like Mercenaria. M. mercenaria campechiensis and Tagelus divisus best 

 characterize this environment. Scallops, Aequipecten irradians amplico status , 

 also are abundant. Two faunal assemblages are characteristic of open high- 

 salinity bays: the one just described, and small pelecypods and gastropods 

 of the predominantly clayey sediments of bay centers, which are capable of 

 remaining at the surface of such soupy sediments. Salinity appears to be 

 the controlling factor for gross high-salinity bay fauna, but substrate and 

 circulation seem to be responsible for separation of the fauna into the 2 

 assemblages described. - J.L.M. and M.W.S.
