… That there are more than 465 known species of sharks living in our oceans today?
Sharks belong to a family of fish that have skeletons made of cartilage, a tissue more flexible and lighter than bone. They breathe through a series of five to seven gill slits located on either side of their bodies. All sharks have multiple rows of teeth, and while they lose teeth on a regular basis, new teeth continue to grow in and replace those they lose.
Shark ‘skin’ is made up of a series of scales that act as an outer skeleton for easy movement and for saving energy in the water. The upper side of a shark is generally dark to blend in with the water from above and their undersides are white or lighter colored to blend in with the lighter surface of the sea from below. This helps to camouflage them from predators and prey.
They also predate Dinosaurs by 200 million years. The largest known species of shark, Carcharodon megalodon, might have reached a maximum length of over 20 meters (67feet).

I stay out of the water because of these. I’m afraid they will take one look at me and think “Ooooo … corn fed … nom nom nom”

Living in FL, I have always wondered in the back of my mind how close they are when swimming in the ocean.

Your waters are cold? I always thought Australian waters were as warm as Australia. Perhaps I think all of Australia as the desert of the Outback.

Further up it’s warm. Not here in Victoria, South Australia and Tasmania.

I must say that reading about sharks this morning was a pleasant diversion from reading about the RNC. Thank you!

This is exactly why I don’t go into the ocean. There are way too many eating machines in there with lots of rows of sharp teeth that would make a meal of me!
