Friday, oh friday...how I love you. I miss you when you are away.... okay okay, so its friday 3pm and I've really checked out. Its so hard to work when it is literally perfect outside. I'm trying, nonetheless, to get some stuff done in advance for once.
So for the sake of random facts...
- SHARKS don't have any bones, the skeleton is made up of cartilage
- Swell sharks can bark like dogs do
- Sharks can have from 6-12 babies at a time, but the hammerhead and tiger shark can do up to 40
- When it comes time to give birth, the female shark loses her appetite so she won’t be tempted to eat her own pups.
- They can swim from 20-40 mph
- The While shark is the biggest fish in the world
- Sharks have been around 450 million years. They lived before land vertebrates populated the earth
- As teeth are ground down or they fall out, new ones from the other rows come forward to fill the slot. This continues for their entire lives.
- The smallest shark is the Dwarf Lantern Shark - 7 inches long
- Sharks do sleep, but they do so with their eyes open. Only one side of the brain sleeps at a time so that they are able to continue the cycle of taking in air as they rest.
- Because sharks very rarely get cancer, scientists study their cartilage in the hopes of finding a cure for the disease
- Sharks can grow more than 20,000 teeth in a lifetime
- 90% of shark attacks have happened to men.
- For every human killed by a shark, humans kill two million sharks
