Sea Turtle Escapes the Jaws of a Shark Attack

Sea turtles are less slow and steady than we have historically assumed. On the Ningaloo Coast of Australia, a photographer captured a heroic fight between a sea turtle and a tiger shark.

June 22, 2022

Within the captured video, this determined sea turtle rapidly swims to avoid the tiger shark’s jaws and flips over several times to evade capture. The tiger shark eventually gets its jaws close to the sea turtle’s protective shell but does not manage to fully latch onto its prey. The tiger shark finally looks as though it is succeeding but the turtle flips once again to escape the predator. The photographer noted that he observed the turtle land on shore and survive the attack.

In this David & Goliath type fight, many would assume that the sea turtle would meet its demise but its tactful evasion shows the wonderful defensive tactics that sea turtles have. Fully mature sea turtles have very few predators including killer whales and large sharks. With lifespans ranging from 40 to 60 years old, it’s no wonder why they must adapt their defense mechanisms to survive.

In the wild, sea turtles’ defense mechanisms are hard to observe due to the depleting shark populations around the world, the captured video provides a unique glimpse into sea turtles' tactics. Some studies suggest that sea turtles' u-shaped diving functions as both a resting dive and a way to scan the ocean’s surface for predators before coming to the surface. Their trademark hard shell helps defend their other more sensitive tissues from oncoming attacks. When protecting itself from predatory attacks, the sea turtle will strategically turn their shell in the direction of a shark’s mouth to prevent a bite of its flippers or softer parts and will rapidly swim in the opposite direction to avoid being caught. This species’ built-in defense helps them protect themselves against one of the most prolific predators in the ocean.

The Jaws Boat is Being Rebuilt, But This Time to Save Sharks

‘The ORCA’ may just be the most famous boat in the film industry. Immortalized by the thriller Jaws in 1975, the vessel relentlessly pursued the 25-foot, three ton-big shark. However a new reincarnation of the old classic boat will take on a new goal: to save sharks, not hunt them.

Shark Conservation is Essential to Tackle Climate Change

We depend on sharks: that’s just a fact. As predators, they regulate the ocean’s ecosystems and reduce carbon emissions, so preserving their numbers is a top priority.

Baby Sharks are in Hot Water

Climate change impacts everything. From rising ocean levels to record-breaking wildfires, we can see the changes occurring with our own eyes. One of the most resilient species of all time is the shark. Warming waters are challenging their ability to adapt, and one of the signs of the times is smaller baby sharks that are having a hard time surviving.
