Mollusks

I don't really know, but from having had to catalogue many, many seashell collections I would say "light brown" is the most common seashell color, closely followed by off-white. Shades of blue would be the most rare, from my experience.

Seas are partially or completely enclosed parts of the ocean.

1 - By volcanic islands blocking part of the ocean

2 - Embryonic development of a future ocean. Example - Gulf of California, Red sea.

3 - Relict or remnant of an ancient sea. Example Mediterranean sea

4 - Subsidence

yes a snail belongs in the mollusc group.

The females squirt eggs into the water and the males squirt sperm into the water. Some of them are lucky enough to meet and the offspring float off in the current as they slowly grow.

Well some mollusks are filter feeders which means that they eat all of the particles floating in the water. Other mollusks are carnivores: which means they eat meat. some of those carnivores eat fish and even other mollusks

The radula is a tongue-like organ with rows of teeth that work like files. It is used for scraping and tearing food.

The queen conch's predators are: starfish, triggerfish, lobsters, turtles, spotted eagle rays, humans, hermit crab, octopus, and sharks.

There is no exact answer to this question. There are thousands of different species that range from less than a centimeter to the giant clam weighing hundreds of pounds.

they are more related to roundworms

Bivalves are a class of mollusks that have two shells hinged together, while mollusks are a diverse phylum of invertebrates that include bivalves, snails, and octopuses. Bivalves primarily feed through filter feeding by pumping water in and out of their shells, while other mollusks have various feeding methods.

Barnacles live in the sea.

Some invertebrates that live in the water are:

* Shrimp * Lobster * Clams * Jellyfish * Starfish * Crabs * Mollusks * Snails

Lobsters are neither echinoderms nor mollusks like clams. They are also not arachnids. Instead, they are crustaceans, a subsection of arthropods.

Mollusks are invertebrates

There are over 50,000 known species of Mollusks! That figure makes them second only to the Arthropods in invertebrate phylum size.

I don't know that's whyI amasking you

gay animals

As like all other ocean creatures, they have gills. U have to look closely.

Hey, I tried using a Fret Saw. Success rate is poor as the shells are brittle and break. Still got a few of them sliced.

Nudibranchs, pronounced 'noodibrank', are a mollusc - basically speaking - a slug, and come in an enormous variety of sizes and colours.

Nudibranch itself means 'naked gills'. the plumes you see on them are literally their gills for breathing.

They are found in most habitats in all the oceans of the world.

Most nudibranchs are carnivorous. Some feed on sponges, others on hydroids, others on bryozoans, and some are cannibals, eating other sea slugs, or, on some occasions, members of their own species. Other groups feed on tunicates, barnacles, or anemones .

Nudibranchs mainly live in the ocean(salt water). They can be found in tide pools and deep water too. Most abundant in tropical waters, they are also found in arctic waters and everything in between too. There are even a few species that live in fresh water!
