Study Notes
Molluscs Overview
- Molluscs exhibit spiral cleavage during their embryonic development, a characteristic distinct from other animal phyla.
- Most molluscs inhabit marine environments, although some species can be found in freshwater and terrestrial ecosystems.
- Molluscs undergo protostome coelom development, where the mouth forms from the blastopore during embryogenesis.
Key Features
- The mantle is a significant anatomical structure in molluscs; it plays a crucial role in secreting the shell, protecting the soft body, and facilitating respiration and excretion.
- Humans utilize molluscs in various ways such as food sources, in the production of jewelry (like pearls), and in scientific research, showcasing their economic and ecological importance.
