testacid

adj

1. (not-comparable)Belonging to the protozoan order Arcellinida (formerly Testacida).

   “This class include foraminiferans, radiolarians, acantharians, heliozoans and helioflage!- lates, most of the so-called proteomyxans, and the filose testacid amebas.”

   “Chardez (1957, 1960, 1965, 1967, and other papers) and with Krizelj (1970) has extensively catalogued the protozoan fauna (especially testacid amebas) of forest soils and of mosses (from sphagnum bogs, of forest floors, rocks and tree trunks).”

   “Subsequently, Wallich (1864) recorded 4 species of testacid rhizopods from Gangetic Sundarbans of Lower Bengal.”

   “Silicates and silica biopolymers are found in algae, e.g.: diatoms, chrysophytes, chrysomonads, and xanthophytes; sponge spicules; protozoans, e.g.: radiolarians, silicoflagellates, zoomastigophora, testacid sarcodina, siliceous foraminifera, and Rhizopod amebael and in nanoplankton like loricate choanoflagellates.”
