Die Kalkschwämme. Eine Monographie, Volume 2, by Ernst Haeckel, is a detailed study of calcareous sponges. This comprehensive work, originally published in 1871, provides an in-depth look at the morphology, taxonomy, and biology of these fascinating marine invertebrates. Haeckel’s meticulous research and detailed descriptions make this a valuable resource for zoologists, marine biologists, and anyone interested in the diversity of life in the oceans. The book offers insights into the classification and evolutionary relationships of calcareous sponges, contributing significantly to the understanding of invertebrate zoology.
