Hi Guys & Girls,
So, you may be wondering why there was a period of extended absence from last week followed by a post everyday? The absence last week was of course down to family issues, it’s been a rough 9 months and finding time to write has been tough. As for why a post a day? It’s Shark Week!!!!
So far my posts have been about fitness and TV. But what about the creatures themselves? Sharks are my favourite creatures on the planet. They aren’t the cutest, the most cuddly or nicest but to me, they are amazing.
Sharks get a bad wrap. The Jaws film series and Deep Blue Sea have a lot to answer for! Here’s the thing though, if I entered a lions domain, I’d expect to get mauled!
I’m gonna give you five of my favourite facts about Sharks…
1. Extinction Events? Bring it On!
Sharks are one of the oldest creatures on the planet. In some form or another, sharks have existed for over 400 million years. They have survived MULTIPLE mass extinction events. The extinction events killed most life on the planet and yet Sharks remain. The last mass extinction event was of course 65 million years ago and it wiped out the dinosaurs.
2. She’s a Man Eater? Yeah Right!
The mere word, “Shark”, conjures up images of the apex predators. The Great White Shark, The Hammerhead Shark, Tiger Sharks, Mako Sharks, etc. Scary stuff right? After all, they are top of their respective food chains.
These bad boys are responsible for some gruesome injuries and of course, deaths to humans. But are sharks really that deadly to humans? These innocuous items or creatures are responsible for more deaths per year than the “deadly”, “man eating”, “predators”…
3. They Are ALL Mindless Man Killers, Right?
Wrong! There are more than 500 species of shark. Ranging from the tiny Dwarf Lantershark which reaches around 21 centimeters, all the way up to the huge Whale Shark, which can reach up to 60 foot long.
Oddly enough, the largest species of shark are also gentle giants and tend to feed on mostly plankton. So, of these 500 species of shark, how many can be deadly? Around 3%…
4. My Spidey Sense is Tingling
A shark has ridiculously heightened senses. It’s widely accepted that a shark can sense blood in the water. For example, at the end of the film Deep Blue Sea, the genetically modified Maiko shark was trying to escape the facility… until she sensed Saffron Burrows jumping into the water with a cut.
A Great White Shark can sense one drop of blood in 25 gallons or 100 litres of water. They can also sense that drop from 3 miles away. To give you an indication on how their senses affect you, if you go to an aquarium and go near the Black Tipped Reef Shark, they can “smell” what you ate for lunch.
5. Top Of The Food Chain? Perhaps Not…
As I said in point 3, the apex predators are top of their respective food chains. The problem is, the biggest threat to sharks is in fact us. We have hunted some of them to the brink of extinction. Couple that hunting with the fishing industry grabbing up tonnes of sharks on a regular basis and you have a recipe for disaster.
For example, the Whale Shark doesn’t reach sexual maturity until it’s 30 years old. The likelihood is, the ones we have fished accidentally, have not bred.
This is why stories like the “Deep Blue” story are extremely good news for shark fans. Deep Blue is supposedly the largest Great White Shark ever filmed. She was estimated at 50 years old. Check her out here. She’s a beaut!
If you’ve reached the end of my shark Activist post and haven’t gotten bored, I salute you! Please tell me what your favourite animal is and why…
Carpe Diem Guys
