  2. Interesting facts about fish!! • Fish have been on the earth for more than 450 million years. • Fish were well established long before dinosaurs roamed the earth. • There are over 25,000 identified species of fish on the earth. • It is estimated that there may still be over 15,000 fish species that have not yet been identified. • There are more species of fish than all the species of amphibians, reptiles, birds and mammals combined. • 40% of all fish species inhabit fresh water, yet less than .01% of the earth's water is fresh water. • The spotted climbing perch is able to absorb oxygen from the air and will crawl overland using its strong pectoral fins. • Some fish like sharks don't posses an air bladder to help keep them afloat and must either swim continually or rest on the bottom. • Some fish make sounds by grating their teeth and others like some catfish make sounds from their air filled swim bladder. • Some species of fish can fly (glide) others can skip along the surface and others can even climb rock. • Fish have a specialized sense organ called the lateral line which works much like radar and helps them navigate in dark or murky water. • The largest fish is the great whale shark which can reach fifty feet in length. • The smallest fish is the Philippine goby that is less than 1/3 of an inch when fully grown. • Some species of fish have skeletons made only of cartilage. • Fish have excellent senses of sight, touch, taste and many possess a good sense of smell and 'hearing'. • Fish feel pain and suffer stress just like mammals and birds. • Tropical fish are one of the most popular pets in the U.S. • 95% of tropical fish mortality results from improper housing and nutrition. • Many tropical fish sold in the United States are harvested from the wild in Africa, Asia, and Central and South America.

  3. DEADLY FISH!! DEADLY FISH This is a bull shark. STONEFISH The worst of the scorpion fishes, the stonefish bears a toxin comparable to that of a cobra. This small but horribly ugly creature lives in coral reefs in the Pacific and Indian oceans and is camouflaged to resemble a coral lump. If you are "spined," the pain is instantaneous. In 10 minutes you'll likely collapse, thrashing and raving maniacally. If you survive six hours you'll probably live, though flesh near the wound will have sloughed away, your joints will ache and it will take a year to regain good health. GREAT WHITE SHARK Based on its size, strength, fearlessness and preference for feeding on marine mammals—as well as divers, swimmers and even kayak hulls—the great white is the deadliest shark. These prehistoric survivors grow to thousands of pounds. BULL SHARK Many shark species can do you in, but the bull makes this list because of its abundance, vile disposition and common occurrence near shore in turbid water, where the fish is rarely seen until it attacks. Bulls also adapt to fresh water and roam far up major rivers. SEA WASP Otherwise known as the box jellyfish, this member of the Cubozoa clan (not a true jellyfish) is about as big as a basketball, with 60 nearly invisible tentacles trailing up to 15 feet behind it. It calls the Indio-Pacific region home. Not everyone who comes into contact with those tentacles dies, but the excruciating venomous sting causes vomiting and breathing and heart problems. CANDIRU This translucent, yellow-eyed, eel-like parasitic catfish grows to a maximum length of one inch. It cannot kill you outright, but if you experience the wrath of one, you might wish it had. A native of the Amazon, the fish has a penchant for swimming into urethral openings of unprotected bathers—men and women alike. Once inside it pops open its spiny gill covers, which prevent it from being pulled out. The ensuing shock and infection have caused death, as has haemorrhaging resulting from attempts to remove it. Delicate surgery might be required. Also, the juice of two native fruits high in citric acid, both drunk and used externally where possible, can dissolve the gill spines and kill the fish.
