Nuzil Blog Community - Many Indonesians believe that when a house gecko, locally known as tokek, bites you, it won't let go until thunder crashes. This belief stems from the fact that a gecko's jaw is very powerful and it can be quite difficult to pull the lizard off you. But, of course, it doesn't really take a thunder to make the gecko let go, just a drop of vinegar om its nose. Can you tell if the following beliefs about certain animals are fact or fiction ?
Fact or fiction ? The dinosaur was the biggest animal that ever lived.
Amazingly, the largest animal that has lived in the blue whale. It's even large than the largest dinosaur ! The biggest blue whale ever recorded was around 33 meters and weighed about 200 tons. These sea mammals breathe using a blowhole on top of their head. The blowhole is large enough for a baby to crawl through. When a blue whale exhales, the blow can reach up to 9 meters. A blue whale has an incredibly big mouth which can accommodate 400 people. This big mouth can swallow a volume of water larger than their body.
Fact or fiction ? Ladybugs are not bugs.
Yep, ladybugs are not bugs or pests (Indon.:hama), nor are they all female. Ladybugs are somewhat perplexing insects. They were at first thought to be eating crops just like other insects. But actually they eat the bugs that destroy crops. Now farmers breed them because they exterminate bugs without the farmers having to use pesticides. Another interesting fact about ladybugs is the way they protect themselves. To warn off enemies or predators, a ladybug will play dead. It will pull its legs up in "turtle-style" and release a small amount of blood, which is called reflex blood, from its legs The bad smell from the fake blood and dead-like look usually deter predators from munching on this small ladybug snack. After the threat of danger has passed, the ladybug will resume its normal activities.
Fact or fiction ? Crocodiles don't have tear ducts.
Ever heard of the expression "to cry crocodile tears"? It's an expression used for depicting fake sadness because it was believed that this reptile didn't have tear ducts. However, scientists have found out otherwise. Crocodiles do have tear ducts, which produce tears when the animals eyes get too dry. According to another myth, crocodiles even weep while they are eating humans. This is not completely untrue. Crocodiles really weep while eating, but for emotional reasons. As they eat, air gets inside their nose, up to tear ducts and mixes with the tears. This air-tears mix gets pushed out through the eyes, making it look like crocodiles cry whenever they're feasting.
Fact or fiction ? The ostrich buries its head in the sand when in danger.
The ostrich is one of the large flightless birds. Cartoons often depict them burying head in the sand. People also use the expression "hiding your head in the sand like an ostrich" to say you are ignoring a problem instead of trying to solve it. But you will never actually see an ostrich do that. This myth is likely to come from the fact that when an ostrich feeds, it sometimes lays its head flat on the ground to swallow sand and pebbles, which help to grind food in its throat. This creates an illusion of the animal burying its head. Also when a hen is sitting on its eggs, it may lay still with its head flat on the ground, the color of the head blnding in the sand.
Fact or fiction ? Meerkarts are altruistic animals.
Altruistic means caring about the needs and happiness of other people more than you own. Meerkats are small mammals native to several parts of Africa. Well-known for their extremely social behavior, meerkats live in a tight-knit colony of 20-30 individuals led by an alpha (dominant) couple. When the alpha couple goes out searching for food, one or more meerkarts will stand guard to keep an eye out for predators for up to an hour at a time. Then other guards will have a turn. Then other guards will have a turn. They also feed the pups together. Female meerkats babysit and wt nurse their little colony members. The most unusual thing about meerkats is how they teach the pups to hunt for food. For example, the pups are shown how to tackle a scorpion --their favorite food. The adult removes the stinger to show the pups how to learn to kill a scorpion safely.
