Sex is the trait that determines whether a sexually reproducing animal or plant produces male gametes or female ones. The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. Unlike most organ systems, the sexes of differentiated species often A very fine freshwater fish is the Murray cod, which sometimes weighs Too lb; and the golden perch, found in the same river, has rare beauty of colour. Male water striders exhibit forced copulation on the female. Famous representatives of these orders are The terminal portion of the ejaculatory duct may be sclerotized to form the intromittent organ, the aedeagus. The Anatidae are the biological family of water birds that includes ducks, geese, and swans.The family has a cosmopolitan distribution, occurring on all the world's continents except Antarctica.These birds are adapted for swimming, floating on the water surface, and in some cases diving in at least shallow water.The family contains around 174 species in 43 genera. Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes.A termite nest is also known as a During sexual reproduction, male and The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm or eggs are released; the sex of a fish can often be A pair of intromittent organs of male squamates (snakes, lizards and worm lizards). Noun. The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction.Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. Sharks are a group of elasmobranch fish characterized by a cartilaginous skeleton, five to seven gill slits on the sides of the head, and pectoral fins that are not fused to the head. It is a reproductive, intromittent organ that additionally serves as the urinal duct. The infraorder name Isoptera is derived from the Greek words iso (equal) and ptera (winged), which refers to the nearly equal size of the fore and hind wings. " Fish reproductive organs include testes and ovaries.In most species, gonads are paired organs of similar size, which can be partially or totally fused. Fish reproductive organs include testes and ovaries.In most species, gonads are paired organs of similar size, which can be partially or totally fused. Osteichthyes (/ s t i k i. i z /), popularly referred to as the bony fish, is a diverse taxonomic group of fish that have skeletons primarily composed of bone tissue.They can be contrasted with the Chondrichthyes, which have skeletons primarily composed of cartilage.The vast majority of fish are members of Osteichthyes, which is an extremely diverse and The fish's hyomandibula bone in the hyoid region behind the gills diminished in size and became the stapes of the amphibian ear, an adaptation necessary for hearing on dry land. Termite" derives from the Latin and Late Latin word termes ("woodworm, white ant"), altered by the influence of Latin terere ("to rub, wear, erode") from the earlier word tarmes.A termite nest is also known as a Male water striders exhibit forced copulation on the female. The male reproductive organ used for sexual intercourse that in the human male and some other mammals is also used for urination; the tubular portion of the male genitalia (excluding the scrotum). Fish physiology is the scientific study of how the component parts of fish function together in the living fish. Another standard type is known as Internal fertilization. The term was initially used as a general adjective for animals that could live on land or in water, including seals and otters. The female clitoris is homologous to the male penis. Sexual intercourse, or copulation, is the deposition of sperm into a female via a male intromittent organ.In humans, the intromittent organ is the penis, and sperm are deposited into the vagina, where they make their way to towards the uterus to fertilize an egg. Modern sharks are classified within the clade Selachimorpha (or Selachii) and are the sister group to the rays.However, the term "shark" is also used to refer to extinct shark-like members of the The electric organ is an organ that an electric fish uses to create an electric field. There may also be a range of secondary organs that increase reproductive fitness. Etymology. The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. The remainder of the male reproductive system is derived from embryonic mesoderm, except for the germ cells, or spermatogonia, the eating of insects is taboo in cultures that have other protein sources such as fish or livestock. They have backbones, from which they derive their name. penis (plural penises or penes) The male reproductive organ used for sexual intercourse that in the human male and some other mammals is also used for urination; the tubular portion of the male genitalia (excluding the scrotum)The female clitoris is homologous to the male penis.. Robin Williams: See, the problem is that God gives men a brain and a In some fish, the gonopodium, andropodium, and claspers are intromittent organs (to introduce sperm into the female) developed from modified fins. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm or eggs are released; the sex of a fish can often be The adipose fin is a soft, fleshy fin found on the back behind the dorsal fin and just forward of the caudal fin. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone. Noun. A very fine freshwater fish is the Murray cod, which sometimes weighs Too lb; and the golden perch, found in the same river, has rare beauty of colour. 0. As a result, the female will struggle with the male to reduce the detrimental effects. The reproductive system of an organism, also known as the genital system, is the biological system made up of all the anatomical organs involved in sexual reproduction.Many non-living substances such as fluids, hormones, and pheromones are also important accessories to the reproductive system. 0. penis (plural penises or penes) The male reproductive organ used for sexual intercourse that in the human male and some other mammals is also used for urination; the tubular portion of the male genitalia (excluding the scrotum)The female clitoris is homologous to the male penis.. Robin Williams: See, the problem is that God gives men a brain and a It is a reproductive, intromittent organ that additionally serves as the urinal duct. Los telesteos (Teleostei) son una infraclase de peces seos actinopterigios que incluye el 96 % de todas las especies de peces existentes.Se han descrito ms de 26 000 especies, organizadas en unos 40 rdenes y unas 450 familias.Su tamao va desde el pez remo gigante (Regalecus glesne), que puede medir ms de siete metros, o el pez luna (Mola mola), que puede alcanzar They have backbones, from which they derive their name. The the anal fin of the male may be modified into an intromittent organ by means of which internal fertilization takes place. Since 1995 the Devil's Hole Pupfish has been in a nearly steady decline, where it was close to extinction at 3568 fish in 2013. Unlike most organ systems, the sexes of differentiated species often The terminal portion of the ejaculatory duct may be sclerotized to form the intromittent organ, the aedeagus. penis (plural penises or penes) The male reproductive organ used for sexual intercourse that in the human male and some other mammals is also used for urination; the tubular portion of the male genitalia (excluding the scrotum)The female clitoris is homologous to the male penis.. Robin Williams: See, the problem is that God gives men a brain and a Another standard type is known as Internal fertilization. vertebrate, also called Craniata, any animal of the subphylum Vertebrata, the predominant subphylum of the phylum Chordata. The vertebrates are also characterized by a muscular system consisting primarily of bilaterally paired masses and a central nervous system partly enclosed within the backbone. During sexual reproduction, male and Fish physiology is the scientific study of how the component parts of fish function together in the living fish. The remainder of the male reproductive system is derived from embryonic mesoderm, except for the germ cells, or spermatogonia, the eating of insects is taboo in cultures that have other protein sources such as fish or livestock. A pair of intromittent organs of male squamates (snakes, lizards and worm lizards). For this to happen, the male sperm has to be introduced into the female bodys reproductive tract through an intromittent organ. The genital papilla is a small, fleshy tube behind the anus in some fishes, from which the sperm or eggs are released; the sex of a fish can often be Sexual Intercourse Definition.

The electric organ is an organ that an electric fish uses to create an electric field. Electric organs are derived from modified muscle or in some cases nerve tissue, and have evolved at least six times among the elasmobranchs and teleosts. The fish's hyomandibula bone in the hyoid region behind the gills diminished in size and became the stapes of the amphibian ear, an adaptation necessary for hearing on dry land. Electric organs are derived from modified muscle or in some cases nerve tissue, and have evolved at least six times among the elasmobranchs and teleosts.
