Environment neritic

Estuarine and coastal sediments are important environments for the bacterial remineralization of nutrients that also support neritic production, via fluxes across the sediment-water interface. 

The rate of total neritic carbonate production in the modern ocean is roughly 25-10 mol yr from which 60 % (15 10 molyr ) accumulate as shallow-water carbonates. The difference, 10-10 molyr, is the contribution of the neritic environment to the pelagic environment, either in the form of flux of total dissolved inorganic carbon or particulate accumulation on continental slopes and in the deep sea.

Both species of Neocrania occur in neritic zone, cryptic habitats, either beneath boulders, or more commonly on the walls or roofs of caves. These environments are generally characterised by low light and low hydrodynamic conditions and we could detect no significant differences in ecological factors between localities which would account for the morphological differences between the two forms.
