Dryococelus australis The Extinct Insect Which Came Back To Life
Have
a look of the rarest insect in the world… It has been hidden for 80
years, and its name is Dryococelus australis, or the Land Lobster.
Despite the fact that it was considered completely extinct, a team of
scientists discovered that this rare insect is still alive on Lord Howe
Island.
This phenomenon is known as the Lazarus effect, and even though it’s been rediscovered, the gigantic insect is still the rarest one on Earth. Only 24 specimens have been discovered, and by the looks of things, it may go back to its extinct status if extreme measures aren’t taken soon.
Dryococelus
australis has been rediscovered on this remote island named Ball’s
Pyramid, which is a remnant of a shield volcano that formed about 7
million years ago. It is 562 meters tall and 1,100 meters (3,600 ft) in
length, and it’s a wonder that the insect was discovered in such a small
habitat.
The
eight-legged giant insect had literally disappeared off the face of the
Earth back in 1920 from their very own habitat in the Lord Howe Island.
This rare insect was endemic to that area (they only lived in that
area). But why do you think they disappeared? Well, as usual, humans had
something to do with it.
In 1916
people knew that on Lord Howe Island there lived a humongous insect, one
as big as the human hand… it looked like a stick which gave it a great
advantage of camouflaging as a piece of wood on any tree. The insect was
so huge that the locals dubbed it “land lobster” or “tree lobster”. The
giant bug was 12 centimeters long and the heaviest (but flightless)
stick insect in the world.
There
was a time when local fishermen used to hang them on their hooks and
use them as bait in order to catch big fish. So if there were so many
specimens that people could use them as bait, what on Earth went wrong?
One
dark and gloomy day in 1918 a cargo ship from Great Britain washed
ashore on Lord Howe Island and it had to be completely evacuated in
order for the repair team to fix the ship. Along with the eviction of
human, the rodents on board also found their way on to the island.
All aboard!
When
the boat was fixed the people got back on board, unaware of the
disaster they had caused. The rats settled in the island and found a
great source of proteins in the form of the gigantic land lobsters
(thinking like Bear Grylls before it was cool). In just two years, the
island was full of rats who had practically devoured the entire colony
of insects.
By 1920, no one had seen
the insect anywhere on the island, and in 1960 it was already considered
extinct… but rumor had it that some adventurous rock climbers had
spotted the remains of some stick insects which seemed recently dead.
Now the problem with this rumor is the fact that the “extinct” insect is
a nocturnal being, and no one was brave enough to venture on to the
rocks at night.
The
brave expedition wasn’t until 2001 when a team of scientists who dared
to climb the 500 feet rock during the night with flashlights and
cameras. Luckily, their efforts were not in vain, they discovered 24
specimens of one of the largest insect in the world. Their exact words
were:
“It felt like stepping back into the Jurassic age, when insects ruled the world.”
After
this amazing discovery was made, the it took the officials two years to
make up their minds as to what should be done to preserve this species.
Eventually, they decided to take just four insects in an attempt to
breed them.
One
pair died, but the other two were named Adam and Eve, and were handed
to the Melbourne Zoo and placed with Patrick Honan, who managed to
successfully breed the insects, hence creating a new population of
Dryococelus australis.
They even made a
video of the amazing hatching of baby insects. It seems that in this
case, were able to repair a mistake of our ancestors, hopefully, we will
realize that we have many more endangered animals living on Earth, and
if we don’t act now, our kids might be reading about them in books and
atlases. Have a look below to see how these amazing insects hatch from
their eggs.
