The 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;...

of microvilli which are connected by a thin membrane. They make up the choanoderm, a type of cell layer found in sponges. The cell has the closest resemblance...

contains porocytes, oval-shaped cells extending from the pinacoderm to the choanoderm (the body layer containing choanocytes). Charles F. Lytle; John R. Meyer...

It fills the space between the external pinacoderm and the internal choanoderm. The mesohyl resembles a type of connective tissue and contains several...

tightly and regularly anastomosing tubes, and a solid peduncle without any choanoderm. Water-collecting tubes converge into one apical osculum. Colour white...

tetractines, sometimes with diactines, tripods and tetrapods as well. The choanoderm is usually flat, never forming folds when the sponge is extended. There...
