[Fish fact 1] An American tourist died in 2002 after being stung by the deadly Irukandji jellyfish off the waters of Australia’s Great Barrier Reef. This jellyfish is only the size of a thumbnail but can have three-feet-long tentacles. Most jellyfish have stingers on their tentacles, but the Irukandji jellyfish has stingers on its bell piece as well.
[Fish fact 2] Scientists have developed antivenom for box jellyfish stings. In Australia, where box jellyfish live, ambulances and hospitals keep the life-saving venom on hand.
[Fish fact 3] Sharks do not have scales. Instead their skin is covered with denticles, which give the skin its roughness. As sharks grow, the denticles fall off and are replaced by larger ones.
[Fish fact 4] Tilapia are ideal for farming because they reproduce quickly, eat pretty much anything, don't mind overcrowding, and can live in any type of water.
[Fish fact 5] The first written account of a shark attack is found in Herodotus’ (c. 484–425 B.C.) description of hordes of “monsters” devouring the shipwrecked sailors of the Persian fleet.
[Fish fact 6] Crabs are crustaceans (have an exoskeleton) and arthropods (have segmented appendages).
[Fish fact 7] Shipwrecked sailors or ditched airman may sometimes use what is called a shark screen bag that disguises the person’s shape and keeps telltale scents from reaching cruising sharks.
[Fish fact 8] The most bizarre feeding technique of all sharks is that of the Cookiecutter (cigar or luminous) shark. It attaches its mouth onto its victim and carves out a hunk of flesh, leaving a distinctive circular wound in its prey, like a pastry cutter. Its body has a series of holes called “photophores” that glow in the dark water. In fact, its scientific genus name is Isistius, from Isis, the Egyptian goddess of light.
[Fish fact 9] Jellyfish live from a few hours to many months. One species has been reported to live as long as 30 years. Jellyfish in aquariums typically live longer than those in the wild. Because jellyfish are so fragile, it’s easier for people to capture jellyfish in the polyp stage when they are the least vulnerable.
[Fish fact 10] Dreaming has been observed in bony fish, but not yet in sharks.
