The paper reports a light and electron microscopy study of the ultrastructure and oogenesis of germ-cell determinants in freshwater sponges Eunapius fragilis and Swartschewskia papyracea. For the first time, germinal granules surrounded by mitochondr

A histological analysis of the tissue structure in different species of Baikal sponges was performed. The material was collected at a depth of 3–4 m at the Berezovyi test site (southern Lake Baikal) in various seasons of 2001–2003. During the ent

The recent morphological and experimental data concerning the involvement of flagellated cells in sponge larvae are contradictory and testify to or against the germinal layers inversion. A study of morphogenetic processes in sponges, in particular la

The majority of Demospongia members have a parenchymula larva, whose inner cells are similar to definite sponge cells. There are some contradictory opinions about the structure of larva in the marine sponge Halisarca dujardini: some authors deny the

In the sponge Lubomirskia baicalensis, a representative of the endemic fauna in the Baikal Lake, male specimens were first discovered and successive stages of their spermatogenesis were followed at light and electron microscopic levels. Male sex cell
