They comprise 321 living species placed in 68 genera, 18 families and 5 suborders, but approximately half of the species diversity is occupied by deep-sea ceratioids distributed among ... Fish Reproduction and Development. Nearly all fish reproduce sexually, and most species have separate sexes. Those without separate sexes avoid self-fertilization by producing sperm and eggs at different times. Each fish typically produces a large number of gametes. In most fish species, fertilization takes place externally. These fish are ...Evolution of the inner ear: Insights from jawless fish. ScienceDaily .

Your Inner Fish, hosted on PBS by fish paleontologist Neil Shubin of Tiktaalik fame, blends fishy fables with embryology, genetics, and human anatomy. Shubin mingles observable wonders of biology with evolutionary explanations for their origin. He claims the human body itself contains the evidence for evolution and that “we are, every one of ...There are many species of Chinese freshwater fish that live 2-4 years; anadromous salmon generally live 3-6 years; many medium and large freshwater fishes, such as black carp, grass carp, silver carp, and bighead carp, generally live 7-8 years. Few fish live more than 10 years old, but some can live up to 15-20 years.The scientific definition of fish is complex and can be a little confusing. Here is a much simplified definition. Fish are: Chordates, they have a backbone or notochord (cartilaginous support). Live almost entirely in water. Have apparatus to extract oxygen from water (gills). Have appendages without digits (fins). Are generally ectothermic.Frillish. Black. With its thin, veil-like arms wrapped around the body of its opponent, it sinks to the ocean floor. White. They paralyze prey with poison, then drag them down to their lairs, five miles below the surface. Black 2. White 2. If its veil-like arms stun and wrap a foe, that foe will be dragged miles below the surface, never to return.

Evolution took advantage of a quirk of fish genetics to develop electric organs. All fish have duplicate versions of the same gene that produces tiny muscle motors, called sodium channels. Electric fish turned off one copy of the sodium channel gene in muscle, turned it on in other cells and voila: a new organ was born.Evolution took advantage of a quirk of fish genetics to develop electric organs.
