Well, one species of animal is actually immortal! Immortality means 'eternal life', which is the ability to live forever! The
The 'immortal' jellyfish, Turritopsis dohrnii
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
Regenerating flatworms
This apparently limitless regeneration also applies to aging and damaged tissue, allowing the worms to cheat death indefinitely, according to a study at the University of Nottingham.
Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life.
The Scoop. The honey badger has been called the world's most fearless animal because it doesn't hesitate to attack animals much larger than itself- even lions and crocodiles! Honey badgers are found in arid grasslands and savannahs and even rainforests.
An elephant, of course, especially an adult elephant. Elephants are the kings (and queens since they're matriarchal) of brute strength among land animals.
Too Weak to Support Its Own Body Weight: The Jellyfish
Almost every living creature on the planet has at least the strength to support its own body and move around. One exception to this is the jellyfish that is one of the weakest animals.
CHIMPANZEES. RECKONED to be the most-intelligent animals on the planet, chimps can manipulate the environment and their surroundings to help themselves and their community. They can work out how to use things as tools to get things done faster, and they have outsmarted people many a time.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood.
Did anyone know that some animals have blue blood, especially when it is exposed to oxygen? Can you guess what animals might have blue blood? Lobsters, crabs, pillbugs, shrimp, octopus, crayfish, scallops, barnacles, snails, small worms (except earthworms), clams, squid, slugs, mussels, horseshoe crabs, most spiders.
They react differently when external stimuli are applied while sleeping and while awake. But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
It's a common saying that elephants never forget. But the more we learn about elephants, the more it appears that their impressive memory is only one aspect of an incredible intelligence that makes them some of the most social, creative, and benevolent creatures on Earth.
Snails have more teeth than any animal.
This is TRUE. A snail's mouth is no larger than the head of a pin, but can have over 25,000 teeth (but these aren't like regular teeth, they are on its tongue).
African bush elephant (Loxodonta africana)
Adult African bush elephants can weigh 18,000 pounds and stand at a shoulder height of 13 feet. They are considered the strongest land animal and strongest mammals in the world by pure strength. An African bush elephant can lift a 250 kg object with just its trunk.
They conclude that while one on one, a tiger would certainly best a lion, in the wild the lion pride could hold their own against the solitary tiger.
Gorilla. Gorillas are the largest apes (not monkeys!) and the strongest primate, known for their impressive strength. These powerful animals weigh up to 200 kg, and can lift almost 2,000 kg – 10 times their body weight.
Which animal can you beat in a fight? The weakest animal you could beat in a fight is a rat or cat (around 70%) while the strongest animal you could beat is a grizzly bear, lion, elephant, or gorilla (around 3%). The other animals include goose, dog, eagle, chimpanzee, cobra, kangaroo, wolf, and crocodile.
Butterflies are not even able to defend themselves. The worst they can do is make one of their predators feel ill after it eats a butterfly. Conservationists have stressed that healthy moth and butterfly populations are essential to most ecosystems.
While mammals and birds possess the prerequisite neural architecture for phenomenal consciousness, it is concluded that fish lack these essential characteristics and hence do not feel pain.
The results show that the elephant wears the crown in the animal kingdom – but only slightly. Elephants had a win rate of 74%, just fractions of a percent ahead of their single-horned cousins – the rhinoceros – in second place, also on 74%.
