[Science fact 1] There are two kinds of crabs. First are true crabs, or brachyurans, which have a very short abdomen and use four pairs of long legs for walking. True crabs include blue crabs, spider crabs, and ghost crabs. Second are false crabs, or anomurans, which have a longer abdominal section and fewer walking legs. False crabs include hermit crabs, king crabs, and squat lobsters.
[Science fact 2] It has been found that human evolution solved the same problems in different ways throughout history in different tribes. Native Early peoples adapted to high altitudes differently: In the Andes, their hearts got stronger and in Tibet, their blood carries oxygen more efficiently.
[Science fact 3] There is a gemstone called Alexandrite, that will change colors, usually from green to red, based on whether it's viewed under natural or artificial light.
[Science fact 4] There are "lone planets" that roam endlessly through space without ever going into orbit. They are actually predicted to be more common than stars. Scientists believe these lone worlds were probably ejected from developing planetary systems.
[Science fact 5] Empty dogfish egg cases sometimes wash up onto the beach. Some people call them mermaid purses.
[Science fact 6] The first ice cream truck vendor in the United States was Harry Burt, who started his business in 1920.
[Science fact 7] Humans stand little chance of surviving a shark attack. One of the most startling incidents of a shark attack occurred in Tasmania, Australia, in 1993. Terri Cartwright died instantly when a 15-foot Great White bit her in half as her horrified family watched from a boat. She was last seen in its mouth. Part of her leg and a piece of her wet suit were later found.
[Science fact 8] Ice cream consumption increased dramatically during prohibition, as many breweries switched to making ice cream.
[Science fact 9] Jellyfish are usually seen in shallow coastal water; however, scientists have discovered a few species that live at depths of 30,000 feet (9,000 meters). While most jellyfish prefer warm water, some live in subarctic temperatures.
[Science fact 10] The first use of the word “shark” in English occurred in 1569. Previously, English sailors and fishermen used the term “sea dog” or the Spanish tiburón. It could possibly be from the German Schorck, which is a variant of Schurke (“scoundrel villain”) from shürgen (“to poke, stir”).
