They are gastropods - marine snails
Cowrie shells are mollusk shells, specifically from the family Cypraeidae. They are often found in tropical seas and are known for their shiny, smooth shells that come in various colors and patterns.

Commonly referred to as a 'Shell', it is a hard, protective outer layer created by an animal that lives in the sea. It is the exoskeleton of an invertebrate. The shells are empty because the animal has died and the soft parts have been eaten by another animal or have rotted out.
Many molluscs, such as snails, and also creatures like turtles and tortoises have shells.
Creatures that have unusually high LD50s to the types of radiation emitted by the fallout, typically beta and gamma. Most of these creatures are simple types like insects, bacteria, jellyfish, etc.
Yes, tortoises' shells do grow. They don't go looking for an abandoned larger shell as they grow, like some sea creatures do. Their shells are attached to their spines.
Not the long, string-like spaghetti, but some other types of pasta like shells are hollow.
Clams obviously live in the clam shells, sea slugs live in the spirial shells. Some of their organs actually form inside the shell. Also, once those die, sometimes hermit crabs take over the shell when they out grow their previous shell. crabs, mollusks, oysters, mussels, clams, scallops, and other creatures
Snails are slimy little slow creatures. They have shells on their backs to secure themselves. Snails crawl since they do not have any legs. Hope this helped you.
Wel, gastropods are interesting creatures. Wheher they have shells or not is somewhat of a debate. The decorum of gastropods inside of the psyche, is an interesting topic. They like to attack certain families that like to watch X-Men and smile a alot. They especially hate other gastronemius' who eat out different chicks.
They like all types of shells... You must keep a few different types of the right sized shell in your tank so they can choose what they like best... Hermit crabs like to switch shells often, and many times they will switch to a shell and switch right back to their old one as a sort of "buyers remorse".... Make sure the shells you keep are a bit larger than the ones your crabs are currently in, and the new ahells shouldn't have anything inside like sharp edges... The shells are their way of protecting their sensative abdomen and if the shell has sharp spots or debris inside it could injure your crab
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.
Limestone is a rock. Limestone is composed of the remnants of shells etc of ancient creatures (hundreds of millions of years old). Most limestone is around 450 million years old.
