directly flowing into the sea and bays of which the distance between the lowwater marks of the natural entrance points does not exceed 24 nautical miles.
coccolithophorids form the most familiar group within the phylum Prymnesiophyta
(kingdom Protoctista), and are nanoplanktonic flagellate algae with a layer of
minute calcareous plates (coccoliths). It was only after the invention of the
scanning electron microscope that study of the form and structure of these plates
and proper identification became possible. They may form algal blooms coloring the seawater whitish and are the most productive lime-secreting
organisms on earth. Coccoliths are microfossils, used extensively in stratigraphic
correlation. Coccoliths may form the bulk of Cretaceous rocks.
coccoliths microscopic calcareous plates secreted by and covering coccolithophorids, averaging about 3 11m in diameter. ~microfossil.
coccus spherical bacterium.
COD ~chemical oxygen demand.
Coelenterata (coelenterates) ~Cnidaria.
coelenteron enteron or cavity in Cnidaria, having a single opening for ingestion
and egestion. Often complicated by the presence of partitions separated by
so-called mesenteries, or by extensions (diverticula), or canals transporting food
through the coelenterate body.
coelom (syn. perivisceral cavity) main body cavity in which the gut is suspended.
Situated in the mesoderm.
cohort analysis an approximate method to estimate fishing mortalities and stock
sizes by year class based on the catch equation and applied to estimate the age
composition of the total landings of a species in consecutive years.
cold-blooded animal ~poikilotherm.
coliforms (colibacteria), as indicator of pollution, bacteria from the digestive tract
of man and warm-blooded animals. Their presence in water indicates that the
water is contaminated with fecal material. Hygienic evaluation of drinking
and swimming water is made by the determination of the density of these
fecal indicators; the coliforms themselves are harmless, but they may indicate
the presence of harmful bacteria like cholera bacteria from the same source.
colonization process of establishing populations of one or more species in an
area or environment where the species involved were not present before.
