The animal with the sharpest tongue, in terms of abrasive power for grooming and stripping flesh, is the tiger, thanks to its tongue covered in backward-facing, keratin spines (papillae) that act like sandpaper, capable of licking fur off or drawing blood. Another contender for "sharp" is the lamprey, which uses a rasping, piston-like tongue with keratin hooks to burrow into prey for blood.
This is because tiger's tongue is covered with small, sharp, backward-facing spines called papillae, giving it an abrasive texture. The roughness also helps with grooming and even cleaning wounds (carefully).
Tiger. Tigers have sharp, rough tongues with sharp spikes all over that help them lick meat off bodies and bones. They are also powerful in gripping, making sure the prey does not escape.
Chameleons. Chameleons are relatively slow creatures, but their 20-inch-long (50 cm) tongues are fast enough to catch speedy insects, such as locusts, mantids and grasshoppers. The tip of the chameleon's tongue is a ball of muscle, and once it hits prey, that ball transforms into a suction cup.
The northern leopard frog Rana pipiens has a measured tongue tensile stiffness of 4.2 kPa ex vivo, 70 times softer than the human tongue.
Yes - a lion's tongue can actually tear your skin, but not in the way you might imagine. Unlike household cats with their small, harmless tongues, lions possess a specialized tongue covered in tiny but incredibly sharp spine-like structures called papillae.
A crocodile cannot stick out its tongue. It's one of the most unique features in the animal kingdom. Unlike most animals, a crocodile's tongue is held in place by a membrane that fastens it to the bottom of its mouth.
The eagle eye is among the sharpest and most fearsome in the animal kingdom. Eagle eyesight is estimated to be around four to eight times stronger than that of the average human.
A tiger's tongue is covered in papillae — tiny, backward-facing, hook-like structures made of keratin (the same stuff as claws and hair). These structures give the tongue a rough, sandpaper-like texture.
The tongue of the common hippopotamus had each of the following lingual papilla: filiform, fungiform, conical, foliate, and large conical papillae.
Blobfish. The blobfish, often cited as the world's ugliest animal, resides in deep waters off Australia and Tasmania.
A tiger's tongue isn't just rough — it's a deadly tool.
Big cats such as lions, tigers and cheetahs have some of the sharpest canine teeth in the animal kingdom. These long, dagger-like weapons are used to stab – biting down deeply into the throats of prey to bring them down.
Thousands of tiny spiny processes called papillae, make a lions tongue extremely rough. So rough that it's like being licked with 180 grade sandpaper. Enough times in one spot and you start to get abrasions and bleed. Their tongues are used in social grooming (what he's doing to me), self care, drinking and eating.
Just like an elephant's trunk or a monkey's tail – giraffe have a prehensile tongue! Basically it means they have fine muscular control allowing them to grasp and hold things. A giraffe's tongue is also the strongest of any animal, and it can be an impressive 18 inches long!
The heaviest tongue of any animal is that of the blue whale (Balaenoptera musculus), which typically weighs 4 tonnes (8,818 lb) - similar to the total body weight of an adult elephant! The area of the tongue is large enough to support 50 people standing on it!
The saltwater crocodile (Crocodylus porosus) has the strongest physically measured bite force at 16,414 N. This powerful bite came from one 3,689-pound (1,763.3-kg) individual as part of a 2012 study that measured the bite force of 83 adult specimens from all 23 recognized crocodilian species.
Researchers filmed tongue strikes of chameleons attacking a suspended cricket, at 3000 frames per second. They found that the animals' tongues are capable of impressive acceleration, doing 0 kilometers to 100 kilometers per hour in one-hundredth of a second, twice as fast as the fastest car.
1. Chimpanzees. Chimpanzees and bonobos are fiercely intelligent creatures with complex social hierarchies. That's not really surprising, considering they share 98.7 per cent of their DNA with humans.
Leeches have 32 brains. Humans love to think we're the brainiest species around, but leeches have an impressive 32 brains (making them absolute shoo-ins if Mensa ever expands their ranks to include nonhuman animals).
1. Mosquito (780,000 deaths per year) The tiny mosquito is the most dangerous animal in the world as well as the most dangerous insect, claiming 780,000 lives annually. These relentless pests spread destructive diseases, including malaria, dengue fever, Zika virus, and West Nile virus, primarily through their bites.
Other animals naturally have no tongues, such as sea stars, sea urchins and other echinoderms, as well as crustaceans, says Chris Mah via email. Mah is a marine invertebrate zoologist at the Smithsonian National Museum of Natural History and has discovered numerous species of sea stars.
Packing more than 3,000 pounds of pressure per square inch, these ancient predators can crush bone and lock onto their prey with jaw strength few animals on Earth can rival.
Crocodilians have a fleshy tongue that is attached along its length between the lower jaws. Lingual glands in the posterior part of the tongue are actually salt glands, which excrete excess salt when the animals are in highly saline environments.
