Hibernation is a state of inactivity and metabolic depression in few endotherms [warm blooded animals – bear, rodents] and ectotherms [many reptiles like snakes, turtles and amphibians like frogs]. Notochord– It is a longitudinal rod that is made of cartilage and runs between the nerve cord and the diges… They are the creeping and burrowing vertebrates with epidermal scales. The characteristic features of Aves (birds) are the presence of feathers and most of them can fly except flightless birds (e.g., Ostrich). Notochord is present at some stage or it is replaced by a ring like vertebrae at adult stage. You are a member of a phylum Chordata. The rodents, bats and shrews constitute the largest order which is followed by the Primates, Cetartiodactyla and Carnivora, respectively. They are distant relatives because they both burrow under ground. The body contains tough skin with minute placoid scales. Limbs, when present, are two pairs.

This phylum has a combination of both invertebrate (Echinoderm) and chordate characteristics. Circulatory system consisting of a ventral thoracic heart and shows increasing structural complexities in keeping the oxygenated blood separate. Their regeneration power is usually good. Their body is  radial, bi radial, bilateral or without symmetry. Chordates (Chordata) are a group of animals that includes vertebrates, tunicates, lancelets. They have an elongated body bearing 6-15 pairs of gill slits for respiration. Some of them have adapted to fly or live in water. Phylum is a taxonomic ranking that comes third in the hierarchy of classification, after domain and kingdom. There are about 8,000 living reptiles species in the world today that inhabit all continents on Earth except Antarctica. The phylum itself is named after the longitudinal, flexible and rod shaped structure called the notochord located between the digestive tube and nerve cord of all embryonic stage chordates, and in some species of adults. Constantly changing body temperatures make life more difficult for the parasites. Fishes, amphibians and reptiles are poikilothermous (cold­blooded). They show sexual or asexual reproduction. The body does not contain any scales. The most distinguishing character that all animals belonging to this phylum have is the presence of notochord. Mammals have hair, fur and birds have feathers to help keep them warm. They … Single-layer epidermis; oral hood with cerii; Blood is colorless; circulatory system without heart. • Study of Paramecium with particular reference to locomotion, Osmoregulation and reproduction. The vertebrates have acquired a number of characteristics features in addition to the basic chordates characterizes which are of high adaptive value and as much they are readily distinguished from the invertebrate-chordates. They have long, rounded and eel-like body with scale less, glandular and smooth skin. On the other hand, all animals which do not possess vertebral column, are known as invertebrate. They inhabit in all sort of waters such as fresh, marine, brackish-water environment. PHYLUM CHORDATE-CLASSIFICATION Phylum Chordate is divided into three Sub-Phyla. They are Fish-like marine animals with laterally fattened body devoid of paired fins, skull and limbs. The word ‘Mammalia’ is derived from Latin word ‘mamma’ meaning "breast". They have powerful jaws with backwardly directed teeth. Phylum Chordata is divided into three subphyla: Urochordata, Cephalochordata, and Vertebrata. Pin It.

Fertilization is internal, development is direct; many of them are viviparous which give birth to young baby. During excretion, they release chiefly nitrogenous waste. As they have a close relationship with the chordates, so they are called chordates. Endoskeleton is fully ossified (bony) and the long bones are hollow with air cavities (, The digestive tract of birds has additional chambers, the. The class Osteichthyes is the largest group of vertebrates in the world and it contains more than 30,000 fish species which account for about 96% of all fish species. Digestive system is complete which has a muscular opening at the base of the tail. Sexes are separate; fertilization is internal and their development is direct. amzn_assoc_tracking_id = "mywebsit03240-20"; Some of them have electric organs (e.g., Torpedo) and some possess poison sting (e.g., Trygon). Vertebral column continues up to the tail end which divides the tail into upper and lowers lobes. SUB-PHYLUM: 1. Hemichordata, Sub phylum 2. They have streamlined body with terminal mouth.

Their skin is covered with. Classification of Phylum Chordata. The skin is thin, loose and dry with flight muscle in the thorax; sweat gland is absent. Vertebrates Classification. In the adults, however, these are totally obliterated and become transformed into other organs like endocrine system. The body is divisible into three regions, a proboscis, a collar and a trunk, the anterior end of which bears gill slits. Pharynx large, sac-like and perforated with numerous well-developed pharyngeal gill slits. Vertebrata. Subphylum UROCHORDATA, Herdmania, Salpa, Doliolum, Pyrosoma, … They are completely lung breathers; no skin or gill respiration. Embryologically, this nerve cord originates from the dorsal ectoderm. Some classifications also include the phylum Hemichordata with the chordates. In the adult stage, the notochord is replaced by a vertebral column. Central nervous system is dorsal, hollow and single. CEPHALOCHORDATA, SUB-PHYLUM: 3. Presence of the dorsal tubular nerve cord; Presence of the paired pharyngeal gill-slits. The members of subphylum Vertebrata possess.
