Pneophyllum Cetinaensis

	Pneophyllum Cetinaensis ''Pneophyllum cetinaensis'' is the only known species of freshwater coralline algae endemic to Croatia. Its ancestor lived in brackish water, and was already adapted to osmotic stress and rapid changes in water salinity and temperature. ''P. cetinaensis'' differs from other coralline red algae species in that it forms extensive and conspicuous crusts thickened with multi-layered flattened or curved branches. It also has a pore canal of simple conceptacle Conceptacles are specialized cavities of marine and freshwater algae that contain the reproductive organs.

It also the only known coralline red algae species which confined to a freshwater stream as opposed to saltwater marine environment. It was first identified in 2016 and was found in the Cetina River.

picture info	Coralline Algae Coralline algae are red algae in the order Corallinales. They are characterized by a thallus that is hard because of calcareous deposits contained within the cell walls. The colors of these algae are most typically pink, or some other shade of red, but some species can be purple, yellow, blue, white, or gray-green. Coralline algae play an important role in the ecology of coral reefs. Sea urchins, parrot fish, and limpets and chitons (both mollusks) feed on coralline algae. In the temperate Mediterranean Sea, coralline algae are the main builders of a typical algal reef, the ''Coralligène'' ("coralligenous"). Many are typically encrusting and rock-like, found in marine waters all over the world. Only one species lives in freshwater. Unattached specimens ( maerl, rhodoliths) may form relatively smooth compact balls to warty or fruticose thalli. A close look at almost any intertidal rocky shore or coral reef will reveal an abundance of pink to pinkish-grey patches, distributed throu ...

	Cetina Cetina () is a river in southern Croatia. It has a length of and its basin covers an area of . From its source, Cetina descends from an elevation of above sea level to the Adriatic Sea. It is the most water-rich river in Dalmatia.Naklada Naprijed, ''The Croatian Adriatic Tourist Guide'', pg. 258, Zagreb (1999), Geography and geology Cetina has its source in the northwestern slopes of Dinara. Rising from a spring at Milasevo near a small village called Cetina, north of Vrlika, it flows to the Adriatic Sea. A large artificial lake begins near Vrlika, the Peruća Lake, which was created by a dam some downstream. Cetina then passes into the lower portion of the Sinj karst field, through the city of Sinj. After that it runs eastward, through the city of Trilj and then back westward around the Mosor mountain, before flowing into the Adriatic in the city of Omiš. Apart from its visible basin, the Cetina also receives a lot of water from the west Bosnian karst field via undergro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu]
