What are the fun facts of tardigrade?

Tardigrade is a microscopic animal found everywhere on Earth – from the deep sea in the mud volcanoes. There are around 1300 species of tardigrades. We are also called water bears or moss piglets.

It has eight limbs with four to eight claws on each. Its body is covered in a tough cuticle, similar to the exoskeletons. It is known for being the most resilient animal, because it can survive extreme conditions such as exposure to extreme temperatures, extreme pressures, radiation and starvation. It can go up to 30 years without food and water.

In extreme dry conditions, it gets into a death-like state called cryptobiosis. It squeezes all the water out of its body, retract its heads and limbs and curl up into a little ball. When conditions improve, it unfurls itself and goes about its business. It sucks the juices from algae, lichens and moss using its tube-shaped mouth.

What are the fun facts of hedgehog?

Hedgehog is a spiny mammal that belongs to the family Erinaceidae, found in Europe, Asia and Africa. It has an elongated snout and body covered with 5000 to 6500 non-poisonous quills. It replaces the old quills with new ones each yea.

If attached it curls into a prickly and unapestising ball that deters most predators. It feeds on insects, worms, centipedes, snails, mice, frogs and snakes. It hibernates in cold climates.

The body of adult hedgehogs ranges from 14 to 30 centimetres long, and their tail can add one to six centimetres. When they are born (there can be up to seven in a litter) their spines are soft and short. But soon after birth, their spines harden, becoming stiffer, sharper and longer. Babies stay in the nest until they”re about three weeks old. By that time, their eyes are open, their spines are effective and they can safely follow their mother outside the nest as she looks for food.

Top on the hedgehog”s menu are insects, followed by small mice, snails, lizards, frogs, eggs and even snakes. Mostly nocturnal creatures, they head out at night in search of food – but they are sometimes active during the day, too, particularly after it rains.

Do turtles talk?

Yes, they do, says research. Since turtles don't have vocal cords, it was thought that they did not communicate through sounds. However, scientists have found that turtles communicate at such low frequency that sounds like "clicks, clucks and hoots" can be heard only through a hydrophone. What's surprising is that they talk when they are still inside their eggs just before hatching.

One of the most common sounds which a turtle may produce is the hissing sound. Turtles hiss by quickly expelling air from their lungs. They do this by tucking their heads into their shells.

A turtle in a new environment will hiss a lot as it is not used to its environment. Once the turtle gets used to its environment, you can expect it to hiss less. Snappers) hiss when approached.

They do this because they are stressed and feel threatened. Hissing coupled with heavy breathing produces a menacing sound. A threatened snapping turtle will attack when approached or provoked. Their bites are very powerful and are capable of crushing human bones.

When a turtle hisses, it’s best to leave it alone.

Which is the oldest living land animal?

Heard of Jonathan, the Seychelles giant tortoise? Aged 188, he is the oldest living land animal in the world. Said to have hatched in 1832, he lives on the island of St. Helena, a British Overseas Territory in the South Atlantic Ocean.

His age is estimated because he was 'fully mature' when brought to Saint Helena in 1882. 'Fully mature' means at least 50 years old, giving him a hatching date no later than 1832. A photograph featuring Jonathan originally thought to date from 1902 actually dates from 1886, showing Jonathan four years after his arrival on Saint Helena. Measurements taken from the photograph show that he was definitely fully mature in 1886.

The all-time verified record holder for the world's oldest tortoise, according to Guinness World Records, is Tu'i Malila, which died in Tonga in 1966 at the age of 189. Adwaita, an Aldabra giant tortoise that died in 2006 in the Alipore Zoological Gardens of Kolkata, India, is believed to have lived to the age of 255 years, but this has not been confirmed.

As of December 2015, Jonathan was reported to be "alive and well [...] He's blind from cataracts, has lost his sense of smell, and so cannot detect food (his fellow giants mug me and can detect the tiniest morsel dropped on the ground), but he has retained excellent hearing." In January 2016, the BBC reported that Jonathan was given a new diet intended to keep him healthy and extend his life. Due to his old age, Jonathan spends his days doing almost everything with his mate, including eating, sleeping, and mating.

What do you call the flap of skin over a turkey’s beak?

The snood is similar to a wattle, and may be called a wattle when all of a turkey's face, head, and neck markings are described together, but it is a distinct feature. The base of the snood is just above the bill, and the total length can vary from just 1-2 inches to 5-6 inches or longer depending on the bird's gender, health, and mood. A short snood may stand upright and be pointed like a small horn, while a longer snood will dangle down the bird's bill and may flop on one side or the other.

A snood is a fleshy protuberance above a male turkey's bill that can, in some cases, hang down and cover the bill. It can vary dramatically in size, shape, and color. Snoods function in sexual selection: Female turkeys choose who to mate with based on a variety of factors including snood size.

Because the snood is fleshy and blood-filled, it can change length quickly. A short, compact snood may indicate an agitated bird, and turkey hunters have noted the snood shortening and withdrawing when a bird feels trapped or threatened. This may be a defensive response, since a long, dangling snood can be a hazard in a fight: if the snood is injured, the bird may bleed profusely, and the snood could easily become infected through an open wound. Because turkeys can be aggressive, farmers who raise turkeys may have their birds de-snooded as chicks, removing the protuberance and lessening the risk of injury or infection.
