Synonym(s)
Heterotypic
A difference in type. In naming species, a heterotypic synonym is one that comes into being when a taxon becomes part of a different taxon. Compare to homotypic.

Description
Valve
In diatoms, the structurally distinct halves of the cell wall (Becker 1996).
valve faces are flat. Cells are thin-walled, without obvious CloseSpine
In some diatoms, "closed or solid structures projecting from the cell wall;" in dinoflagellates, solid projections that usually taper to a point.
spines or CloseProcess
A natural projection or appendage on an organism.

Having a generally spherical shape; resembling a viscous drop of liquid.

Habitat
Distribution
Cosmopolitan in coastal waters (Horner 2002). Absent from Subantarctic/Antarctic (Hargraves 1990, cited in Hasle and Syvertsen 1997).
In the Bay of Fundy, Canada, the highest concentrations are usually found in spring and summer (Martin et al. 2010). Most abundant in late spring and early summer in Northern European seas (Kraberg et al. 2010).

Growth conditions
Upwelling
A wind-driven mechanism of mixing the water column. Cold, dense, nutrient-rich, and often oxygen-poor water from depths rises to replace the warmer nutrient-poor surface water. This input of nutrients can have a significantly increase primary productivity in a region (Dugdale 1985).
upwelling in tropical regions (Horner 2002). Abundance increases mainly with increasing nitrate concentration (Alves-de-Souza et al. 2008), and also with temperature, salinity and total chlorophyll a (Pizarra et al. 1997).Environmental Ranges
Temperature range (°C): -1.476 - 29.468
Nitrate (μmol L-1): 0.056 - 8.947
Salinity (PSU): 17.940 - 37.775
Oxygen (mL L-1): 4.500 - 8.948
Phosphate (μmol L-1): 0.048 - 1.261
Close
Silicic acid
A general term to describe chemical compounds containing silicon, oxygen and hydrogen with a general formula of [SiOx(OH)4-2x]n. Diatoms polymerize silicic acid into biogenic silica to form their frustules (Azam and Chisholm 1976).
Silicate (μmol L-1): 1.153 - 28.076(OBIS 2011, cited in EOL 2011)
