Blue-ringed octopus - This species is known for its beautiful colored rings and can be found in Australia and Japan.

Its toxins are so strong that they can kill up to 26 adults in a matter of minutes. The octopus can produce two kinds of venom: one to kill victims and another to weaken them.

Pitohui - This small bird is native to New Guinea and its feathers contain venom that is capable of killing multiple people.

It is so far the only venomous bird to be discovered. Its toxins cause paralysis and can be fatal, as they also stop the heart.

Platypus - This semi-aquatic mammal is native to Australia, including Tasmania. Only male platypus carry venom, which is found in their ankle spurs.

Platypus are not poisonous enough to kill humans, but they can kill other animals, including dogs. If a human was stung by a platypus they would feel an intense and unbearable pain.

Poison dart frog - This species of frog is mainly found in South and Central America. Its poison can be fatal and one dose could kill up to 20 adult humans.

The smallest touch can infect people with its venom, so the best thing is to appreciate this animal's beautiful coloring from afar.

Deathstalker - This animal can be found in North Africa and the Middle East. It carries a poison that can kill humans.

It is considered the most dangerous type of scorpion and one sting can kill a person or leave them unconscious. Its sting causes extremely intense pain.

Black widow - These spiders are found in North American. The female has a red mark in the middle of its abdomen, and a lifespan four times that of the male.

A black widow bite is extremely painful and can be fatal.

Boomslang - This snake, native to Africa, rarely attacks humans but its venom can cause great pain.

Sometimes the victim's body goes blue due to internal hemorrhaging caused by the venom. This can lead to a slow and painful death.

Chimpanzees have great short-term visual memories. In studies conducted at Kyoto University in Japan, young chimps memorized and recalled number positions on a screen almost instantly. An adult human would struggle to do this.

The saying “an elephant never forgets” is actually backed by science. Elephants can remember the location of water sources in vast areas they haven’t visited for years. Plus, they can recognize other elephants as well as humans decades later!

Matriarch elephants hold spatial and social knowledge for over sixty or more years, allowing them to guide herds. When a matriarch dies, the herd loses this crucial memory, which can have an impact on their survival.

The African bush elephant is the largest and strongest land animal on Earth. Adult males can reach weights of 13,000 lbs (5,900 kg) and stand up to 13 ft (4 m) tall at the shoulder.

These are nature’s titans, with the ability to lift more than 13,200 lbs (6,000 kg). The trunk alone can carry 440 lbs (200 kg) of weight, and contains over 40,000 muscles.

Dolphins possess the longest social memory of any non-human species. Bottlenose dolphins, for instance, can recognize the signature whistles of former companions even after more than 20 years apart!

Living in fluid social groups, this long-term recognition is very useful. This proves that their memory goes far beyond just familiarity.

Dolphins, similar to bats and a few other animals, have the amazing ability of echolocation to help them navigate the ocean. The dolphin emits a soundwave that then bounces off any objects in front of it, giving the dolphin a mental map of what lies ahead.

Guiana dolphins, found off the eastern coasts of South and Central America, take it a step further. Not only are they equipped with echolocation, but they are also blessed with the skill of electroreception, which allows them to sense the faint bioelectric signatures that are produced by nerves and muscles.

Octopuses are highly intelligent animals. They can remember solutions to problems, recognize human faces, and track which foraging routes have been successful. Interestingly, unlike humans and other animals, much of this memory is processed in their arms rather than in a centralized brain.

Octopuses also recall negative experiences with humans. They will remember if a keeper treats them poorly and respond appropriately, even months after the fact.

While octopuses don't possess circular light polarization like the mantis shrimp, they do make frequent use of linear light polarization. This also allows them to manipulate the amount of light absorbed by their eyes, which they can optimize for any situation.

Honeybees can simultaneously remember the location, quality, and even the time some flowers produce nectar. They can also recall the route back to the hive. Their long-term memory for landmarks helps them locate reliable food sources weeks later

Their famous waggle dance communicates this spatial information to other bees so that they can navigate accurately.

The way bees behave is pretty impressive, considering they have about one million neurons, which is a pretty low number when compared to humans, who have around 86 billion.

In addittion:-

Crows can remember human faces very well and actually hold grudges for years. Researchers at the University of Washington found that crows would scold and mob people wearing the same masks used years earlier during capture. Plus, they went as far as passing this behavior onto their young, who, despite not experiencing the event, reacted in the same way.

Passing this kind of social memory to the next generation is very rare in animals. Scientists are still trying to fully understand how this happens in birds such as crows.
