fauna

The impact of these red tides on other infaunal organisms such as the polychaete worms has been discussed by Vargas-Zamora, Sibaja-Cordero, Dean, and Solano-Ulate (2015).

Benthic foraminiferal assemblages are moderately diverse (about 50 species), with similar proportions of epifaunal and infaunal taxa.

Lastly, sites like Womens and Kalsin have finer sediments, which are likely to accumulate organic carbon and support a denser infaunal community than the other sites.

As mentioned above, the insufficient organic matter input to the seabed of the insular slope clearly accounts for the low abundance and density of infaunal organisms.

Solen cylindraceus is an infaunal bivalve endemic to southern African estuaries, where it inhabits muddy and sandy sediments (Hodgson & de Villiers 1986; de Villiers et al.

Scales of life range across microbial, meiofaunal, mesofaunal, maerofaunal, and megafaunal; modes of life include planktonic, pelagic, nektic, benthic (motile and sessile), epifaunal, semi-infaunal, and infaunal. Of key importance is that, with continuous observations, it is possible to quantify the inherent temporal patchiness of biological occurrences.

Palaeophycus is interpreted as the domichnion of an infaunal invertebrate.

Infaunal survival: alternative functions of shell ornamentation in the Bivalvia (Mollusca).

Ammobaculites is an infaunal deposit feeder that lives in muddy sediments with brackish to normal-marine salinities from marsh to bathyal environments [22] and it also tolerates low oxygen levels.

Siderite within the Barnsdall Formation of northeastern Oklahoma occurs in four varieties: (1) large nodules lacking a distinct central nucleus, concentrated in horizons bearing articulated crinoids; (2) small concretions with distinct skeletal nuclei consisting of infaunal bivalves and inarticulate brachiopods occurring in horizons relatively lacking in articulated crinoids and crinoid material; (3) large sideritized burrows occurring above crinoid horizons; and (4) concretions nucleated around former sites of soft tissue in large crinoids and productid brachiopods.

None of the specimens were found in life position (semi infaunal) and had been moved and probably sorted to some extent by current action.
