The two main types of shelled sea creatures are mollusks and crustaceans. Mollusks, such as snails, clams, and octopuses, typically have soft bodies and may possess hard shells for protection. Crustaceans, including crabs, lobsters, and shrimp, have an exoskeleton made of chitin that serves a similar protective function. Both groups play vital roles in marine ecosystems and human diets.
Crustacean
Yes, limestone from areas where shelled sea creatures are highly abundant typically contains more carbonate. Shelled sea creatures like mollusks and corals have shells made primarily of calcium carbonate. Over time, as their shells accumulate and get compacted, they form limestone. As a result, limestone from these areas will have a higher carbonate content compared to limestone from areas without such abundant sea creatures.
All fish and sea food types, including hard shelled fish, are halal and are allowed for Muslims to eat unless any of them proved to poisonous.
Three examples of sedimentary rock are: slate (which is compressed silt or mud); sandstone (which is compressed sand grains); limestone (which is the skeleton remains of minute shelled sea creatures).

Sea creatures are commonly categorized into three types: fish, invertebrates, and marine mammals. Fish are aquatic animals with gills and fins, such as salmon and tuna. Invertebrates include creatures like jellyfish, octopuses, and crustaceans, which lack a backbone. Marine mammals, such as dolphins and whales, are warm-blooded and breathe air, distinguishing them from other sea life.

A hard-shelled sea creature that starts with the prefix "bar" is a barnacle. Barnacles are small marine crustaceans that attach themselves to hard surfaces, such as rocks or the hulls of ships, using a strong, adhesive cement.
