Each half of pectoral girdle (Fig. They serve as a sieve to prevent the escape of food through the gill-slits and to protect the gill filaments. The process of growth is maximum during : Plasma is red and nucleated, colourless RBC, Adult with radial symmetry and larva with bilateral symmetry. In this way a firm vertical plate of bone is formed, to the edge of which the caudal fin rays are attached fanwise in a symmetrical manner. It is divided into an axial skeleton which includes the skull, vertebral column and ribs, and appendicular skeleton that includes the girdles and supporting elements of fins. Basisphenoids are absent. This Indo-Gangetic riverine sps. The radials articulate with the posterior border of the pelvic bone. The remaining five arches are called branchial or gill-arches, diminishing in size from before backwards. (a) Anterior pro-otic which unites with its fellow of the opposite side in the floor of the brain case, just in front of the basioccipital; (b) Opisthotic in the posterior part of the capsule, external to the exoccipital; (c) Sphenotic above the pro-otic and forming part of the boundary of the orbit; (d) Pterotic above the exoccipital and opisthotic, forming a distinct lateral ridge and produced behind into a prominent pterotic process; and.

These bones do not, however, enter into the gape, and do not form the actual upper jaw of the adult fish. Match the following columns and select the correct option. The basibranchials are connected with one another and with the basihyal by cartilage so as to form a median ventral bar in the floor of the pharynx. The radials articulate with the scapula. NCERT DC Pandey Sunil Batra HC Verma Pradeep Errorless. Exoskeleton of Rohu Fish (Labeo rohita) comprises scales and fin-rays. This fish also called as ”Rui” or “Ruee” or Tapra. 15.6) is formed of: (i) A scapula, situated dorsally to the glenoid facets and developed partly as a replacing, partly as an investing bone; (ii) A coracoid situated ventrally to the glenoid facet and. All these bones form an inverted cup-like structure that lodges the internal ear. It is formed of a palato-pterygoquadrate which forms the upper jaw and a Meckel’s cartilage that forms the lower jaw in the embryonic stage. (B) Synteny conservation between rohu and zebrafish using Symap. Soft rays are segmented, often branched and biserial. Dentary meets with its fellow of the other side in the middle. The caudal fin (D) is the tail fin located at the end of the caudal peduncle and is used for propulsion. They are found in freshwater habitats in the tropics and subtropics of Africa and Asia. The opercular is a large, flat bone with a condyle which articulates with the hyomandibular.
