Fact of the Day: Shark Babies

Since sharks have existed for many eras of the Earth, there have been countless species of sharks. Some species reproduce much differently that others. Some sharks give birth to live young, while others lay eggs that hatch later.

  1. Interesting but sharks live in the oceans and people who want to swim at beaches should observe signs of when/where to swim.
    I have no sympathy for idiots who get bitten or killed.
    They all break the laws of surfing. I was a Life Saver on a Sydney beach when I was a student at college and university.

    1. How clever you are?
      I wonder if sharks are in Lake Ontario? Bit difficult I would think coming up the locks of the St.Lawrence river, eh?????
      Pity the city of Toronto and especially your suburb didn't take a move across the Lake to Buffalo or Rochester - two other cities I have stayed in and enjoyed with US friends who had intelligence.
      Then again the residents of Buffalo and Rochester, may have legitimate reasons to object.
      I don't think PM Justin Pierre James Trudeau would really mind.

    2. the biggest thing that separates mammals from other animals is being fed milk by it's mother. Live birth and warm-blooded tends to follow too.

      Though there's always exceptions to the rule. Like the good ol' platypus.

      The only true thing that makes a living thing a mammal is common ancestry from the first true mammal species.

    3. Ah the Aussie little fellow.
      Not to be played with - they have poisonous spurs in their webbed feet. Deadly!

  3. We're getting too many cases of shark sightings and bites around here. It makes me nervous.

    1. Well Kay - swim between the flags and listen to the life guards - quite simple really.

  4. That's interesting to know. I thought all sharks gave birth to live offspring. Learn something new everyday.

  5. We just watched the original Jaws the other night and explained to our 15 year old how scary and awesome those special effects were in 1975. Hahaha

  7. Unlike humans who have evolved beyond recognition in the past five million years, nature has deemed the design of the shark so perfect that it hasn't changed in 500 million years.

  8. When I think of sharks, I think of the poor people who've been stranded on lifeboats in the ocean, and how sharks would bump against the bottoms of their rafts. Eddie Rickenbacker has an amazing story.
