Superpredators

What is a Superdepredator?
A superdepredator is an
animal that dont have a
natural predator, that
means that is the highest
animal in the food chain at
least in his own habitat.

Salps
The salpidae better clown have salps are capable
of cloning himself by asexual reproduction and
become an adult in seconds,
the salps can Clone himself even 100 times to
hunt preys. The principal food of the salps is
phytoplankton, his common habitats are cold
water or near surface.
The salps are not dangerous to humans “they're
harmless”, has an expert says, it doesn´t mean
that they are not one of the most dangerous
superdepredators in his habitat and in the entire
oceanic realm.

Eel Shark
The eel shark, ruff shark or chlamys2 (Chlamydoselachus anguineus) is one of the
two extant species of sharks in the family Chlamydoselachidae, with a wide but
irregular distribution in the Atlantic and Pacific oceans, uncommonly found in the
outer continental shelf and the top of the continental slope, usually near the
bottom.
Because it exhibits several primitive features, the eel shark has often been called a
"living fossil." It reaches a length of 1.7 to 2 meters and has a dark brown, eel-like
body with the dorsal, pelvic, and anal fins set far back.
Its common name comes from the frilly or fringed appearance of the gill slits, of
which there are six pairs at the meeting of the first pair across the throat. Rarely
observed, the eel shark captures its prey by bending its body and lunging forward
like a snake. The long, extremely flexible jaws can swallow large prey, while the
number of rows of small, needle-like teeth prevent escape. It feeds mainly on
cephalopods, while consuming bony fish and other sharks.
This species is ovoviviparous: the embryos hatch from their egg capsules inside the
mother's uterus, and are maintained long-term mainly by the egg yolk. The
gestation period can be up to three and a half years

Basking Shark
The basking shark is a species of lamniform elasmobrach in
the Cetorhinidae family. It is the second largest fish in the
world, after the whale shark, and reaches 10 meters in
length and four tons in weight.
The basking shark Eat mostly crustaceans.
The basking shark is a pelagic shark that frequently visits
coastal areas, and can be found throughout the world,
from polar areas to tropical oceans, mainly on the surfaces
of continental shelves, although it prefers cold waters,
usually between 8 and 14 °C
Although it may seem like a large predator (it belongs to
the order Lamniformes, like the great white shark), its
teeth are tiny, practically vestigial, since this species feeds
passively, filtering zooplankton and small fish through its
gills, therefore what we usually see them swimming
slowly.

Sea wasp
The sea wasp is the infamous jellyfish cube developed its
fearsomely powerful poison to instantly stun or kill its prey,
it is common to see them on Oceania.
The venom of this sea wasp, is considered among the most
lethal in the world, contains toxins that attack the heart,
nervous system and skin cells.
If this jellyfish bites you, its venom is a mixture of proteins
that cause very intense pain and when spread through the
body can cause the death of a human in less than three
minutes.
They are very fast swimmers (reaching speeds of up to 5
m/s)
The power of this jellyfish is share.

Homo sapiens sapiens
The homo sapiens sapiens or human is the principal
superpredator on earth, this is because instead of the
animals, we kill and consume animals in mass.
The anatomically modern human being evolved from
me primitive Homo sapiens in the Middle Paleolithic,
about 315,000 years ago.
How does the Homo sapiens sapiens grew as a
civilization?
The Stone Age is the period that occurred, between
2,500,000 and 3,000 years a. C., and its main
characteristic is the human learning of the techniques
for the elaboration of hunting tools and stone tools.
The Ancient Age is a historical period that begins
approximately in 4000 BC. and that ends in the year
476, with the fall of Rome. Due to the creation of
writing, the Ancient Age supposes the closure of
another historical stage such as Prehistory.

In the ancient age:
• Writing emerges.
• The first legal systems collected in texts are developed.
• The monarchy holds political power.
•Agriculture is the main economic activity and the
guarantee of subsistence of the people.
The Middle Ages is the historical period between the 5th
and the 15th century. Its beginning is in the year 476, the
year of the fall of the Western Roman Empire, and its end
in 1492, the year of the “discovery” of America.
The technological advances in the middle ages were:
• Instruments for navigation
• The press
• The Clock
• Glass Windows
• Optic Instruments
• Useful for distillation
In the modern age it is understood from the year 1492 to
the year 1789 and technological advances were created
such as: the compass, cartography and firearms.
I

In the contemporary age, one of the most important
events for humanity occurred. The industrial
revolution which changed how we generate energy
we switched to fossil fuels like oil which we get from
the depths of the earth. In the sea there are oil
platforms that extract oil for a long time and there
may be spills that can kill thousands of aquatic
species.
The increase in population during this age caused a
greater demand for direct products from sea animals
and therefore overfishing. Humans have
extinguished more aquatic species in recent years
than in the last 2000 years due to direct damage to
the sea, lakes and rivers and not direct damage to
the entire environment of the planet.
