Videos: Strategies Used by Sea Turtles to Avoid Being Eaten by Tiger Sharks

Did you ever wonder how we have any sea turtles left in our oceans?  Surely as the years have passed these slow moving tasty morsels of goodness would have nearly all be consumed by the the more agile and powerful shark. I mean really, other than a hard shell (which tiger sharks have little problem sawing through with their well suited teeth), what chance do sea turtles have?

Well it turns out, sea turtles have some clever defenses that it can use to help avoid being taken by a shark.

Firstly, when approached by an inquiring shark, the sea turtle will often present it’s full, flat shell towards the shark.  Instead of being horizontal like a flat cookie which the shark can easily bite through, it will stay in a half-roll type position and the shark will not be able to open it’s mouth wide enough to bite into the large broad surface of the shell.

Secondly, the turtle will stay very close to the shark and will keep swimming in a tight circle around the shark.  The shark will not be able to match the tight radius and thus will not be able to latch onto the turtle.

Earlier this week, Tom Caska from Sydney Australia, fired up his phantom drone to capture some aerial shots of his brother Andrew Caska who was paddleboarding with friends.  They were boarding about 50 meters off shore at Kilcare, which is about 30 nautical miles north of Sydney in New South Wales, when Tom captured this stunning image at around 5:30pm in the evening.

Tom believes that the shark is a great white and estimates its size at around 4 meters (13 foot) but noted it is hard to judge as he had a fish eye lens on his Go Pro camera.  For comparison, his brother Andrew is 6′ 2″ and is on a 9′ 6″ board (Andrew is on the red paddleboard).  The person closest to the shark is on 6 and a half foot surf board.

Tom told us that at this time of year, great whites are migrating south and it is common for them to be spotted in the area.  As you can see in the photo, this shark looks to be in pursuit of a small school of fish which Tom believes to be salmon.

His brother never spotted the shark and only saw a bit of swirl in the water.  It wasn’t until Tom later showed him the photo that his brother learned what photobombed his pic.

Tom is starting up a drone photography business, Aerolens, and he can be reached at info@aerolens.com.au for any inquiries.

Great White Attacks Boat Carrying Shark Fishermen in South Africa

In an odd turn of events, the iafrica.com news agency is reporting that a great white shark attacked a small boat carrying fisherman who were out to fish for smooth hound sharks.

According to the report, the inflatable boat was about three miles off the coast of Strandfontein when the attack occurred.

The great white was latched on the boat for about sixty seconds and when it let go, the boat had  a large gash with a few embedded teeth.

The crew of the boat immediately headed for shore and all aboard safely arrived.
