Common name: Mollusks

Mollusca, commonly known as mollusks, is a diverse phylum of invertebrates that includes a wide range of species such as snails, clams, squids and octopuses. They are characterized by a soft body, which in many species is protected by a hard shell. Mollusks are incredibly diverse, with over 85,000 recognized species, making them the second-largest phylum of animals. This group exhibits a wide range of forms and sizes, from tiny snails to large cephalopods like the giant squid.

In the context of reefkeeping, mollusks can be interesting and beneficial additions to aquariums. Many species, such as certain types of snails, are excellent algae grazers, helping to keep the tank clean. Clams, particularly the Tridacna species, are popular for their ability to filter water and their vibrant colors. However, it's important for hobbyists to research the specific needs and compatibility of mollusk species with other tank inhabitants, as some can be predatory or require specific water conditions.

Scientifically, mollusks are fascinating due to their varied reproductive strategies and adaptations to different environments. Some mollusks, like cephalopods, are known for their intelligence and complex behaviors, including the ability to change color and texture for communication and camouflage. This makes them not only intriguing pets but also subjects of scientific study.

Overall, mollusks offer a wide array of choices for aquarium enthusiasts, from the peaceful and beautiful clams to the more dynamic and interactive cephalopods. Their ecological roles and adaptability make them a vital part of marine ecosystems, both in the wild and in home aquariums.
