Animals and the Environment.

This term Narwhals class will be finding out about animals and their environments.  Each week Mr Burns will be posting something for the class to look at and comment on.

This week why not look at this link?

Also, Mr Burns would like all of Narwhals class to try and find out why Narwhals have a horn.  Research this very difficult question and blog back what you’ve found out in time for next weeks lesson.

    The narwhal tusk in males is essentially for show.

    Hello, it’s me josh. I realy like narwals. It is an nice name for our class. Anyway we are thinking what is the horn for the narwhal well I think that it is for so it could get it prey by getting their horn and get their pray. So here is some information from a site:The narwhal has a tooth, or tusk, which emerges from the left side of the upper jaw and is an evolutionary mystery that defies many of the known principles of mammalian teeth. The tooth’s unique spiral, the degree of its asymmetry to the left side, and its odd distribution among most males and some females are all unique expressions of teeth in mammals. The narwhal is usually 13 to 15 feet in length and weighs between 2,200 and 3,500 pounds. Its natural habitat is the Atlantic portion of the Arctic Ocean, concentrating in the Canadian High Arctic: Baffin Bay, Davis Strait, and northern Hudson Bay. It is also found in less numbers in the Greenland Sea, extending to Svalbard to Severnaya Zemlya off the coast of Russia.

  8. EleanorW narwhal class says:

    HI I think narwhals have a horn so they can attract
    females.
    I allso think they have a horn so thay can fight
    other males!

  9. George says:

    The horn is actually a tooth that has grown rally long. The tooth can grow up to 5 meters long.

    They use it to comunicate with other Narwhas and it carrys a blood vessle inside it.

  10. Matthew says:

    Hi I like narwhals and im going to tell you some facts about them.Female narwhals don’t have horns so it’s hard to protect themselfs and the narwhals horn is the only straight tusk in the world, plus they can grow up to 9 feet long.A narwhals tusk is very flexible and bend a foot in any direction without the horn breaking.The narwhals horn is the left tooth that has grown through the lip and came out of its head,and sometimes you can find double horned narwhals because the right tooth has grown as well.The narwhals use their horn to break ice and some fight with the horns,sometimes they use it to catch fish.Well thats all I can give you.

  11. Matthew says:

    Hi it s me again.Since you looking for facts on narwhal horns i’ll tell you about rhino horns. Rhinos use their horns to protect themselfs and in aisa rhinos have two horns, one small one at the back and one on the front. when they charge they lower their head and CHARGE!!!!

  12. Matthew says:

    OK this is the last time but did you know a narwhals horn is made of ivory.

  13. Anonymous says:

    so if a Nawall is swimming and anoghther animal want’s to eat it then it can save it’s self with it’s horn.Ellie l.

  14. katie says:

    A narwhal haves a horn because it helps them to survive and if they don’t have a horn they wouldn’t survive as long half the time the website says.

  15. Isabella says:

    The Narwhal is the unicorn of the sea.These mammals have two teeth.
    The boy Narwhal has a more prominent tooth that looks like a tusk.They fight with it.Also, the boys show off with the tusk to impress the girls.
    The tusk tooth grows right through the Narwhals upper lip.
    The tusk can grow up to 8.8 feet(2.7 metres)long.
    The girl Narwhal has a smaller tusk.

  16. stan says:

    why Narwhals have a horn?
    to tap at the ise to see if the braik frew the ise.To brev
    becos they are mamls and haf to hold ther breth.

  17. jacob says:

    The reson narwhal’s have a tusk never known.One theory is they used them for fighting in
    duels.

  18. Daisy says:

    Scientists are not sure why a narwal has a tusk,some believe it is to attract a females attension, or to fight.

    Facts:

    1.It is a ivory tooth [not a tusk or a horn.]
    2.The tooth can grow up to 2.7 meters
    3.The ivory tooth grows right up through the narwals upper lip.
    4.A female can grow a tooth but it dosn’t grow as prominent as the males.

  19. saskia says:

    Hi Mr Burns ,
    the narwhals tusk is a tooth.Its tusk grows in a hole in its upper lip. Narwhals have it for:-
    -Breaking ice
    -Spearing fish
    -Piercing ships
    -Transmitting sound
    -Shedding body heat
    -Poking the sea bed for food
    -Attracting females
    -Defending baby narwhal

    So now you know !!!!!!!!!!!!!

  20. Mia f yr4 says:

    Sinetests have found out that they have Special blood vessels in there tusks as well they help them survive. They use them to fight as.

  21. GEORGIA says:

    Hi Mr Burns
    Narwhals have tusks because they are filled with sensory nerves, up to 10 million or so. much more than us! This helps the Narwhals with information about water temperatures and water pressures of the sea. Also Narwhals have horns to help find their prey, but not all narwhals have tusks, which must mean it is not essential.

    In London last weekend I visited the national history museum and I got to feel a Narwhals tusk!!!

  22. NUALA says:

    I THINK THAT NARWHALS KNOCK OUT THEIR PREDATORS WITH THEIR HORN .

    Hi Mr Burns

Much more than our sensory nerves! this helps the narwhals with information about water temperatures and water pressures of the sea. They also help the narwhals find their prey, but not all narwhals have tusks, which must mean it is not essential for feeding as they would all have tusks!

    I visited the National History Museum in London last weekend when we visited for my birthday. I held a narwhals tusk!!!

  24. anna says:

    I have found out the tusk is the whale’s left upper incisor tooth, and grows forward, spiraling around to form a pointed lance about 2 meters long.

  25. marianelmore says:

    narwhals have a very long nose they eat small fish and plancton.they can grow up to nine feet long they also have a tusk which they use to break the ice.they also use their tusks to show off to the female narwhals. by gabby hahn.

  26. Amber says:

    Narwhal tusks are filled with nerves and tell the whale about the water temperature and pressure. They may help the narwhals navigate and find prey. I found this on http://www.sciencemadecool.com/2005/12/why_do_narwhals.html
