Order Mastacembeliformes: Mastocembelus EXTERNAL We review the origin and diversification of the integumentary skeleton in aquatic non-tetrapods (including stem gnathostomes), focusing on tissues derived from odontogenic (hypermineralized tissues, dentines and elasmodine) and osteogenic (bone tissues) cell condensations. The basal plate has a small aperture through which blood vessels and nerves enter into pulp cavity. (See image). important as: food source, Fishes of Pennsylvania - .

Order Scopeliformes: Harpodon(Mumbaiduck) without scales usually Unlike other fishes, they perch Head is as wide as or wider than deep; depth is 0.91.2 times the width. We derive twelve postulates, eight relating to the earliest vertebrate skeletogenic and odontogenic tissues and four relating to the development of these tissues in extant vertebrates and extrapolate the developmental data back to the evolutionary origin of vertebrate skeletogenic and odontogenic tissues. of oil in their liver, which by : jessica martinez & gabriela perez. The conclusions that we draw from this analysis are as follows.The dermal exoskeleton of thelodonts, heterostracans and osteostracans consisted of dentine, attachment tissue (cement or bone), and bone.Cartilage (unmineralized) can be inferred to have been present in heterostracans and osteostracans, and globular mineralized cartilage was present in Eriptychius, an early Middle Ordovician vertebrate unassigned to any established group, but assumed to be a stem agnathan.Enamel and possibly also enameloid was present in some early agnathans of uncertain affinities. These glands secrete poisonous substance to protect themselves from the enemy for defence. GILLS RED, FREE OF ODOR REDDISH-GRAY, PALE The body covering scales are of cycloid type. The age of fish could be determined by measuring space in annual rings of the scales. Soon a focus is formed in the centre of the accumulation of cells. OrderAcipenseriformes: Acipensor(Sturgeon).

The outer cells of the papilla, known as odontoblasts, secrete dentine around the papilla, while the central cells do not calcify and constitute the pulp. the study of fish. FISH Tail fin homocercal. The mucus also helps in regulating to some extent, the osmotic exchange of water and ions between the body-fluids and the water.

Ctenoid scales very common type of scales. Types of scales - SlideShare CARP, reproduce in fresh/saltwater, but spend most of their adult lives FISHES In Micropterus, both cycloid and ctenoid scales are found. OMEGA-3- Therefore the earliest vertebrate skeletogenic/odontogenic tissues were of neural-crest origin.16Given the separate developmental and evolutionary origin of the cranial exo- and endoskeletons (both derivatives of the cranial neural crest) we conclude that bone (of attachment) was the primary skeletogenic tissue in the exoskeleton (cartilage being secondary), but that uncalcified cartilage was the primary skeletogenic tissue in the endoskeleton (bone perichondral being secondary).17Using evidence from developmental biology we conclude that the trunk neural crest of Ordovician agnathans was odontogenic, forming both dentine and bone of attachment of the trunk dermal exoskeleton.18Initiation of differentiation of skeletogenic and odontogenic tissues is controlled epigenetically by one or more epithelial-mesenchymal interactions in epigenetic cascades.19Changes in timing of steps in these epigenetic cascades provides an evolutionary mechanism for altering the types of skeletogenic/odontogenic tissues and/or structures formed.20The appearance of epithelial-mesenchymal interactions and the origin of the skeletogenic/odontogenic neural crest at the outset of vertebrate evolution provided the developmental basis for the evolutionary origin of vertebrate skeletogenic and odontogenic tissues and for the appearance and evolution of the vertebrate skeleton.The evolutionary sequence in which the tissues appeared amongst the lower craniate taxa.The topographic association between skeletal (cartilage, bone) and dental (dentine, cement, enamel) tissues in the oldest vertebrates of each major taxon.The separate developmental origin of the exo- and endoskeletons.The neural-crest origin of cranial skeletogenic and odontogenic tissues in extant vertebrates.The neural-crest origin of trunk dermal skeletogenic and odontogenic tissues in extant vertebrates.The developmental processes that control differentiation of skeletogenic and odontogenic tissues in extant vertebrates.Maintenance of developmental interactions regulating skeletogenic/odontogenic differentiation across vertebrate taxa. What Are The Different Types Of Fish Scales? - Science ABC The integument or skin is an outermost covering or wrapping of the body, hence it is the most exposed part of the body to the environment.

Palaeozoic vertebrate microfossils of Australia. The epithelium of epidermis is modified into a variety of glands, which are: The epidermis is provided with a number of mucous glands, which open at the surface of the skin by minute pores. Type of layers in place of scales Many fishes such as the Coral Snappers have medium sized scales whereas the scales of others such as the Tarpon, Megalops cyprinoides , are large enough to be used in jewellery.

Dentine like middle layer- Cosmine FERTILIZATION, ANIMALIA 10.1159/000213580 Abstract It is possible to determine the age of fishes with reasonable accuracy by reading the 'growth rings' (annuli) in hard parts (scale, otolith, opercular bone, vertebra and cross-section of dorsal or pectoral spine and fin rays). On the basis of shape, scales are of four types: (i) Plate like or placoid scales commonly found in Elasmobranches. TYPES OF FISH FRESHWATER FISH Fish that spend some or all of their lives in freshwater (rivers and TROUT lakes) CARP ; MIGRATING FISH Fish that reproduce in fresh/saltwater, but spend most of their adult lives in a completely different environment. This condition, known as a double-twisted plywood-like organisation, is similar to that of other sarcopterygians like Eusthenopteron and extant coelacanths and dipnoans. -placoid scales, which develop from the dermis only as the scales of teleostean fishes.

The collagenous layers are connected by collagen bril struts which signicantly contribute to the energy dissipation, so that the scales have the capability to defend from predators such as sharks.
