#FunFact: The Narwhal's Famed Horn is Actually a Tooth --And growing up to an incredible 10 feet long, the narwhal's tooth easily wins Largest Tooth in the Animal Kingdom!
Did you know that Hippopotamuses have the largest teeth of any land animal? Their front incisors can grow to be 1.2 feet in length, and their canines can get to be 1.5 feet!
Hippopotamus – Hippopotamuses have the largest teeth of any land animal. Their canine teeth can grow to be 1.5 feet long and their front incisors grow to be around 1.2 feet long! Saltwater Crocodiles – Lastly, of all the animals in the world, the saltwater crocodile has the strongest bite force.
Snails: Even though their mouths are no larger than the head of a pin, they can have over 25,000 teeth over a lifetime – which are located on the tongue and continually lost and replaced like a shark!
The African elephant has the largest teeth of any animal alive. Their tusks are modified incisors that grow throughout their lives. The tusks serve multiple purposes, including fighting for mates & rooting up food.
Snails have the most teeth of any animal
A garden snail has about 14,000 teeth while other species can have over 20,000.
Fun Fact: Polar bears have about 42 teeth in their mouth, and their bite is twice as strong as a brown bear's. Unsurprisingly, polar bears use their massive teeth to hunt and eat their prey.
Leech: Leech is an annelid. Leech's external and internal segmentation do not correspond to each other. If the internal body is examined, it can be seen that the body is divided into 32 parts or segments which have their own corresponding brain.
We only produce two sets of teeth, milk teeth and permanent teeth that last the vast majority of our lives. Sharks do not rely on two sets of teeth – they have an endless supply of teeth, with a dentition that regenerates constantly throughout life. In some sharks, a new set of teeth develops every two weeks!
Some sharks can shed approximately 35,000 teeth in a lifetime, replacing those that fall out. Sharks have many rows of teeth, and new ones are constantly arriving from the back of the mouth.
Lobsters and crabs have teeth— in their stomachs. These are used to crush its food, but they also have a strange secondary function in ghost crabs: making a noise that wards off predators.
The pattern found instead in most mammals (and believed to be primitive for the group) is diphyodonty, a term derived from Greek words meaning "twofold production of teeth." Most mammals are born with a special set of usually smaller, weaker teeth called milk teeth or deciduous teeth.
That's right! The snail has more teeth than any other animal, a total of 20,000 teeth grace the tongue of the worlds most dentally enhanced snail. Even more shocking is the fact that the aquatic snail has teeth that are stronger than titanium, and are known to be the strongest biological material on Earth!
The Hardest Teeth
The hardest substance ever discovered in nature is the tooth of a limpet (sea snail). They have a tensile strength between 3 and 6.5 gigapascals, breaking the previous record of spider silk at 1.3 GPa.
A polyphyodont is any animal whose teeth are continually replaced. In contrast, diphyodonts are characterized by having only two successive sets of teeth. Polyphyodonts include most toothed fishes, many reptiles such as crocodiles and geckos, and most other vertebrates, mammals being the main exception.
What is tooth enamel? Tooth enamel is the hardest and most highly mineralized tissue in your body. However, it is not a living tissue, which prohibits your teeth from being regenerated or regrown. Once your tooth enamel is chipped or eroded, it is gone for good!
Sharks regularly lose teeth – not because they don't visit the dentist, but because that's a natural thing for these amazing ocean predators. Unlike humans, all sharks are born with teeth. They grow in conveyor-belt rows, with the biggest teeth facing outwards.
The icefish of the Channichthyidae family are unusual in several ways—they lack scales and have transparent bones, for example—but what stands out most is their so-called white blood, which is unique among vertebrates.
Spiders usually have eight eyes but few have good eyesight.
They rely instead on touch, vibration and taste stimuli to navigate and find their prey.
Palentologist have dug up some pretty weird animals, but the Opabinia has to be one of the strangest prehistoric animals ever discovered. It is weird to imagine how an animal can possess five eyes on its head. Even for ancient animals this feature is quite unusual.
Canines. Next to the lateral incisors are our canines, which are the sharpest and longest teeth in our mouths.
Genetic factors cause congenitally missing teeth and this condition is often seen in generations of a family. The most common missing teeth are wisdom teeth, upper lateral incisors, and second premolars/bicuspids.
1) ORCA - Orcinus Orca. The Orca or Killer Whale is the largest member of the dolphin species family and has the sharpest teeth of all animals. Orcas are predators; they are at the top of the food chain in marine life. No other animal preys on orcas; they can even hunt seals, sharks, and dolphins.
