Which animal never dies
jellyfish
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.
Can ants sleep
They sure do. And just like us, the amount of sleep they need varies. Queen fire ants fall into relatively long, deep sleeps and kip for an average of nine hours every day. The busy worker ants, on the other hand, get their rest by taking hundreds of short power naps.
Do any animals not need sleep
As weird as it sounds, but it's true, newborn dolphins don't sleep for a month. Scientists found that even the mother stays awake during this time. Dolphins can stay alert with at least one eye open at all times. They can even swim while sleeping.
What animals don’t feel pain
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.
Which animal can sleep than 3 years
Snails
Why Do Snails Sleep So Long Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years.

Which animal can sleep for 3 years
Snails
Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as 'summer sleep'), helping to escape warm climates.
Which animal has no blood
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood.
What is the saddest animal death
1 Fight The Sadness, Artax
The saddest animal death in film history is during the 1984 film The NeverEnding Story, based on Michael Ende's 1979 eponymous novel. The NeverEnding Story only covers the first half of Ende's novel, with the sequel based on the second half.
Do plants go to sleep
Although plants do not sleep in the same way that humans do, they do have more and less active times and they have circadian rhythms—internal clocks that tell them when it is night and when it is day. And like many people, plants are less active at night. When the Sun comes up, however, they awake to the day.
Do ants have hearts
Ants do not breathe like we do. They take in oxygen through tiny holes all over the body called spiracles. They emit carbon dioxide through these same holes. The heart is a long tube that pumps colorless blood from the head throughout the body and then back up to the head again.
Do sharks fall asleep
Some sharks such as the nurse shark have spiracles that force water across their gills allowing for stationary rest. Sharks do not sleep like humans do, but instead have active and restful periods.
Do bugs feel pain
Scholars have long recognised that the survival value of pain means many animals experience it, supposedly with the exception of insects. But we surveyed more than 300 scientific studies and found evidence that at least some insects feel pain.
Can fish feel pain
Neurobiologists have long recognized that fish have nervous systems that comprehend and respond to pain. Fish, like “higher vertebrates,” have neurotransmitters such as endorphins that relieve suffering—the only reason for their nervous systems to produce these painkillers is to alleviate pain.
What animal sleeps 90% of its life
Koalas
Koalas. Hats off to the (somewhat disputed) king of sleep: the Koala bear. They've been reported to sleep up to 22 hours a day in captivity, over 90% of their lives. In the Australian wild, that figure may be closer to 14.5 hours of sleep daily, boosted by 5 additional hours of rest and inactivity.
Which animal has longest memory
The new research shows that dolphins have the longest memory yet known in any species other than people.
Does fish feel pain
“Fish do feel pain. It's likely different from what humans feel, but it is still a kind of pain.” At the anatomical level, fish have neurons known as nociceptors, which detect potential harm, such as high temperatures, intense pressure, and caustic chemicals.
Which animal has no heart
There are also numerous animals with no hearts at all, including starfish, sea cucumbers and coral. Jellyfish can grow quite large, but they also don't have hearts. Or brains.
Which organ has no blood
the cornea
The only part of the body that has no blood supply is the cornea in the eye. It takes in oxygen directly from the air.
What animals can’t cry
Baby animals that are separated from their mothers sound a cry, but humans are the only ones who shed tears. (Stone/ Getty) Pet owners often claim their dogs cry. Darwin thought monkeys and elephants wept. But modern scientists believe the only animal to really break down in tears is us.
What animal dies from anxiety
A giraffe who was put under too much stress during a planned move has died from anxiety.
