Vertebrates are animals that have backbones, including fish, amphibians, reptiles, birds, and mammals. They are characterized by having a backbone, muscular system, central nervous system, and endoskeleton. Invertebrates make up 97% of animal species but do not have backbones, instead using specialized cells to move. Examples of invertebrates include sponges, jellyfish, worms, insects, starfish, and snails.

Introduction Ostracoderms (shell-skinned) are of several groups of extinct, primitive, jawless fishes that were covered in an armour of bony plates. They appeared in the Cambrian, about 510 million years ago, and became extinct towards the end of the Devonian, about 377 million years ago. They were quite abundant during the upper Silurian and Devonian periods. Most of fossils of Ostracodermi were preserved in the bottom sediments of freshwater streams. However, the opinion is sharply divided as to whether their habitat was freshwater or marine. The first fossil fishes that were discovered were ostracoderms. The Swiss anatomist Louis Agassiz received some fossils of bony armored fish from Scotland in the 1830s. The ostracoderms resembled the present day cyclostomes (lampreys and hagfishes) in many respects and together with them constitute a special group of jawless vertebrates, the Agnatha. Characteristics: They use gills exclusively for respiration but not for feeding . Earlier chordates with gills used them for both respiration and feeding. Ostracoderms had separate pharyngeal gill pouches along the side of the head, which were permanently open with no protective operculum. mostly small to medium-sized fishes, protected by a heavy, bony dermal (derived from skin) armor. bottom-dwellers; filter-feeders or grazers. no paired fins, but many with stabilizing paired flaps on either side of head. (1) Ostracoderms were the first vertebrates. (2) They were popularly called armoured fishes. (4) They lived in freshwater. (5) They were bottom dwellers. (6) Their body was fish-like and did not exceed 30 cm in size. (7) Paired fins were absent. (8) Median and caudal fins were present. (9) The caudal fin was of heterocercal type. (10) The head and thorax were covered by heavy armour of bones. It protected ostracoderms from the giant scorpion like arthropods, eurypterids. (11) Bony skull was well developed. (12) Mouth was mostly present on the ventral side. (13) They were having large number of gill slits. (14) The nervous system had 10 pairs of cranial nerves. (15) The head had a pair of lateral eyes, and a median pineal eye. (16) They were filter feeders, feeding like a vacuum cleaner. (17) The endoskeleton was either bony or cartilaginous.

Gnathostomata

Govt.college,Nagda, ujjain.M.P

Introduction Gnathostomata are the jawed vertebrates. (gnathos= "jaw" + (stoma)="mouth". It comprises roughly 60,000 species. (99% of all living vertebrates). Living gnathostomes have teeth, and paired appendages. A horizontal semicircular canal is present in the inner ear. Myelin sheaths is present on the neurons. Adaptive immune system uses V(D) J recombination ( it is the mechanism of somatic recombination that occurs only in developing lymphocytes during the early stages of T and B cell maturation. VDJ recombination is the process by which T cells and B cells randomly assemble different gene segments – known as variable (V), diversity (D) and joining (J) genes – in order to generate unique receptors (known as antigen receptors) that can collectively recognize many different types of molecule. While Agnatha (petromyzon and hagfish) use genetic recombination in the variable lymphocyte receptor gene. It is now assumed that Gnathostomata evolved from ancestors that already possessed a pair of both pectoral and pelvic fins. In addition to this, some placoderms were shown to have a third pair of paired appendages, that had been modified to claspers in males and basal plates in females—a pattern not seen in any other vertebrate group. It is believed that the jaws evolved from anterior gill support arches that had acquired a new role, being modified to pump water over the gills by opening and closing the mouth more effectively – the buccal pump mechanism. Presence of Calcified, bony skull and vertebra are the characteristic features of Gnathostomata (fishes, amphibians, reptiles, birds and mammals). Pelvic fins are situated just in front of the anus. Interventrals and basiventrals present in the backbone. These are the elements of the backbone which lie under the notochord, and match the basidorsals and interdorsals respectively. Gill arches which lie internally to the gills and branchial blood vessels, contrary to the gill arches of all jawless craniates, which are external to the gills and blood vessels. A horizontal semicircular canal in the inner ear. Paired nasal sacs which are independent from the hypophysial tube. There are numerous other characteristics of the soft anatomy and physiology (e.g. myelinated nerve fibres, sperms passing through urinary ducts, etc.), which are unique to the gnathostomes among extant craniates, but cannot by observed in fossils.

Briefly discuss the adaptive changes seen in the chordates over the o.pdf

monikajain201

Briefly discuss the adaptive changes seen in the chordates over the other animal phyla? Solution Animals in the phylum Chordata reveal four key features that appear at some point all through their development. a. Notochord - The chordates are called for the notochord: a flexible, rod-shaped design that is found within the embryonic stage of most chordates and also in the adult stage of some chordate species. It is found between the intestinal pipe and the nerve cord, providing skeletal help through along the body. In some chordates, the notochord acts while the primary axial support of the human body throughout the animal\'s lifetime. In vertebrates, the notochord is provide during embryonic development, of which time it induces the development of the neural pipe which acts as an assistance for the developing embryonic body. The notochord, however, is replaced by the vertebral column (spine) in most adult vertebrates. b.Dorsal Hollow Nerve Cord - The dorsal hollow nerve cord derives from ectoderm that sheets into a worthless pipe all through development. In chordates, it is found dorsally (at the top of the animal) to the notochord. In contrast to the chordates, other animal phyla are known by strong nerve cables which are positioned either ventrally or laterally. The nerve cord within most chordate embryos develops into the brain and spinal cord, which include the main anxious system. c.Pharyngeal Slits - Pharyngeal slits are openings in the pharynx (the place just posterior to the mouth) that expand to the surface environment. In organisms that are now living in aquatic surroundings, pharyngeal slits allow for the quit of water that enters the mouth all through feeding. Some invertebrate chordates use the pharyngeal slits to filtration food out of the water that enters the mouth. In vertebrate fishes, the pharyngeal slits develop into gill arches, the bony or cartilaginous gill supports. In most terrestrial animals, including mammals and birds, pharyngeal slits are providing just during embryonic development. In these animals, the pharyngeal slits develop into the jaw and inner ear bones. d.Post-anal Tail - The post-anal tail is a posterior elongation of the human body, increasing beyond the anus. The trail contains skeletal things and muscles, which give a way to obtain locomotion in aquatic species. In some terrestrial vertebrates, the trail also assists with stability, courting, and signaling when risk is near. In individuals and other apes, the post-anal tail is provide during embryonic development, but is vestigial as an adult..
