Updated on October 14, 2014

Top 10 Deadliest Venomous Animals

These are the infamous “Top 10 Deadliest Venomous Animals”. Several researches have been conducted, yet the antidotes for these creatures’ venoms are either not yet available or already available but have yet to prove its effectiveness.

Number 10: Puffer Fish

Considered as the 2nd most venomous vertebrate on this planet, this round shaped unfriendly looking fish is also called in various names: blowfish, balloon fish, globefish, bubble fish, and sea squab. The skin and certain internal organs, such as the liver is extremely toxic that when eaten will cause faintness, vomiting, numbing of the lips and tongue, fast heart rate, difficulty in breathing, and muscle paralysis. Fatality is so fast; victim may die within four to twenty-four hours. Diaphragm muscles are paralyzed leading to suffocation. Most deaths are from Japan and Korea since this is their delicacy. Since the fish poison may cause on the spot death, only licensed chefs are permitted to prepare it.

Number 9: Poison Dart Frog

Attractive as they seem because of their brightly-colored skin, don’t even think of touching them. Commonly found in South and Central America is considered as the most poisonous frog. Also called poison arrow frog, the lipophilic alkaloid toxin that they secrete through their skin can kill ten to twenty men. Two microgram of this toxin is more than enough to kill one human adult.

Number 8: Inland Taipan

Tagged as the most venomous snake in the world is this Australian native reptile. The Inland Taipan has earned its place in the Top 10 Deadliest Venomous Animal. A single bite contains enough toxins that can kill one hundred human adults. With extremely neurotic venom, death can come within forty-five minutes after a single bite. The venom is at least two hundred to four hundred more toxic than the toxin of a king cobra. Lucky for us it possess a timid personality, would rather escape than initiate contact with humans.

Number 7: Brazilian Wandering Spider

Considered as the most venomous spider and was responsible for most spider-related human deaths. Its neurotoxin causes difficulty in breathing and absence of muscle control which results in paralysis and eventually asphyxiation. Death can happen within two to twelve hours after contact. The wandering nature is considered perilous to humans since it likes to wander in a highly populated place.

Number 6: Stonefish

Crowned as the World’s Most Venomous Fish, this hideous-looking sea creature hides its toxins in its spines. Severe pain will be felt by anyone who was stung by its spines. So painful that the victim would want the affected part removed or amputated. It is accompanied with paralysis, possible shock and tissue death.

Number 5: Death Stalker Scorpion

Usually found in the scrub land and desert of North Africa and Middle East is the most venomous scorpion in the world. These extremely treacherous species with a venom that is a powerful mixture of neurotoxins which causes unbearable and intense pain, then fever, followed by paralysis, coma, convulsions, and death.

Number 4: Blue-Ringed Octopus

With no anti-venom yet available, this is a definite candidate for the Top 10 Deadliest Venomous Animal. Once stung by this small marine creature, a person will suffer numbing, motor paralysis and respiratory arrest within few minutes of contact. Cardiac arrest will follow due to lack of oxygen. The venom of one blue-ringed octopus can kill twenty-six adult humans.

Number 3: Marbled Cone Snail

Often found in warm salt waters, they may seem harmless but beware, a drop of their venom can kill more than twenty adult humans. Effects of the sting are numbing, inflammation, stinging, and extreme pain. With no antidote available yet, recorded severe cases showed muscle paralysis, changes in vision, and cessation of breathing.

Number 2: Black Mamba

With a mortality rate of close to 100%, the highest amongst venomous snakes, a Black Mamba bite can kill a human adult within ten minutes. Respiratory, neurological, and cardiovascular symptoms are evident within the first fifteen minutes after the bite. Dizziness, difficulty of breathing, convulsions, shock, loss of consciousness, excessive salivation, erratic heart beat, fever, severe abdominal pain and cardiac arrest. Black Mamba blows several strikes when threatened with bites landing to either the face or the body. Permanent paralysis is most likely to happen if treatment is delayed. Commonly found in the Africa, this snake can travel with a speed of up to twelve miles per hour.

Number 1: Box JellyFish

Found in the waters surrounding Australia and Asia is the gold prize winner of the Top 10 Deadliest Venomous Animal. With the most number of recorder deaths, its toxin attacks the skin cells, nervous system, and the heart. Taking an extremely painful sting, a victim usually goes into shock unable to swim and reach the shore they either drown or die due to heart failure. It is advised to wear panty hose while swimming to prevent the jellyfish from harming the legs.

      Thanks for the interesting hub and great photos. I am most familiar with the Brazilian Wandering Spider also known as the Banana Spider and 'interviewed' him/her/it. See my hub: "Interview with Banana Spider."
