Top5: You better steer clear of these venomous (or poisonous?) animals
When we start talking about animals that can easily kill or at least terribly hurt humans, we have to start with a clarification: There’s a difference between venomous and poisonous creatures. The difference lies in the delivery of the toxic material that harms a human being. Let’s say, a king cobra bites you, it delivers the poison by performing an action. That’s called venomous. If you, on the other hand, happen to eat incompetently prepared toxic puffer fish (or Fugu), it’s called poisonous. The fish does not take action but scores a strike anyway. Fugu is considered to be a delicacy in Japan, by the way. When its organs, which are covered by neurotoxins are hurt, the meal could easily become the last one for the brave eater.
So how do we compile this list of the Top5 of venomous (or poisonous) animals? We take the deadliness of the candidates into account. And here are the winners of the competition, remarkably enough most of them live in the oceans:
But let’s stay out of the water first. The poison dart frogs are a group of frogs (Dendrobatidae) in various colors from blue to red or black. The most deadly species is called the golden dart frog. It caries enough venom to kill 10 grown men. The frogs were given the name by the indigenous people of Colombia who used the strong toxic to tip their blowgun darts for hunting.
You have to look twice to not step upon the second member of our list. The stonefish got its name from its ability to camouflage itself by donning stone like colors. But what is so dangerous about this fish? Along the stonefish’s back a row of 13 venomous spikes is protruding from its spine. It does not really attack its victims, but squeezed or pressured the spines release their venom. The result is terrible pain, muscle weakness, shock and – if untreated – death.
The next sea creature in our list you better not pick up as well. The marbled cone snail has a sting to protect itself from enemies. But also to attack , if a careless collector comes up with the slightly stupid idea to grab the marble housing. As there is no antidote available, touching the snail most commonly is followed up by an initial sharp pain, paralysis and may result in death within 2 to 6 hours.
Number four: The Blue-ringed octopus is as deadly as any other of the competitors in the list. And it is malicious because it bites and the bite is said to be painless. If bitten the clinical effects depend on how much of the venom was transferred into the wound. Usually the symptoms set in fast. Within minutes, the victims feel numbness, muscular weakness and difficulty breathing and swallowing. Death is possible. Experiments with the venom concluded that a single adult octopus is able to fatally paralyze 10 adult humans.
We started the list with a blue species and we are going to finish it the same way. The box jellyfish (or sea wasp) got it’s name from the shape of their bell. The jellyfish’s toxic is delivered through it’s up to 3 m (10ft) long tentacles to attack the victim’s heart, nervous system, and skin cells. Because of its painfulness, human victims may go into shock or die by heart failure. It’s possible to survive attacks, but survivors experience long-lasting pain and often have scars where the tentacles made contact.
Stay save out there.

5 smallest animals
Lists are somehow en vogue so we’ve put some together for you – like the 5 smallest animals in the world (to be completely honest, we should say “the five smallest animals – that we found pictures for”).
Hippocampus denise – the smallest seahorse
The Denise’s pygmy seahorse grows only 1.5 centimeters long and are named after the underwater-photographer Denise Nielsen-Tackett.
Brookesia micra – the smallest reptile
This chameleon – that does not have a non-scientific name (yet) – is with a maximum length of 29 millimeters the smallest known reptile. It lives only in one spot on our planet: in the North of Madagascar.
Leptotyphlops or Tetracheilostoma carlae – the smallest snake
As thin as a spaghetti noodle, you better don’t chew on it or dip it in tomato sauce… with a maximum length of 104 millimeters it won’t satisfy your hunger anyway. If you are curious about the name: It’s discoverer Blair Hedges named it after his wife Carla Ann.
Mellisuga helenae – the smallest bird
The bee hummingbird flies around mainly in Cuba – and can easily been overlooked as it is only about 6 centimeters long and quite fast: during one day it visits about 1,500 flowers.
Paedophryne amauensis – the smallest frog
The smallest vertebrate – the frog Paedophryne amauensis – was found in Papua New Guinea, where it prefers to live in the leaf litter of the ground of tropical forests.
Among the cutest smallest animals is the Pygmy Marmoset.
