MORPHOFUNCTIONAL STRUCTURE OF COMMON PIKE ESOX LUCIUS

Abstract

Esox Lucius pike primarily belongs to the kingdom of creatures, the chordova type, the pike-like series, the homeland of the pike, the pike type, and the species is the original pike. When investigating pike and fish in general, the utmost respect is paid to the external outline of this individual. To outline the body of the pike, they were initially washed with a trimmer vimir in order to visually detect the development of the anatomical storage areas of the three distinct planes. Pike is primarily a river fish, its body shape is arrow-like, drawn out, which helps the fish to collapse quickly, or to stand in the middle of the hunt. The length of a pike can reach up to one and a half meters, and the weight up to thirty kilograms. On the body of the pike there is a section of the head, a vest, a swimmer and a tail. These are the main anatomical warehouses and differentiate different types of fish. The color of the pike is dark gray with a silvery tint. Along the entire body, the skin of the pike is covered with a brush, go to the head plot, to the bottom plot, the winter cap in oblique rows, going one after another, the back is dark below the belly, and along the body you can see light spots of varying sizes Rotated along the sides of the body and across the body. The part of the pike's head is large, occupies about one third of the entire head, is flattened, flattened dorsoventrally, begins with the mouth opening. The pike is a good breeding pair and unpaired swimmers. Unpaired swimmers are dorsal, anal and caudal. The tail is divided into two parts, and there is a flattened surface. At the great head of the pike, their mouths, nose openings, and eyes are opening. The opening of the pike's head begins orally with a large oral opening, which extends right up to the front edge of the eye. The mouth opening has two slits, upper and lower, which form a mouth that reaches the rostral edge of the eyes. The mandible protrudes slightly forward and extends beyond the upper cleft. On the upper bone there is an aboral fold of the skin, which connects to the skull and encloses the side walls of the mouth, which is similar to the way of life of pikes. The eyeballs of the pike are spread dorsolaterally on the front of the head, have a spherical shape, but do not form sideways. The opening of the iris is large and has a round shape. Along the edges of the eye there is a fold of the skin, which is joined to the rostral wall of the eye. The winter plot is aborally grown and covered with a winter cover. From its rear edge there is a wide fold of skin stretching to the lower slit and what is called a winter weave. At once, the stench will surround the winter gap, or open it, which will connect one with one of the right and left sides. Rostrally in front of the eyes is the entrance to the nasal cavity. They are represented by two pairs of nostrils of different shapes, the nasal one is in the shape of a circle, and the aboral one is in the shape of an interchange. Directly below these openings, the empty space in the yak through the nostrils drains water when the pike collapses, thus changing the water in the sniffing capsule. The empty mouth begins with a large oral gap, which is surrounded by indestructible lips. The empty mouth will end with a pharynx. Like the organs of the head intestine, teeth and tongue are clearly visible here. The shape of the teeth is cone-shaped, the larger teeth of the pike are located on the lower slit. On the upper slit and on the lower palate, the stench is fractional and numerical.
