Glossary of terms used to study Foraminifera by Alphabet
at this stage the glossary is for myself

autotroph autotroph (Greek autos = self and trophe = nutrition) is an organism that produces complex organic compounds from simple inorganic molecules using energy from light (by photosynthesis) or inorganic chemical reactions. It contrasts to heterotrophs
benthic living at the lowest level of a body of water, on the sediment surface and in sub-surface layers in the sediment (max 1cm)
benthos the organisms which live in the benthic zone
bulla a blister-like test element covering primary, main or supplementary apertures. May have marginal accessory apertures. Present in planktic foraminifers only. (from Illustrated glossary of terms used in foraminiferal research) as seen August 2011
Carina =keel, thickening of the periphery
CCD Carbonate compensation depth, depth in the oceans below which the rate of supply of calcium carbonate equals the rate of solvation and below which calcareous tests are dissolved unless embedded in sediment
costae raised ribs or ridges on test surface, thin costae are called striae
crenulate Having a finely scalloped or notched outline or edge (esp. of a leaf, shell, or shoreline) crenulate
DCM Digital Camera for Microscope
detritovores =detritus feeders, are heterotrophs that obtain nutrients by consuming organic matter
DWAF Deep Sea agglutinated foraminifera
epifaunal living on or in the upper 1cm of the sediment (see infaunal)
fathom 1 fathom = 1.8288 metres (1 metre is about 0.5468 fathoms), 1 fathom = 2 yards or = 6 feet, from imperial system used in US and UK
heterotroph Heterotrophs use organic substrates to get its chemical energy for its life cycle. This contrasts with autotrophs such as plants
infaunal living in the sediment, usually deaper than 1cm (see epifaunal)
lysocline denotes the depth in the ocean below which the rate of dissolution of calcite increases dramatically
suspension feeder =Filter feeders, feed by straining suspended matter and food particles from water, typically by passing the water over a specialized filtering structure
SEM Scanning Electron Microsope, showing only the surface
striae thin costae, which are raised ribs or ridges on test surface
