Pelecypoda is a class of marine and freshwater molluscs that have compress bodies enclosed by a shell into two hinged parts. Members of pelecypoda class include; mussel, clam, oysters and scallops among others.

Pelecypoda, also known as bivalve mollusks, are filter feeders. They feed by filtering small particles, like plankton and detritus, from the water using their gills. This feeding strategy allows them to obtain nutrition while living sedentary lifestyles in marine or freshwater habitats.
The pelecypoda, also known as bivalve mollusks, have been around for over 500 million years and can still be found today in various aquatic environments worldwide. Their fossil record dates back to the early Paleozoic era.

hatchet-footed mollusks
The common name oyster is used for a number of different groups of bivalve mollusks. Bivalves are mollusks belonging to the class Bivalvia. They have two-part shells, and typically both valves are symmetrical along the hinge line. The class has 30,000 species, including scallops, clams, oysters and mussels. Other names for the class include Bivalva, Pelecypoda, and Lamellibranchia.
Bivalves are mollusks belonging to the class Bivalvia. They typically have two-part shells, with both valves being symmetrical along the hinge line. The class has 30,000 species, including scallops, clams, oysters and mussels. Other names for the class include Bivalva, Pelecypoda, and Lamellibranchia. Bivalves are exclusively aquatic; they include both marine and freshwater forms. However some, for instance the mussels, can survive out of water for short periods by closing their valves. Bivalves are unique among the mollusks for lacking a radula; they feed by siphoning and filtering large particles from water. Some bivalves are epifaunal: that is, they attach themselves to surfaces in the water, by means of a byssus or organic cementation. Others are infaunal: they bury themselves in sand or other sediments. These forms typically have a strong digging foot. Some bivalves, such as scallops, can swim.
well, there's about 32 phyla all together and phyla is plural for phylum, the only phylum that has vertebrates is phylum chordata(chordates) the characteristics of chordates are that MOST of the classes in there are vertebrates, 2 of the classes in the phylum is invertebrates, i don't know why they're even in there but they are, anyways, the other rest of the classes are vertebrates, that includes mammalia(mammal),aves(birds) reptilia(reptiles)the 3 types of fishes, that includes chondrichthyes(cartilage fishes, for example sharks)osteichthyes (that's what i consider the "normal" fish, it means bony fishes, for example, sea horses, the fishes that American eats) and the last one is agnatha(which are jawless fishes that has no jaws, their mouths are like worms, just round with teeth all over the mouth, that's what i consider "abnormal" fishes and i think they're related to worms). Now to the invertebrates, the invertebrates' population is WAY WAY WAY bigger than the vertebrates because of the phylum arthopods( that means they have alot of legs, I'm talking about more than 3 pairs of legs) they include alot of classes which I'm not going to talk about because they're too many, but I'll talk about the basics, which are crustacea(crustaceans, it's actually a subphylum but the classes are just too much, they have 5 pairs of legs or more, for example cray fishes, crabs, shrimps, and more) there's insecta(which are insects and i don't call them "bug" because bugs means more than insects, insects have 6 MAIN legs and usually with a wings, they're the only invertebrates that can fly so catterpillars have alot of legs BUT they have 6 main legs, so a catterpillar is an insect ) there's class arachnida(arachnids, which include spiders, mites, scorpions and more, they're NOT insects because they have 4 PAIRS of legs and they only have 2 segmented parts that are closely jointed togethor, the abdoment ( which i consider the "buttocks" it's where the web comes out of, and the front region is just the head, so an insect has 3 segments, that's why they're different) now there's millipedes( centipedse that has ALOT of segments and i think 1 pair of legs on each, I'm not sure because i don't study about them,)there's millipedes(which is just dangerous and longer, and has alot of legs) there's garden millipedes( which are millipedes that are blind) and 1 last thing. arthropods is the most famous for it's population, they're the largest phylum in the animallia kingdom. Now for the most strange phylum, echinoderms(my favorite phylum of all) echinoderms includes animals that lives under water that does not have a brain, no head, they can be radial or bisymmetric, they all live in SALT water, nothing in fresh water, there's 8 classes of echinoderm and i know them all, but 2 of the classes are extinct and the 1 of the class(concentrycloidea, i might spelled it incorrectly) is the lastest and has only 2 species so far, which is sea dasies. The other 5 classes are the main classes of echinoderms, they are crinoidea( sea lilies, the most different of all classes) there's asteroidea(which are starfishes, the easiest echinoderms according to my opinion)there's echinoidea(which are sea urchins and sea dollars)there's holothuroidea(which are sea cucumbers) there's ophuiroidea(which are brittle stars, the largest of all classes of echinoderms and the best swimmer) most of echinoderms are poisonous, that comes out under them. They all have poidea(tube feets) under them for transporations, they all have different diet. Now the 2nd biggest phylum is mollusca or molluska(same thing)which has 9 classes( i think) which are alot, but I'm going over only 3 of them which are gastropoda(sea slugs and snails)there's pelecypoda(which are basically bivalves, they include mussles, clams, oysters,scallops and more)there's class cephalopoda(which are the molluscs without shells, that includes squids, octopuses, cuttle fish and alot more.Now there's the worm phyla, which includes alot of phyla which are really hard to learn about. I know it was long, but that IS the basics.
