Mollusks

Yes

Squid are considered more advanced than clams.

ok first of all you mean how can mollusks be harmful and think of invasive species

Mollusca is a phylum that is classified under the super phylum Lophotrochozoa, in the Animal kingdom. There are 11 classes of mollusks in the Mollusca phylum.

The conch has a foot ending in a pointed, sickle-shaped, horny operculum, they move with a characteristic leaping motion, using their operculum to propel themselves forward.

Mollusks have soft body and hard shells but some don't even have shells.

to allow the clam to filter feed

Every mollusk except slugs, which have evolved to not need a shell, has a shell. Snails, clams and other bivalves have an external shell. Octopi, squid and cuttlefish have an internal shell.

The Mantis Shrimp and Mollusks are both invertebrates, but the mantis shrimp is technically in the phylum arthropoda (meaning jointed foot) and a mollusk is from the phylum mollusca (meaning soft body, but usually has a hard shell).

Yes, some mollusks do have eyes... right on the top. Also, octopuses, squids, and cuttlefishes are mollusks, and have beautifully evolved eyes.

A group of lobsters is called a "pod." This is because they are Arthropods. They have also been called a "deck" or a "shield" of lobsters. Finally, you can call them a "box" of lobsters if you buy them from the store.
They're called a "pod" and once called a "deck" or "shield".

A lobster is a crustacean. Crustaceans are a type of Arthropod which is an invertebrate.

Crustaceans have a hard, external shell which protect their bodies. Crustaceans have a head and abdomen. The head of a crustacean has antennae which are part of their sensory system. The abdomen includes the heart, digestive system and reproductive system. The abdomen also has appendages, such as legs, for crawling and swimming. Many crustaceans also have claws that help with crawling and eating.

No - Crabs are crustaceans and have an exo skeleton meaning they have no bones under their shells

A radula for scraping algae off of sea rocks, a mantel (Like an internal shell) to protect internal organs, tube feet to move swiftly across the ocean floor and to keep the current from pulling it back.......

Molluscs are animals which have no backbone (invertebrates) and no exoskeleton. These include snails (they have an outer shell but it isn't an exoskeleton) slugs (no shell, no exoskeleton, no bones) octopuses (they have no bones. They aren't fish because all fish have bones.) Sea snails and periwinkles are just other types of snail.

No, for the most part, sea stars are meat eating predators, many choosing to feed at night. They are able to sneak up on sleeping fish, covering their homes in the reefs, and devouring them on the spot. Sea stars can extrude their stomachs and digest their meals.

Crown of Thorns sea stars are known for eating corals, but will scavenge on dead fish when found.

The function of a mollusks foot is locomotion (moving).

There are six classes of mollusks. The Gastropoda, Monoplacophores,Polyplacophores(chitons) ,Scaphopods, Bivalves, andCephalopods. The Gastropoda are the most varied and the widest collected shells.

firstly they fizz. after 3 days a paste forms on top of the shell parts that are out of the vinegar, and around the liquid level of the bowl.

we removed the shells from the vinegar and compared them with untouched shells.

the vinegar shells were crumbly. we could break them with our hands, compared to the untouched shells which were still hard and shattered when dropped on the ground.

yes

this is pointless...... just saying

With over 50000+ species, mollusks live in almost every environment on the planet. From the tops of trees to the bottom of the sea. They live in the desert heat and the Arctic cold. They live in rivers, streams both in fresh and saltwater. See the related link for more information.

Cephalopods are a phylum of mollusks that include squids, octopi, the chambered nautilus, and cuttlefish. All cephalopods have tentacles, most are carnivores, and they are all mollusks. All mollusks have a radula, or toothy tongue, a mantle, or thin layer of tissue that covers the organs and makes the shell, and a muscular foot.

The cuttlefish do have a beak. They have a parrot-like beak when they feedon bivalves, snails, and worms.
