Dead shark washed ashore on the Libyan coast with an 11-inch ‘blade’ trapped in the back of a 6-foot swordfish
- A dead shark found on a beach in Libya was killed by a swordfish
- An 11-inch male, swordfish nose, was pulled back from the shark
- Experts said the attack occurred about three days before the body was found
- They believe the incident was a random collision and not a full blown attack
Swordfish are predatory fish that attack sharks and a recent discovery on a beach in Libya shows just how lethal this creature can be.
A new study describes a dead female shark found on a coast near the town of Brega, dying from a piercing trauma of the swordfish skin.
One resident spotted the lifeless shark at the end of the beach and pulled an 11.8-inch blade from its back that is believed to have pierced the shark’s heart.
Citizen scientists, who performed the gruesome spectacle, assumed the swordfish was about 6 feet long and attacked the shark from behind three days before it washed ashore.

A new study describes a dead female shark found on a coast near the town of Brega, dying from a piercing injury to the swordfish’s skin.
Research published in the journal Ichthyological Research said that the drum belonged to the swordfish Xiphias happyius, ‘a highly mobile predatory fish that is both capable of attacking sharks, whales, humans and even ships. . ‘
Such attacks have been recorded since the 1960s, but recent discoveries provide the first example of swordfish mortality.
The dam shark was only a little over 14 feet long when the ‘Marine Life in Libya’ citizen science initiative arrived on the scene.
There was no immediate clue as to how the shark died, but when they took a closer look, the team discovered a hole in its back.
Citizen scientists, who performed the gruesome spectacle, claimed that the swordfish was about 6 feet long and attacked the shark from behind three days before it washed ashore.
Based on the position of the blade, the team believes that the shark was injured at or near the bronchial apparatus of the vertebrae resulting in damage to the nerves and arteries, along with its gill arch.
The skin membrane penetrates the shark at an angle of about 70 degrees from the front-rear axle, towards the bronchial apparatus, reveals that the swordfish must be located from the shark’s back and stab it. from behind, ‘research writes.
Based on the position of the blade, the team believes that the shark was injured at or near the bronchial apparatus of the spine resulting in damage to the nerves and arteries, along with its gill arch.
Wounds are also thought to have occurred within 3 days of the shark’s discovery, as the wound has not healed and the blood is still pink in color.
Researchers shared during the study: ‘This color faded on the day of the second test three days later.
‘The location of the wound, the duration of the wound and the lack of other obvious injuries lead us to the conclusion that the stab was fatal and the ultimate cause of death for the pounding shark.’
The team notes that most shark attacks are done by juvenile fry, but the long-tailed shark is an adult and is roughly the same size as swordfish.
The team noted that most shark attacks are performed by juvenile fry, but the dam shark is an adult and is roughly the size of swordfish.
“ The swordfish participating in the current attack is not the juvenile, but is roughly the same size as the thumping shark and therefore, not in line with its hunting spectrum, which makes for a great deal. attack as a defensive response is unlikely, ” the newspaper said.
With this in mind, the team speculates the attack could have been accidental – the two might have eaten the same prey.
But that may be how the swordfish tries to keep the shark away from the meal.
