Scientists are stunned when a terrifying deep-sea predator with a "snake-like head" reappears after 80 million years!
the dinosaur era has recently discovered. It has hardly changed in 80 million years, with a body resembling a serpent
and hundreds of sharp fangs. This creepy monster, which was pulled from 700 meters below the surface,
is still a mystery to science.

Off the coast of Portugal, scientists have discovered a unique discovery:
a frilled shark, a species that has not altered much in 80 million years,
was unintentionally captured during a commercial fishing operation. With its articulating jaw, 300 needle-like teeth,
and serpentine body, this elusive predator provides insight into
the most enigmatic creatures of the deep ocean.
A long-extinct creature hiding in the depths
During a study supported by the European Union to lessen unintentional bycatch,
the frilled shark was hauled up from 700 meters below the surface. Because it has not changed much since the dinosaur era, this 1.5-meter
deep-sea predator is regarded as a "living fossil."
With its slim, eel-like physique that enables it to glide
stealthily in the ocean's depths, the shark is named for the gill structures
that resemble frills around its throat. Its rows of backward-facing teeth
are used to catch prey that has little chance of escaping, and it mostly
hunts fish and squid.
Specialized adaptations for survival in the deep sea
The frilled shark is said to employ an ambush strategy, lunging for unwary prey in
Although the frilled shark is found all over the world, it is rarely seen in
its native environment because it usually lives 500–1,000 meters below the surface. Its behavior, population size, and chances of long-term survival
are still mostly unknown to scientists.
In 2007, Australia recorded one of the few recorded captures of a live frilled shark,
although the specimen did not survive long after it was brought to the surface. These encounters are extremely unusual, according to researchers, because these
the deep sea's darkness, in contrast to contemporary sharks that depend on strong,
swift attacks. Its thin form permits it to maneuver through confined crevices where prey may hide,
and its incredibly flexible mouth allows it to swallow enormous fish whole.
Its reproductive cycle is another peculiarity; according to scientists, frilled sharks
have one of the longest gestation durations of any vertebrate, up to 3.5 years. Although a mother can have anywhere from two to fifteen children, the species
is susceptible to changes in its surroundings because of its sluggish
reproductive process.
Is the species endangered by deep-sea fishing?
Although the International Union for Conservation of Nature (IUCN) does
not officially consider the frilled shark endangered, growing deep-sea
fishing activity raises the possibility of unintentional catches. Researchers caution that these sharks might be more vulnerable than previously
believed because they have a poor rate of reproduction and live in uncharted
areas of the ocean.
The necessity of ongoing deep-sea exploration
is highlighted by this most recent revelation. Animals like the frilled shark serve as a reminder that Earth still harbors mysteries
from its prehistoric past, and the world's oceans are still mostly uncharted. But how long will these prehistoric predators survive in the deep water given
the increasing human activity there?
