There are two animals which could top the list of the most poisonous animals in the world.
The King Cobra is considered the world's most venomous snake, growing up to 5.6 m (18.5 ft) in length.

It is also called Ophiophagus which also means "snake-eater”, because it eats other snakes. One single bite of this deadly snake can easily kill a human.
This snake is even capable of killing a full-grown Asian Elephant within 3 hours if the larger animal is bitten in a vulnerable area such as the trunk.
During a bite, venom is forced through the snake's half-inch (1.25 cm) fangs into the wound, and quickly attacks the victim's central nervous system, inducing severe pain, blurred vision, vertigo, drowsiness, and paralysis. Envenomation progresses to cardiovascular collapse, and the victim falls into a coma. Death soon follows due to respiratory failure..

Its venom is not as toxic as other venomous snakes, but King Cobra is capable of injecting 5 times more venom than black mamba and can result in mortality up to 5 times faster than that of the black mamba. It is quite widespread, ranging across South and South-east Asia, living in dense highland forests.
The Box Jellyfish is also considered to be the most poisonous animal. It has causes thousands of deaths. It’s toxins attack the heart, nervous system, and skin cells.

And the worst part of it is that jelly box venom is so overpoweringly painful, that human victims go in shock, drown or die of heart failure before even reaching shore. Survivors experience pain weeks after the contact with box jellies.
Box jellyfish are distinguished by their cube-shaped medusae. Box jellyfish are known for the extremely potent venom produced by some species.
Chironex fleckeri, Carukia barnesi and Malo kingi are among the most venomous creatures in the world. Stings from these and a few other species in the class are extremely painful and sometimes fatal to humans.

Once a tentacle of the box jellyfish adheres to skin, it pumps nematocysts with venom into the skin, causing the sting and agonizing pain.

what of Marbled Cone Snail, its also very deadly. i read that one drop of its venom is so powerful that it can kill more than 20 humans.

Was hoping to see the Box Jelly fish and I did!
Its The size of your pinky but can kill an elephant!

The King Cobra is no match to the Box jellyfish!!!

islam tops the list.When those qnimals shout allau akbar the result is better imagined

Op you forgot :Marbled Cone Snail
This little beautiful looking Marbled Cone snail can be as deadly as any other animal on this list. One drop of
its venom is so powerful that it can
kill more than 20 humans. If you ever
happen to be in warm salt water
environment (where these snails are
often found) and see it, don’t even think of picking it up. Of course, the
true purpose of its venom is to catch
its prey. Symptoms of a cone snail sting can
start immediately or can be delayed
in onset for days. It results in intense
pain, swelling, numbness and tingling.
Severe cases involve muscle paralysis,
vision changes and breathing failure. There is no antivenom. However, only
about 30 human deaths have been
recorded from cone snail
envenomation.

Not the most...

Lol as in they are the deadliest and poisonous animals on earth.

if this one bite u jst start to dey repent.

The Blue-Ringed Octopus is very small, only the size of a golf ball,
but its venom is so powerful that can kill a human. Actually it
carries enough poison to kill 26 adult humans within minutes, and
there is no antidote. They are currently recognized as one of the
world’s most venomous animals.
Its painless bite may seem harmless, but the deadly neurotoxins
begin working immediately resulting in muscular weakness,
numbness, followed by a cessation and breathing and ultimately
death.
They can be found in tide pools in the Pacific Ocean, from Japan
to Australia.

Maybe Stonefish would never win a beauty contest, but it would
definitely win the top prize for being “The World Most Venomous
Fish”. Its venom causes such a severe pain that the victims of its
sting want the affected limb to be amputated. It is described as
the worst pain known to man. It is accompanied with possible
shock, paralysis, and tissue death. If not given medical attention
within a couple of hours It can be fatal to humans.
Stonefish stores its toxins in gruesome-looking spines that are
designed to hurt would-be predators.
Stonefish mostly live above the tropic of Capricorn, often found in
the shallow tropical marine waters of the Pacific and Indian
oceans, ranging from the Red Sea to the Queensland Great Barrier
Reef.

This little thing is the most poisonous on Earth!

If you ever happen to be running through the rain forests
somewhere in Central or South America, do not ever pick up
beautiful and colorful frogs – it can be the Poison Dart Frog. This
frog is probably the most poisonous animal on earth.The 2 inch
long (5cm) golden poison dart frog has enough venom to kill 10
adult humans or 20,000 mice. Only 2 micrograms of this lethal
toxin (the amount that fits on the head of a pin) is capable of
killing a human or other large mammal. They are called “dart frogs”
because indigenous Amerindians’ use of their toxic secretions to
poison the tips of their blow-darts. Poison dart frogs keep their
poison in their skins and will sicken or kill anybody who touches or
eats it.
