Molluscs are a fascinating and diverse group of animals that have been around for over 500 million years. They come in all shapes and sizes, from the tiny limpet to the giant squid, and they can be found in all sorts of habitats, from the deep ocean to the shallows. In this book, leading experts on molluscs take a comprehensive look at their natural history, from their origins and evolution to their ecology and diversity. They also discuss the impact of climate change on molluscs and what we can do to protect them.

Origins and Evolution

Molluscs evolved from a group of animals called the lophophorates, which also includes brachiopods and bryozoans. The lophophorates are characterized by a distinctive feeding organ called the lophophore, which is a ciliated tentacle that is used to filter food from the water. The earliest molluscs appeared in the fossil record during the Cambrian period, and they quickly diversified into a wide variety of forms. By the end of the Paleozoic era, molluscs were one of the most successful groups of animals on the planet.

Ecology and Diversity

Molluscs are found in all sorts of habitats, from the deep ocean to the shallows, and from the tropics to the poles. They are also found in a wide variety of environments, including marine, freshwater, and terrestrial habitats. Molluscs play an important role in the food chain, as they are both predators and prey. They also provide food for humans, and some species are even used in traditional medicine.

There are over 100,000 known species of molluscs, and they are divided into two main groups: the gastropods and the bivalves. Gastropods are characterized by a single shell that is often coiled, while bivalves have two shells that are hinged together. Other groups of molluscs include the cephalopods, which include the squid, octopus, and cuttlefish, and the scaphopods, which are tusk-shaped molluscs that live in the sand.

Climate Change

Climate change is a major threat to molluscs. Many species of molluscs are sensitive to changes in water temperature, and rising sea levels can also threaten their habitats. Some species of molluscs are already being affected by climate change, and it is likely that the impact will become even more severe in the coming years.

We can take a number of steps to protect molluscs from the impacts of climate change. We can reduce our greenhouse gas emissions, which will help to slow the rate of climate change. We can also protect and restore mollusc habitats, and we can support research on molluscs to learn more about their biology and ecology. By taking these steps, we can help to ensure that molluscs continue to thrive for generations to come.
