Taste sensations Other animals naturally have no tongues, such as sea stars, sea urchins and other echinoderms, as well as crustaceans, says Chris Mah via email.
Icthyophis is a limbless amphibian showing parental care. It has no tongue.
Fish tongues however do not resemble the muscular tongues of humans. The tongue of a fish is formed from a fold in the floor of the mouth. In some species of bony fishes the tongue has teeth which help to hold prey items. The name of one genus of argentinid fish, Glossanodon, literally means 'tongue teeth'.
Lemurs have a second tongue—called the “sublingua”—that is used to remove debris from the tooth comb. The sublingua is smaller than the primary tongue, sits below it and lacks taste buds.
Not all the animals, of course. Worms like platelminthes or cestods don't have it. Insects have the taste sense but haven't tongue. Terrestrial vertebrates have tongues except loricati (crocodiles' family).
A crocodile can't stick its tongue out.
In sharks, the tongue is a small, flattened structure that is attached to the floor of the mouth. It is made of cartilage, just like the rest of the shark's skeleton, and it is covered with tiny, tooth-like structures known as papillae. These papillae help the shark to grip and manipulate food in its mouth.
Crocodiles have a membrane that holds their tongue in place on the roof of their mouth so it doesn't move. This makes it impossible for them to stick it outside of their narrow mouths. That can be handy for the reptile when snapping its jaws shut rapidly.
All species have different breeds of bacteria that are able to survive in their saliva, so it would be extremely hard to answer the question of which animal has the cleanest tongue. There's a myth that dogs have the cleanest mouth, even cleaner than humans, supported by no scientific evidence.
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
The cerebral cortex and limbic system are absent in fish. Cerebral cortex, which is what permits other animals to cry.
Fish pee the same just as you and me. Fish kidneys, usually tucked above their swim bladder, are responsible for filtering out all the bad things in their blood and peeing them out into the water. In fish, some products are actually pushed out through a similar fashion in the gills.
The team found that hippo tongues have features similar to a few types of animals: odd-toed ungulates (such as donkeys, which digest plant cellulose in the intestines, not the stomach), ruminants (such as cattle, which have four-chambered stomachs) and omnivorous, non-ruminant mammals (such as pigs, which have simple ...
Based on similarities they found between dinosaur and crocodilian hyoid bones, the researchers found that dinosaurs' tongues were probably like those of alligators and crocodiles—firmly attached to the floor of their mouths.
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!
Like sea urchins, hydras also respond to light even though they lack eyes. When scientists sequenced the genome of Hydra magnipapillata, they found plenty of opsin genes. Recently, scientists confirmed that hydras have opsins in their tentacles, specifically in their stinging cells, known as cnidocytes.
Giraffe (Giraffa camelopardalis), as African megaherbivores, are the tallest mammals, with both long necks and legs. Its neck is the longest on any extant animal at around 2–3 meters in the largest males [1].
Nick Stoeberl from Salinas, California, USA currently holds the record for the world's longest tongue (male), measuring in at 10.1 cm (3.97). The world's longest tongue (female) belongs to Chanel Tapper from Los Angeles, California, USA, and measures 9.75 cm (3.8 in).
First, most birds have pretty prosaic tongues. They look somewhat similar to ours but can have some interesting extra features. As shown in Figure 1, the tips can be fringed or split and the root of the tongue may have backward-facing barbs.
Most reptiles have two atria and one ventricle. The only exceptions are the 23 living species of crocodilians (alligators, caimans, crocodiles and gharials) who, like birds and mammals, have four-chambered hearts with two atria and two ventricles (Jones, 1996; Jensen et al., 2014).
Especially during mating season (May-August). Be very careful. It is highly recommended that all menstruating women wear a diaper in addition to a full wetsuit too help cover the scent of their menstruations. Like bears, gators can smell the menstruation, which will put your entire party at risk.
So, do sharks poop? They sure do! Every living animal that consumes food has to have a way of getting rid of waste. Sharks are no different.
Sharks urinate continuously
In fact, shark's don't pee as we know it at all. Their urine is actually absorbed by their flesh, where the urea is used to keep their scale-like dermal denticles nice and moist. The rest is simply expelled back into the water through their 'skin'.
Actually, no, spiders do not have a tongue in the same sense we do. Their mouthparts- chelicerae (fangs), endites or maxillae (modified bases or coxi of palpi), palpi (feelers) and labium (a sort of "tongue")-act to manipulate prey and form the mouth.
