Bible
\n<\/strong>We read from "God and Me": 365 Daily Devotionals.  We read from Genesis 1:11-13 about the plants and caring for them.<\/p>\n

Zoobook: Sharks<\/strong><\/p>\n

New things we learned today:<\/p>\n

– Carnivore- eats meat<\/p>\n

-The Caudal Fin is the tail fin that propels the shark forward.  Sharks can swim up to 40mph.<\/p>\n

-Sharks have slits on the side called gills. <\/em> The gills filter oxygen from water for breathing.<\/p>\n

-Fish have swim bladders <\/em>that can be filled with oxygen or a gas to allow the fish to float, but sharks do not have this and most must constantly swim or they will sink.  Some can rest on the ocean floor or on a rock, while others engage in a sleep-swim<\/em> state, but sharks do not sleep like humans do.<\/p>\n

-The Pectoral fins are the two fins on the sharks chest.  These help the shark ascend or descend.<\/p>\n

-The shark is a predator.  <\/em>They hunt for their food, the prey<\/em>.<\/p>\n

–Ampullae of Lorenzini<\/em>– the small holes below the shark’s nose and chin that detect electrical impulses coming from all living beings.<\/p>\n

–Lateral Line<\/em>– A lateral row of holes along the sharks sides that helps sharks to sense all activity around them.<\/p>\n

-up to 2\/3 of the shark’s brain focuses on smell.<\/p>\n

–Feeding Frenzy<\/em>– A bunch of sharks will suddenly bite anything in sight, including themselves and each other.<\/p>\n

-Sharks don’t chew; they swallow items whole.<\/p>\n

–Remoras<\/em> are fish that will keep the shark clean in exchange for bits of the sharks food.<\/p>\n

–Thresher Sharks-<\/em>Have a tail up to 10 feet long (or half it’s body length) that can be used to herd fish for feeding or used as a bat to stun their prey.
\n\"\"<\/p>\n

 <\/p>\n

–Nurse Sharks<\/em> can give live birth to 20-30 pups at a time, each about one foot long.<\/p>\n

\"\"<\/p>\n

–Tiger Sharks<\/em> can have up to 80 pups at a time!  They are usuall 4.5 feet long.\n<\/p>\n

\"\"
\n-The largest organ on a shark is their liver.  <\/em>It can be up to 25% of the sharks body weight.  It is typically full of oil used for vitamins, makeup, and paint base.<\/p>\n

-Sharks HATE the Moses Sole<\/em>.  If they bite one, a chemical is released, and they will spit the fish out.  Scientists are trying to recreate this chemical as a shark deterrent for humans.\n<\/p>\n

\"\"<\/p>\n

-Sharks also hate the Pufferfish<\/em>, for obvious reasons.  A shark can die if the Pufferfish blows up in its throat.\n<\/p>\n

\"\"<\/p>\n

-Sharks are not too picky about what they will eat.  these items have been found in the belly of a shark:<\/p>\n
