Amazing facts about animals

1. The heart of a shrimp is located in its head:

Some marvelous animals have physical peculiarities and secrets about animals that we don’t even know. If you read it, you will be surprised by how many mysterious creatures there are. Shrimp’s Heart Located in the Head.

Shrimp is considered to be seafood. Many of you love to eat shrimps like other seafood as lobster, prawns, crab, etc. Well, amazingly it’s true that shrimp’s heart is located on its head. The heart of shrimp is located on its thorax region just after the head but it seems as situated in its head because the head and the thorax are covered with a single exoskeleton only. This is because the shrimp's thorax can be mistaken as still part of the shrimp's head. Normally we see the shrimp divide only into two parts, the head, and the tail. It does not mean that shrimp's brain is located on its chest. It is located on the shrimp's true head, just after its eyes.

Having organs located in their head is much more advantageous and safer than having them located in the tail part. That’s because the head (cephalic portion) is covered with thick protective substances.

It’s much safer to protect their internal organ. Their heart located in its head has three pairs of heart entrances. Through these entrances, blood comes to the heart. The arteries extend for many directions.

2. A Snail can sleep for three years:

Snails need moisture to survive; so if the weather is not cooperating, they can 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. During this time, the snails will secrete mucus over their bodies to protect themselves from the dry, hot weather. As glamorous as it may sound, snails don’t always sleep for three years in their mucus. When the weather is just right, snails do tend to follow a pretty regular sleep schedule. Unlike humans, snails don’t abide by the rules of night and day. Generally, snails will sleep on and off in between periods of 13 to 15 hours. Afterward, they experience a sudden jolt of energy for the next 30 hours, where they get all their snail chores done!

t can be pretty tough to determine whether or not a snail is sleeping, considering they don’t show any obvious signs such as having their eyes closed or snoring. However, there are still a few simple ways that can help you tell whether or not a snail is sleeping:

  • The shell may hang away from their body slightly
  • Relaxed foot
  • Tentacles appear withdrawn a little

It may be easy to assume that the gastropod is dead, but don’t jump to conclusions when you see an immobile snail in the garden — it may just be taking a power nap.

3. It takes a sloth two weeks to digest its food:

It is believed that sloths have the slowest digestive rate of any mammal, but the true rate of food passage from ingestion to excretion is still debated. In 1978 Montgomery and Sunquist claimed the rate of digestion in the three-fingered sloth to be the slowest recorded for any herbivorous mammal, with 50 days being taken for the passage of 95% of 3mm glass beads. But it is highly unlikely that these beads would have passed through the sloths many stomachs in the same manner as their natural diet would. It is thought that the beads probably became lodged in the pre-pyloric stomach, lengthening the retention time.

4. An Ostrich's eye is bigger than its brain:

Ostrich is the largest bird in the world having the largest eyes in the whole animal kingdom that are even bigger than its brain. An ostrich's eyes are about 2 inches (5 centimeters) in diameter, i.e. almost of the size of a billiard ball. The ostrich needs large eyes to adapt to its terrestrial lifestyle. On sighting any danger, it doesn’t hide its head in the sand as is popularly believed. Thanks to the long neck and legs which make it stand up to the height of 9 ft, it enjoys an excellent view over the grassland and bush. Its large eyes with a high number of photoreceptor cells combined with the sheer size of the image from the lens help the ostrich to see phenomenal details of the predators even from great distances. So, if it sees something trying to sneak up on it then it will run away as fast as it can with its big, long powerful legs.

5. Frogs cannot vomit. If one has to, then it will vomit its entire stomach:


That potato salad sitting out in the heat too long is a recipe for food poisoning. Fortunately, you can get rid of the bad microbes you consume by vomiting. No so for frogs. If a frog eats something toxic, it can't eject its stomach contents. Instead, the frog throws up its entire stomach.

This is called full gastric eversion, and it's a little like dumping out your pockets. A tidy creature, the frog wipes the stomach hanging out of its mouth with its front feet to remove any stray bits. Then it packs the whole thing back into its body, where it will presumably stay until the next noxious tidbit is eaten.

People feel nausea before they throw up, probably, so they learn to avoid whatever made them sick. Of course, there's no way to know if a frog feels a little green before it turns its tummy inside out.

Frogs aren't the only animals that can't vomit. Others include horses, rabbits, and rats – one reason rat poison is so effective. And some animals share the frog's talent for throwing up the entire organ. When a shark can't stomach what it ate or feels threatened, full gastric eversion allows it to avoid poison and evade predators.

Some animals do frogs one better. Sea cucumbers, chubby wormlike creatures related to sea stars, can poop out their intestines as self-defense to tangle up and frighten predators. They can even break off their guts to escape, a kind of self-amputation called autotomy. Intestines regrow quickly, and the sea cukes seem none the worse for wear.
