The World's Most Poisonous Deadly Animals


The above image shows the most venomous and poisonous animals in the world. Some of them can look innocent but has the power of instant death for people and other animals. I have compiled some information for each deadly monster.

Box Jellyfish

It lives in the oceans of Asia and Australia. Swimmers must definitely avoid the Box jellyfish. The stingers and tentacles on this animal are extremely powerful. Along with causing excruciating pain for weeks, the animal's venom is capable of stopping the heart or paralyzing the lungs. To top it off, the venom will slowly eat away at the skin.

Marbled Cone Snail

The venom of this tiny snail leads to paralysis almost immediately. Humans that have experienced a bite are succumbed by weakness, numbness, nausea and death, when the lungs ultimately stop working.

Blue Ringed Octopus

The painless bite from a Blue Ringed Octopus may seem innocuous, however the deadly neurotoxins in the animals saliva immediately begin working. Within a few minutes, a human will experience muscular weakness, numbness, followed by a cessation and breathing and ultimately death

Death Stalker Scorpion

The venom of the scorpion causes an intense and unbearable pain, then fever, followed by coma, convulsions, paralysis and death. Living area is North Africa and Middle East.

Stonefish

Highly camouflaged fish living in the waters of the Pacific throughout the Australia coast.
If contact comes with humans, the venom will cause intense pain, swelling of tissue, shock followed by death.

Sydney Funnel Web Spider
One of the most venomous creatures in the Australia outback, the Sydney Funnel Web Spider packs a powerful punch. This spider is large and very aggressive, consistently creating the most powerful venom of any spider. Protecting its burrow, the spider places a web across its entrance that passers by should not enter. From its fangs, the spider delivers a powerful neurotoxin that cause extreme pain and are capable of killing a person within 15 minutes. It's venom does not affect most mammals but has a very powerful effect on humans.

Poison Dart Frog


While running through the rain forests of Central or South America, do not pick up the Poison dart frog. The frog's skin contains a toxic chemical that sickens or kills any animal that touches or eats it. Two micrograms of this deadly toxin (enough to fit on the head of a pin) will easily kill a human being or other large mammal.

I hoped you liked this venomous animals compilation.

Stunning Nanotechnology Images

The 2007 Materials Research Society (MRS) Fall Meeting concluded in Boston on November 30. The images was taken from Science as Art competition that was held at MRS.



Nano-Explosions Color-enhanced scanning electron micrograph of an overflowed electrodeposited magnetic nanowire array (CoFeB), where the template has been subsequently completely etched. It’s a reminder that nanoscale research can have unpredicted consequences at a high level.


Dirty Dice Self-assembled 200 micron size nickel dice, imaged using scanning electron microscopy in the lower secondary electron (LEI) mode. The dice were colorized using Adobe Photoshop.


Bamboos for Vibration Control Ni-Mn-Ga melt-extracted fibers with an approximate diameter of 100 µm showing a bamboo-type structure

Interesting Natural Phenomenon -- The red tide

"Red tide is an estuarine or marine algal bloom [a relatively rapid increase in the population of (usually) phytoplankton algae in an aquatic system] and is caused by a species of dinoflagellates, often present in sufficient numbers (thousands or millions of cells per milliliter) to turn the water red or brown. Coastal water pollution produced by humans and systematic increase in sea water temperature appear to be causal factors in red tides. On the Pacific Coast of the U.S. there have been apparent increases in the occurrence of red tides since about 1991. These increases are correlated with a marine temperature rise of about one degree Celsius, and also with increased nutrient loading into ocean waters. Additionally, red tide can assume its dormant form if the water cools to a sufficient degree. When it does this it forms cysts which drop to the ocean floor and rebloom if the right conditions occur."(Read more)

things -- the phytoplankton algae.
frameworks -- the thousands or millions of phytoplankton cells that come together.c
lockworks -- water pollution and a decrease water temperature cause this event to happen. it can come and go whenever these situations are present.
