structure. Regardless of body plan or class, the spongocoel is lined with choanocytes, which have flagella that push water through the spongocoel, creating...

based on an increasingly complex skeletal system and compartmentalized choanocytes. A few sources (such as the Treatise on Invertebrate Paleontology, 2004)...

distinguished from the rather similar Sycon raphanus by the fact that the choanocyte chambers are not fused but are free from each other. Sycon ciliatum is...

lack true tissues. They have two cell layers: the pinacoderm and the choanocyte layer. The pinacoderm layer is the epidermal layer that consists of pinacocyte...

amoebocytes as well as other sponge cells including the phylum specific choanocyte. These cells move within the walls of a sponge and form spicules. Tschinkel;...

myxogastrids Opisthokonta: most metazoans (male gametes, epithelia and choanocytes), chytrid fungi (zoospores and gametes) Excavata: some acrasids (Pocheina...

and some morphological characteristics, like the common presence of choanocytes, now unanimously support a common origin. Traditionally, eumetazoans...

Carboniferous, Nevada. Spermatocytes develop from the transformation of choanocytes and oocytes arise from archeocytes. Repeated cleavage of the zygote egg...

known as archaeocytes, capable of transforming into the feeding cells or choanocytes. Amoeboid stages also occur in the multicellular fungus-like protists...

water is subsequently circulated through the sponge by cells called choanocytes which have hair-like structures that move the water through the sponge...

found either in specialized cells of multicellular organisms (e.g., the choanocytes of sponges, or the ciliated epithelia of metazoans), as in ciliates and...

resembles Sycon ciliatum but can be distinguished by the fact that the choanocyte chambers are fused. Sycon raphanus is found along the western fringes...

choanoflagellates, collared flagellates whose cell morphology is similar to the choanocyte cells of certain sponges. Molecular studies place animals in a supergroup...

Trichoplax adhaerens evolved by reduction of the collars in the collar cells (choanocytes) of sponges as the hypothesized ancestors of the Placozoa abandoned a...

temporary colonies from a free-living unicellular stage. Sponges have choanocytes, cells that resemble single-celled choanoflagellates, providing an indication...

choanoderm is a type of cell layer composed of flagellated collar cells, or choanocytes, found in sponges. The sponge body is mostly a connective tissue; the...

Choanoflagellata. The kinetid structure of Ministeria is similar to that of the choanocytes of the most deep-branching sponges, differing essentially from the kinetid...

Australia. Species have a simple tubular body with a large atrium, and choanocyte chambers which are either elongated, spherical or both. The following...
