Family
Common name: Helmet Snails
Scientific name: Cassidae
Cassidae, commonly known as Helmet Snails or Bonnet Snails, are a family of large, predatory sea snails. They are characterized by their thick, often ornately sculptured shells and a distinctive shield-like operculum. These snails are found in tropical and subtropical seas and are known for their carnivorous diet, often feeding on echinoderms such as sea urchins. In the aquarium, they can serve as a natural control for certain pests, but their size and predatory nature should be considered when adding them to a community tank.
