No, it's a platypus! One of the most unique creatures on the planet, it is an egg-laying mammal with venom and no teeth.
Blue whales are the largest animals alive today and they have no teeth to eat food! Instead blue whales are filter feeders. There are a total of 15 types of whales that eat this way. These species are known as Baleen whales, because they have baleen plates instead of teeth.
Now we come to those that have no teeth or have only small and very weak teeth. This group includes the Anteaters, Sloths and Armadillos of America. The scientific name for these three kinds of animal is Edentata. This is from a Latin word and yes, you've guessed it, it means 'without teeth' or toothless.
Summary: Whereas human and many animals use teeth to crush or grind food as an initial part of the digestive process, some species such as birds that lack teeth grind food inside the gizzard -- a structure between the mouth and the stomach -- with the help of stones.
Sea horses, pipefish, and adult sturgeon have no teeth of any type. In fish, Hox gene expression regulates mechanisms for tooth initiation. While both sharks and bony fish continuously produce new teeth throughout their lives, they do so via different mechanism.
Baleen whales do not have teeth. Baleen whales have two blowholes, and they tend to be larger than toothed whales. Instead of teeth, whales in this group have special baleen plates with bristles that serve their dental needs.
In fact, the whale shark and basking shark are both unique sharks because these species do not have a normal sharklike tooth. Instead, they have filters in their large mouths that are a lot like how a whale uses its mouth to gather up small plankton to eat.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood.
Yes, ants have teeth, as anyone who has ever stepped on an ant mound can attest. These specialized structures, technically called “mandibular teeth” because they are attached outside of their mouths, are made of a network of material that tightly binds individual atoms of zinc.
The peacocks have no teeth. As being a bird they have their beaks instead of teeth. Moreover, Ostrich also does not have teeth, they eat stones which help to grind their food when it reaches the gizzard.
In their lifetime, Elephants work their way through six sets of molars. As one set wears out, another moves up from the back of the mouth to replace it until the final set wears out and the elephant dies of starvation, no longer able to chew up plants.
- When you see a hippopotamus opening its mouth, it seems as though they have only four teeth! But they actually have 40 pearly whites.
It has no teeth, so the platypus stores its "catch" in its cheek pouches, returns to the surface, mashes up its meal with the help of gravel bits hoovered up enroute, then swallows it all down. The female platypus lays her eggs in an underground burrow that she digs near the water's edge.
While sharks certainly do have a lot of teeth and are continuously regrowing ones that fall out, the answer is actually catfish, with the toothiest species sporting a staggering 9,280 teeth.
The Great White Shark: Yes, this petrifying villain of the Jaws' series happens to have some of the strongest teeth on the planet. Being the largest predatory fish, it has around 3,000 teeth arranged in rows on its jaws.
They react differently when external stimuli are applied while sleeping and while awake. But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
Spiders have no teeth and rely on the venom to liquefy their prey in order that their stomachs, known as sucking stomachs, can draw in the meal.
Flies don't have teeth. They can't take a bite out of our food, so they have to spit out some enzyme-rich saliva that dissolves the food, allowing them to suck up the resulting soup of regurgitated digestive fluids and partially dissolved food.
Leech: The interior structure of a leech is divided into 32 different segments, each of which has its own brain.
The only part of the body that has no blood supply is the cornea in the eye. It takes in oxygen directly from the air.
What animal has purple blood? Peanut worms, which are a kind of marine worm, have purple blood. This is due to the presence of hemerythrin, an oxygen-binding protein.
While sharks do have teeth, their teeth are embedded in their lips, not in the jaws. Scientists have discovered that the exterior of the shark jaw has some structure that may provide necessary force.
Shark teeth buried in sediments absorb surrounding minerals, turning them from a normal whitish tooth color to a deeper color, usually black, gray, or tan. The fossilization process takes at least 10,000 years, although some fossil shark's teeth are millions of years old!
They are considered one of the most abundant living shark species in the ocean, but are harmless to humans. Dogfish sharks make up the second largest order of sharks at 119 species.
