Over the weekend I had the pleasure of helping one of my grandchildren with a school project. What was great about this project and also made it more interesting for me, was the fact that it was based on a type of fish we find swimming in the oceans of the world. Although it is not a fish like that of a bass, trout, or even a tuna it is by far one of the most fascinating creatures that lives in any body of water. If you guessed Shark you are absolutely right!! Helping my grandson Grant with his project even taught me some fascinating facts that I didn’t really know up until now! So I thought I would dedicate this post to the hard work that Grant did for this project and also to promote the fact that spending time with a child helping to grow whatever interest may be festering inside them is priceless. With Grant the fact that he too is interested in fish opens up a bonding that hopefully we can share together and will allow me to teach him all I know when it comes to the waters that fish live in as well as about different fish themselves.
The first interesting fact we learned is that Sharks can have shark babies also known as pups in a couple different ways. How sharks have their babies differs on what type of shark it is.. Some sharks can have 1-100 shark pups if they lay their eggs and the sharks hatch outside of the mother. Other sharks keep their eggs inside and the shark pups hatch inside their mothers and then are delivered. One thing that is the same for both however is that sharks do not care for their babies after they are born. Instead they find a safe place and either lay their eggs or leave the newly delivered shark babies to fend for themselves.
The next interesting fact that Grant and I learned was that sharks use ⅔ thirds of their brains for smell. Because they have such a heightened sense of smell they are one of the ocean’s top predators. However although sharks are dangerous and we do hear of shark attacks happening, there are only about 100 that happen every year. Only 10 of those result in the death of a human.
Sharks often eat alone and even will sometimes eat other sharks! They can go through and use up to 20,000 teeth in their lifetime. They also are the only animal or mammal for that matter on the planet that both the upper and lower jaws move. They have the most powerful jaws around and the size and shape of their teeth depend on the type of shark they are.
There are so many more interesting facts I could share with you about sharks, Grant and I learned a lot. I think I may have had a better time then he did with his school report. Fish and grandchildren, you ask me it doesn’t get much better then that. Willamette let you go…lol, until next time my friends!
