  • The life of Fish Fish Kingdom: Animalia Phylum: Chordata All fish are aquatic and are found in fresh and salt water throughout the world. There are three main classes: the jawless fish (Agnatha), bony fishes (Osteicthyes) and cartilaginous fishes (Chondrichthyes). The jawless fishes, such as lampreys and hagfish, are the only fish that have sucking mouthparts, which makes them dependent on a parasitic way of life. They are primitive fish and fins are either absent or poorly developed. Bony fish possess true ossified, internal skeletons to support the body tissues and a rigid skull of fused dermal bones. Most also have external scales covering the body and a bony flap, the operculum, covering a single gill exit. The spiracle is reduced or lost in bony fishes and the majority have swim bladders evolved from the primitive fish lung. Their eyes are large and of primary sensory importance. The fins are flexible and often able to be folded against the body. This is the biggest class of fish and includes about 20000 species. There are around 900 species of cartilaginous fish. Sharks and rays are two examples that belong to one subclass (Elasmobranchii). These differ from bony fishes in having flexible, cartilaginous skeletons, sometimes strengthened by salt deposits. Elasmobranchs are covered with tooth-like scales called denticles, which helps strengthen the body's structure. They have multiple, uncovered gill exits and they have a good sense of smell. They have long snouts and their jaws are ...
  • California Skate California Skate at Ocean Institute in Dana Point Ca. He is doing little dance at a class field trip. Although most people are probably familiar with stingrays, many are unaware of their cousin the skate. This bottom-dwelling, kite-shaped animal is found throughout the world in temperate and polar regions, as well as in deep waters of the tropics. More than 280 species of skate have been discovered, making this family the largest of all rays. Unlike stingrays, all skates give birth by laying distinctive, leathery egg cases. Skates are closely related to sharks and rays, possessing skeletons made of cartilage instead of bone; sharing this feature, these fishes comprise the elasmobranchs.
  • Scyliorhinus canicula,The small-spotted catshark or lesser spotted dogfish Sandykove,dublin,ireland. app.7m vis 13C water temp. The small-spotted catshark or lesser spotted dogfish, Scyliorhinus canicula, is a cat shark of the family Scyliorhinidae found on the continental shelves and uppermost slopes off Norway and the British Isles south to Senegal, including the Mediterranean between latitudes 63° N and 12° N. Its length is up to 1 m (3.3 feet) and it can weigh more than 6.5 lb (2 kg).[1]. It is found primarily over sandy, gravely or muddy bottoms at depths of a few meters down to 400 m.[2].The S. canicula is one of the most abundant elasmobranchs in the Northeast Atlantic and Mediterranean Sea. The majority of the populations are stable in most areas

  • Summer Salt Dive Center diving with Bull sharks Freshwater tolerance The bull shark is the best known of 43 species of elasmobranch in ten genera and four families to have been reported in fresh water.[14] Other species that enter rivers include the stingrays (Dasyatidae, Potamotrygonidae and others) and sawfish (Pristidae). Some skates (Rajidae), smooth dogfishes (Triakidae), and sandbar sharks (Carcharhinus plumbeus) regularly enter estuaries. Elasmobranchs' ability to enter fresh water is limited because their blood is normally at least as salty (in terms of osmotic strength) as seawater, through the accumulation of urea and trimethylamine oxide, but bull sharks living in fresh water reduce the concentration of these solutes by up to 50%. As a result, bull sharks living in fresh water need to produce twenty times as much urine as those in salt water.
  • Nature Of The Shark- The Short This is a five minute short/preview (though complete in itself) of my film of the INCREDIBLE beings known as Sharks!! I've spent three years filming sharks and gathering interviews as I both have tried to better know them and the world they inhabit, as well as become a more competent filmmaker and ecologist! I apologize ahead for some sound troubles (put volume up high or you wont be able to here a few guys speak), but am proud of this first work and hope you will enjoy it as well, and get a unique perspective on the grace and intelligence of sharks. I hope you will join the fight to protect our shark and ocean brethren around the world, so that everyone can have experiences like I have had for a long time to come!! I hope that you will come to appreciate the illusive yet inspiring, NATURE OF THE SHARK!! Thanks to my parents, family, so many friends, Ocean Blue Education and crew, Andrew Eldredge (MUSIC!), Shark Diver Mag, the sharks! and everyone who helped me out is so many ways! -also on a technical note, i'm often asked "did you film this yourself?" ( I guess to be expected when a ***ager makes a documentary on sharks) I did 100% the editing, and 95% of the filming myself (use a cannon HV20 in an equinox housing), but had huge help from so many people I briefly thanked above (especially my parents who funded this crazy venture), and was given some footage of myself in the water by Cara Smith and Vinnie Canabal, so extra credit to them! my old teacher and mentor ...
  • Loving Crocodile Real Science: The salt gland is an organ for excreting excess salts. It is found in elasmobranchs, seabirds, and some reptiles. In sharks, salt glands are found in the rectum, but in birds and reptiles, they are found in or on the skull, in the area of the eyes, nostrils or mouth. In crocodiles, the salt is excreted through the tongue.[1] Such glands work by active transport via sodium-potassium pump that moves salt from the blood into the gland, where it can be excreted as a concentrated solution. Salt glands function to maintain salt balance and allow marine vertebrates to drink seawater.[2] 1 John 4:16 "And we have known and believed the love that God hath to us. God is love; and he that dwelleth in love dwelleth in God, and God in him." You might not think of the crocodile as a particularly loving creature. In reality, the crocodile is among the most gentle and loving of parents. Mama crocodile lays between 40 and 80 eggs in a large nest. For the 90 days they take to hatch, she will keep close watch over them, even foregoing food so as not to leave the nest unattended. Even the father stays close to guard the eggs that are a delicacy to many animals. At the end of this three-month watch, the babies begin to chirp from within their eggs. Before long there may be dozens of babies chirping from the nest of buried eggs. This brings the mother who carefully uncovers the eggs, one by one. The young are only nine inches long and weigh just four ounces. Yet, the gentle and ...
