Larvae (very young forms that differ considerably from the juveniles and adults), when they do occur, differ in structure from the larvae of nonchordates. Internal fertilization, viviparity (giving birth to young that have undergone embryological development), and parental care are common in tunicates and vertebrates.

The two non extinct major groups within this phyla are Cephalochordata and Urochodata.

# data[].attributes.body
Cephalochordata are that they are segmented marine animals that possess elongated bodies with a notochord that extends the length of the body, extending from head to tail, persisting throughout the animal's life. Urochodata marine filter feeders with a water-filled, sac-like body structure and two tubular openings, known as siphons, through which they draw in and expel water.

# data[].attributes.body
All chordates also possess, at least briefly, pharyngeal gill slits. The gill slits allow water to vent out the side of the body, after it has passed over the gills.

Distinction of how groups are different 

# data[].attributes.body
Demospongiae are the largest porifera and they are found in all parts of the ocean. Hexactinellida are the medium size porifera and they can be found all over the world but are most populous in the Antarctic waters. Calcarea are the smallest porifera and they can be found all over the world but are most populous in temperate waters such as the Indian Ocean.

# data[].attributes.body
They have no true muscular system. Lack sensory organs, like a nervous system and are often amorphous and asymmetrical. No anterior, posterior, or oral surfaces.

It starts off as a zygote, then goes to the blastula stage which is a hollow sphere, after that it is a amphiblastula larva, and is able to move. After this it turns into the sponge and then finally settles down.

# data[].attributes.body
The chordate life cycle begins with fertilization. In its primitive form, fertilization occurs externally, in the water. Asexual reproduction takes place in tunicates and in some vertebrates. Hermaphroditism is found in tunicates and some fishes, but otherwise the sexes are separate.

There are two major groups with in this phyla Medusozoa and Myxozoa.

# data[].attributes.body
Medusozoa are different types of jellyfish and Myxozoa are parasites.

# data[].attributes.body
Cnidarians form an animal phylum that are more complex than sponges, about as complex as ctenophores (comb jellies), and less complex than bilaterians, which include almost all other animals. However, both cnidarians and ctenophores are more complex than sponges as they have: cells bound by inter-cell connections and carpet-like basement membranes; muscles; nervous systems; and some have sensory organs. Cnidarians are distinguished from all other animals by having cnidocytes that fire like harpoons and are used mainly to capture prey. In some species, cnidocytes can also be used as anchors.

It starts off as a Larva and searches for site to land. Then a Polyp grows, the the Polyp strobilates, and finally the Medusa grows.

# data[].attributes.body
They can develop from an unfertilized egg, asexually. While others have two kinds of eggs, one kind forms females and the other kind develops into degenerate males. These individuals copulate resulting in a fertilized egg developing within the rotifer.

# data[].attributes.body
There are three different major groups within the phyla Monogononta, Bdelloidea, and Seisonidea

# data[].attributes.body
Monogononta are found is mostly freshwater but also in soil and marine environments. Monogononts generally have a reduced corona, and each individual has a single gonad, which gives the group its name. Bdelloidea have the ability to survive in dry, harsh environments by entering a state of desiccation-induced dormancy (anhydrobiosis) at any life stage. Seisonidea are considered to have diverged from the other rotifers early on, and in one treatment is placed in a separate class Seisonoidea. They have a large and elongate body with reduced corona.

# data[].attributes.body
The general body plan of a rotifer consists of four basic regions: head, neck, trunk (body), and the foot. In most species, the head carries a corona (crown) of cilia that draws a vortex of water into the mouth, which the rotifer sifts for food. The food itself is ground by the trophi (jaws), located just behind the mouth in the pharynx (throat).

# data[].attributes.body
Most species hatch as miniature versions of the adult. Sessile species, however, are born as free-swimming larvae, which closely resemble the adults of related free-swimming species. Females grow rapidly, reaching their adult size within a few days, while males typically do not grow in size at all.

# data[].attributes.body
Unlike many other phylum the platyhelminthes are conceived and hatch as smaller versions of their adult. They do not go through different appearance stages.

# data[].attributes.body
The four major groups that the phyla is divided into are Turbellaria, Trematoda, Monogenea and Cestoda.

# data[].attributes.body
Turbellaria refers to the "whirlpools" of microscopic particles created close to the skins of aquatic species by the movement of their cilia. Trematoda are flattened oval or worm-like animals, usually no more than a few centimetres in length, although species as small as 1 millimetre. Monogenea are mall parasitic flatworms mainly found on skin or gills of fish. They are rarely longer than about 2 cm. A few species infecting certain marine fish are larger and marine forms are generally larger than those found on fresh water hosts. Cestoda are referred to as cestodes. The best-known species are commonly called tapeworms. All cestodes are parasitic and their life histories vary, but typically they live in the digestive tracts of vertebrates as adults, and often in the bodies of other species of animals as juveniles.

# data[].attributes.body
Platyhelminthes are bilaterally symmetrical animals: their left and right sides are mirror images of each other; this also implies they have distinct top and bottom surfaces and distinct head and tail ends. Like other bilaterians, they have three main cell layers while the radially symmetrical cnidarians and ctenophores have only two cell layers.

# data[].attributes.body
They are hermaphrodytic, meaning they can produce both ova and sperm. Both kinds of reproductive cells are released into the central body cavity. The fertilized ova are released into the environment along with waste materials. The eggs hatch into miniature versions of their parents.

# data[].attributes.body
The fertilized eggs develop into trochophore larvae, which live as plankton. Later they sink to the sea-floor and metamorphose into miniature adults: the part of the trochophore between the apical tuft and the prototroch becomes the prostomium. A small area round the trochophore's anus becomes the pygidium. A narrow band immediately in front of that becomes the growth zone that produces new segments; and the rest of the trochophore becomes the peristomium.

# data[].attributes.body
The two major groups of this phyla are polychaetes and clitellates.

# data[].attributes.body
Plychaete have a pair of fleshy protrusions called parapodiathat bear many bristles, called chaetae, which are made of chitin. As such, polychaetes are sometimes referred to as bristle worms. Clitellates are segmented worms characterised by the clitellum or girdle which is located near the head end of mature individuals. The mouth is on the ventral surface and is overhung by the prostomium (proboscis). The brain is not located in the head but in one of the body segments.

# data[].attributes.body
Their bodies are long, with segments that are divided externally by shallow ring-like constrictions called annuli and internally by septa at the same points, although in some species the septa are incomplete and in a few cases missing. Most of the segments contain the same sets of organs, although sharing a common gut, circulatory system and nervous system makes them inter-dependent.

# data[].attributes.body
Polychaetes can reproduce asexually, by dividing into two or more pieces or by budding off a new individual while the parent remains a complete organism. Clitellates are full hermaphrodites, although in a few leech species younger adults function as males and become female at maturity. All have well-developed gonads, and all copulate.

# data[].attributes.body
When the mollusca is a larva it feeds on floating food particles by using the two bands of cilia around its "equator" to sweep food into the mouth, which uses more cilia to drive them into the stomach, which uses further cilia to expel undigested remains through the anus.

# data[].attributes.body
The three major groups of this phyla are Gastropods, Bivalves, Cephalopods.

# data[].attributes.body
Gastropods have bilateral symmetry. Have both shells and not. The foot comes out of the stomach area. Bivalves are 2 shelled that have a hinge connecting the two. They are filter feeders, they use straw like organs to collect food/water. Cephalopods have tentacles that come out of the head. Move using jet propulsion.

# data[].attributes.body
The body is divided into two functional regions, the head-foot and the visceral lump. The head-foot is the part you see most easily in slugs and snails. It is mostly a muscular organ covered in cilia and rich in mucous cells, which the mollusc uses to move around, it normally tapers to a tail at one end and has a head incorporated in the front. The head includes a mouth, eyes and tentacles, the last two may be much reduced or even absent. In those species with shells the head-foot can be drawn into the shell. The rest of the body is the visceral mass, this is entirely nonmuscular and contains the organs of digestion and reproduction, it includes the gonads, the kidney, the heart and the digestive diverticulum.

# data[].attributes.body
The most basic molluscan larva is a trochophore, which is planktonic. Eventually, the larva sinks to the seafloor and metamorphoses into the adult form. While metamorphosis is the usual state in molluscs, the cephalopods differ in exhibiting direct development: the hatchling is a 'miniaturized' form of the adult.

# data[].attributes.body
Newly born arthropods have diverse forms, and insects alone cover the range of extremes. Some hatch as apparently miniature adults. Many insects hatch as grubs or caterpillars, which do not have segmented limbs or hardened cuticles, and metamorphose into adult forms by entering an inactive phase in which the larval tissues are broken down and re-used to build the adult body.

# data[].attributes.body
The four major groups within this phyla are Crustacea, Myriapoda, Hexapoda, and Chelicerata.

# data[].attributes.body
Crustacea have an exoskeleton, which they moult to grow. They are distinguished from other groups of arthropods, such as insects, myriapods and chelicerates, by the possession of biramous (two-parted) limbs, and by their larval forms, such as the nauplius stage of branchiopods and copepods. Myriapoda, Although their name suggests they have myriad(10,000) legs, myriapods range from having up to 750 legs (the millipede Illacme plenipes) to having fewer than ten legs. Hexapoda are named for their most distinctive feature: a consolidated thorax with three pairs of legs. Most other arthropods have more than three pairs of legs. Chelicerata originated as marine animals, possibly in the Cambrian period, but the first confirmed chelicerate fossils, eurypterids, date from 445 million years ago in the Late Ordovician period.

# data[].attributes.body
Arthropods are invertebrates with segmented bodies and jointed limbs. The exoskeleton or cuticles consists of chitin, a polymer of glucosamine. The cuticle of many crustaceans, beetle mites, and millipedes (except for bristly millipedes) is also biomineralized with calcium carbonate.

# data[].attributes.body
A few arthropods, such as barnacles, are hermaphroditic, that is, each can have the organs of both sexes. However, individuals of most species remain of one sex their entire lives. A few species of insects and crustaceans can reproduce by parthenogenesis, especially if conditions favor a "population explosion". However, most arthropods rely on sexual reproduction, and parthenogenetic species often revert to sexual reproduction when conditions become less favorable.

# data[].attributes.body
Some echinoderms brood their eggs. This is especially common in cold water species where planktonic larvae might not be able to find sufficient food. These retained eggs are usually few in number and are supplied with large yolks to nourish the developing embryos. In starfish, the female may carry the eggs in special pouches, under her arms, under her arched body or even in her cardiac stomach. Also Asexual reproduction in the planktonic larvae occurs through numerous modes. They may autotomise parts that develop into secondary larvae, grow buds or undergo paratomy.

The three non extinct major groups within this phyla are Crinozoa, Asterozoa, and Echinozoa.

# data[].attributes.body
Crinozoans are characterised by a mouth on the top surface that is surrounded by feeding arms. They have a U-shaped gut, and their anus is located next to the mouth. Asterozoa has a star-shaped body and radially divergent axes of symmetry. The subphylum includes the two classes Asteroidea, the starfish, and Ophiuroidea, the brittle starsand basket stars, and the extinct order Somasteroidea. Echinozoa is a subphylum of free-living echinoderms in which the body is essentially globoid with meridional symmetry. Echinozoans lack arms, brachioles, or other appendages, and do not at any time exhibit pinnate structure.

# data[].attributes.body
Echinoderms evolved from animals with bilateral symmetry. Although adult echinoderms possess pentaradial, or five-sided, symmetry, echinoderm larvae are ciliated, free-swimming organisms that organize in bilateral symmetry which makes them look like embryonic chordates. Later, the left side of the body grows at the expense of the right side, which is eventually absorbed. The left side then grows in a pentaradially symmetric fashion, in which the body is arranged in five parts around a central axis.

# data[].attributes.body
They are nearly all gonochoric, though a few species are hermaphroditic. The eggs and sperm cells are typically released into open water, where fertilization takes place. The release of sperm and eggs is synchronised in some species, usually with regard to the lunar cycle. One species of seastar, Ophidiaster granifer, reproduces asexually by parthenogenesis. In certain other asterozoans, the adults reproduce asexually for a while before they mature after which time they reproduce sexually. In most of these species, asexual reproduction is by transverse fission with the disc splitting in two.
