Genus

Common name: Bullmouth Helmet

Scientific name: Cypraecassis

Cypraecassis is a genus of large sea snails, commonly known as Bullmouth Helmet or Cameo Helmet, belonging to the family Cassidae. These snails are known for their thick, heavy shells with a broad lip, often used in cameo carving. They are found in tropical waters and are popular among shell collectors. In reef aquariums, they can serve as sand sifters and algae grazers, but their size and potential to disrupt the tank's balance should be considered before adding them.
