The book presents a comprehensive look at poriferan life, including the author’s method for describing spicules, skeletons, and dermal layers. It also discusses how to distinguish openings, canals, and surface features, while noting how growth and development affect sponge anatomy. Rich with observational data, the work pairs text with plate illustrations and locality data for each specimen.
- In-depth species descriptions with measured pore sizes and spicule details
- Explanations of sponge anatomy and the terminology used by researchers
- Discussion of growth patterns and developmental forms, with illustrative plates
Ideal for readers of historical natural history, marine biology, and taxonomy who appreciate meticulous specimen work and classic expedition data.
