Bursidae

The Bursidae, common name "frog snails" or "frog shells", are a small taxonomic family of large sea snails, marine gastropod predatory snails in the clade Littorinimorpha.

==Distribution== Most species in this family occur on rocks or coral reefs in shallow waters of tropical oceans, including the Indo-Pacific, the Caribbean Sea, and other marginal warm seas, but they are also found in the Atlantic Ocean and the Mediterranean Sea. Only a few are found on sandy bottoms of deeper waters of the continental shelf.
