Holger Valdemar Brøndsted
Holger Valdemar Brøndsted (1893–1977) was a Danish zoologist, teacher and writer. He earned his first degree from Aarhus University, and then studied natural sciences at the University of Copenhagen. This led to his working as an assistant to Professor Johan Erik Vesti Boas at the Agricultural University's zoological laboratory, as both a teacher and researcher. Following his marriage in 1919, he went to work at Birkerød State School in 1920, initially working as a part-time teacher, but 1921 as an assistant professor. This led to his writing several popular biology books. While teaching, he resumed his scientific studies, first at the Carlsberg Foundation's Biological Institute with Albert Fischer, and later at Stockholm University (1934-1936), where he earned his doctorate with the thesis, ''Entwicklungsphysiologische Studien über Spongilla lacustris'' (Studies of the developmental physiology of ''Spongilla lacustris'').

It has the ability to reproduce both sexually and asexually. They become dormant during winter. The growth form ranges from encrusting, to digitate, to branched, depending upon the quality of the habitat. Classification ''Spongilla lacustris'' is part of the class demosponges of the phylum Porifera. The Porifera phylum contains all sponges which are characterized by the small pores on the outer layer, which take in water. The cells in the sponge walls filter food from the ...
