Shark Week 2017: Closing Down..



This was my list of the week’s activities..what to draw, what to research..some things I passed on in order to do them next year. And I still made sure I remembered friends’ birthdays!

I learned so much this week! Of the main things I can remember:

  1. There are both endothermic and exothermic sharks.
    The endothermics are a small group of sharks called the Laminids, and they have evolved the ability to maintain their body temperature a few degrees higher than their environment,rather than their body consistently staying the temperature of their surroundings. This group includes the great white shark, salmon, mako, and porbeagle sharks.
  2. Not all sharks have to keep moving to keep oxygen flowing to their gills.
    Some species,like the whitetip reef shark, can pump water over their gills by opening and closing their mouths while resting. For this reason they can stay hidden in caves.
  3. Sharks can not only hear, they have inner ears.
    A shark’s sense of hearing is,actually its strongest sense. Sharks can hear sounds up to a kilometer away or more.
  4. Species I learned about for the first time:
    Galapagos Shark, Pajama Shark, Copper Shark,and Porbeagle.
  5. There are nine different species of Hammerheads:
    • Winghead Shark
    • Scalloped Bonnethead
    • Whitefin Hammerhead
    • Scalloped Hammerhead
    • Scoophead
    • Great Hammerhead
    • Bonnethead
    • Smalleye Hammerhead
    • Smooth Hammerhead
  6. The Great Hammerhead is inclined frequent cannibalism.
    Because of their smaller mouths, Hammerheads are often hunt along the bottom for rays, shrimps, squids, small fish, and even other shark species. They use their heads to stamp down rays.
  7. Scientists have studied the body language of Great White Sharks .
    Studies have revealed various movements such as lateral display, parallel swim, gaping, and hunching, that help sharks communicate with each other in areas of rank and dominance to avoid all-out fighting. Some movements, such as gaping, simply are about possibly releasing frustration.

There were plenty of other new points I learned, but those stood out the most. Well, until next year, my friends,
