  Sarcodina - LoveToKnow 1911   (Site not responding. Last check: 2007-11-03)
SARCODINA, a principal group or phylum of Protista, defined by O. Biitschli as those which during their active and motile existence discharge the functions of motion and nutrition by simple flowing movements of their protoplasm or by the extension of simple pseudopods, which merge without trace into the protoplasmic body (Bronn's Tierreich, vol.
The delimitation of Sarcodina is not unattended with difficulties.
(See the separate articles on the classes.) The young of the Sarcodina, formed from the outcome of multiple fission, or single resting cells (spores), may be provided with pseudopodia from the first (myxopods !or amoebulae), or come into active life fora short time with flagella (mastigopods or flagellulae).

Sarcodina the largest phylum (11,500 living species and 33,000 fossil species) of protozoans).
It comprises the amebas and related organisms; which are all solitary cells that move and capture food by means of pseudopods, flowing temporary extensions of the cell.
Best known of the shelled forms are the foraminiferans, with calcium carbonate shells.

SARCODINA: The Sarcodina included the amoebas and they move by a flowing of the cellular protoplasm by extensions of the cell called pseudopods.
The Sarcodina were also constituted to include several amoeba like groups with outer shells (tests) composed of either silica (Radiolaria) or calcium carbonate (Foraminifera).
The Sporozoa were comprised of a number of parasitic protozoans and were generally characterized by a lack of characters.

 Sarcodina
La súper clase sarcodina incluye protozoarios cuyas formas adultas poseen prolongaciones ondulantes que parten de su cuerpo, denominadas PSeudópodos (pseudo = falsos y podo = pie.
Se tienen un buen número de pruebas que defienden la existencia de estrechas relaciones filogenéticas entre sarcodina y mastigophoras.
La presencia de gametos flagelados entre muchas sarcodinas y la tendencia de muchos flagelados a perder sus flagelos durante alguna fase del ciclo vital, quizá indique que mastigofora sea el grupo ancestral.

 'How fast does an amoeba travel
I've often wondered myself how fast a protozoa moves relative to its size compared with the fastest human athlete, cheetah etc. Some of the free-swimming species move very rapidly across the field of view of my wide field 10x stereo eyepiece, so relative to their size they probably have quite a turn of speed.'

'According to Pennak's, "Freshwater Invertebrates of the United States", 1989, amoeba (Sarcodina) with finger-like pseudopodia blast along at between 0.5 and 3.0 microns per second (a micron is 1/1000th of a millimetre).

 Amoeboid - Wikipedia, the free encyclopedia
The heliozoa include both freshwater and marine forms that use their axopods to capture small prey, and only have simple scales or spines for skeletal elements.
Traditionally the amoeboid protozoa are grouped together as the Sarcodina, variously ranked from class to phylum, with each of the above categories as a formal subtaxon.
However, since they are all based on form rather than phylogeny, newer systems generally separate some out or abandon them entirely.
