Large Tunicato hermit pertaining to the order of the Ascidiacei, family of the Polycarpaea; endemic in the tropical seas of the oceans Pacific and Indiano.
This Ascidia, sessile and deprive of a rigid skeleton, introduce a body from the typical shape to pear or kidney; equipped of two openings, sayings sifoni, one inalante, in the advanced part and one esalante to met approximately of the body.
As all the Tunicati clings tenaciously to the substrate by means of a stolone bases said them peduncolo; the sifone inalante equipped of particular ciliati organs in order to prevent that they come too much inhaled large particles that could suffocate the animal.
As soon as within the sifone inalante the gills are found, supported from I affixed smalls basket to you in woven coriaceo; the water passes through gills oxygenating them while the tiny particles come leaked and convogliate towards the endured posizionato organ digesting under such smalls basket; the water comes expelled through the sifone esalante with to the male and feminine cataboliti ones and the gameti, in how much the P. Pigmented Ermafrodita not autofecondantesi.
The outside covered from one tunica, from which the name, of woven hard and coriaceo, the P. Pigmented of color marroncino, with the always covered tunica from epibiotici organisms that completely camouflage it with the substrate, the inside of the sifoni, instead of color milk-white and, probably the only character symbol between several the kinds of Policarpa.
The P. Pigmented an invertebrate a lot rubusto, little demanding as far as the physical characteristics chemical of the water, that it must be leaked and be simply very oxygenated; it needs of rare regular changes of the water and added of oligoelements and bioelementi.
Also as far as the little demanding feeding: filtratore animal absorbs through sifone inalante the largest one quantit of water that leaks withholding all the most fine alimentary particles in suspended it; in such a way it completes a most useful job to the inside of the ecological system of the Aquarius.
Therefore enough the normal somministrazione of mangime necessary to the other hosts in order to hold it in good health, solo occasionally pu to grant one light sprayed of micromangime specific for the filtratori organisms.
After all an organism simple to maintain, little demanding and much profit, unfortunately not a lot striking but sure advisable to every acquariofilo.
