Introduction. In this tutorial you will be learning about the Linnaean system of classification used in the biological sciences to describe and categorize all living things. The focus is on finding out how humans fit within this system. In addition, you will discover part of the great diversity of life forms and come to understand why some animals are considered to be close to us in their.
Classification of Fish: Fish, the member of the Animalia Kingdom is classified into Phylum Chordata and Vertebrata Subphylum. Fishes poses notochord, tubular nerve chord, paired gills, segmentation of the body parts, post anal tail, ventral heart, and an endoskeleton to be the member of the Chordata.
A vertebrate is an animal with a spinal cord surrounded by cartilage or bone.The word comes from vertebrae, the bones that make up the spine.Animals that are not vertebrates are called invertebrates.Vertebrates include birds, fish, amphibians, reptiles, and mammals.The parts of the vertebrate skeleton are:. Braincase: A braincase or cranium protects the brain.
Chordate Definition. A chordate is an animal that belongs to the phylum Chordata, which is part of the Deuterostomes kingdom.Organisms in the Deuterostomes kingdom have a distinct characteristic: their anus develops before their mouth in early embryonic stages.
Vertebrate, any animal of the subphylum Vertebrata. They have backbones, from which they derive their name. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone.
PHYLUM CHORDATA The phylum Chordata includes many familiar animals such as fishes, frogs, snakes, birds, mammals and man. Also included in this phylum, but bearing little resemblance to the above animal groups, are the tunicates and the lancelets. Chordates display the.
Let’s discover what the classification of vertebrates is all about. Classification. Traditional classification groups the various vertebrates into seven classes based on anatomy and physiology. Agnatha are the jawless fish such as lampreys and eels. Chondricthyes are fish that have skeletons of cartilage such as sharks, rays and skates.
Animal classification is a matter of sorting out similarities and differences, of placing animals in groups and then breaking those groups apart into subgroups. The whole endeavor creates a structure—a hierarchy in which the large high-level groups sort out bold and obvious differences, while the low-level groups tease apart subtle, almost imperceptible, variations.
Some fish, such as lungfish, can breathe oxygen that is in the air. Fish are usually cold-blooded (ectothermic) but some fish, such as tuna, swordfish and mackerel sharks, are able to regulate the temperature in parts of their bodies. Classification of Fish. Fish are divided between jawless fish (Agnatha) and jawed fish.
Nervous systems, function and survival Invertebrates and vertebrates are compiled of many different cells, systems and functioning pathways all of which are maintained by homeostasis. In this essay I will discuss the connection between homeostasis and the nervous system; briefly compare an invertebrates and vertebrates nervous system; nerve cells and how an organism’s behaviour can be.
Jeffries (1986) provides descriptions and comparisons and argues for the placement of calcichordates near the Chordata. Other workers believe that calcichordates are closer to echinoderms. Reconstructions of these fossil organisms include visceral (pharyngeal or gill) slits that would suggest chordate affinities, but the mineralized skeleton was composed of calcite, like echinoderms, not bone.
Animals are a diverse group of organisms that include many subgroups such as arthropods, chordates, cnidarians, echinoderms, mollusks, and sponges. Animals also include a vast array of lesser-known creatures such as flatworms, rotifers, placazoans, lamp shells, and waterbears.

Platyhelminthes are commonly known as flatworms. Some of the examples of Platyhelminthes include tapeworms and flukes. These flatworms usually exist as parasites which feeds on its host or it can exist as non-parasitic animals such as the planarians (Schmidtea mediterranea).
