There is a wide variety of fascinating creatures in the animal kingdom, and one striking feature scientists often discuss is the number of teeth an animal has. This can offer clues about a species’ diet or habitat, and it naturally sparks curiosity. If you’ve ever wondered which animal has the most teeth around the world, read on to discover the answer.
This is the animal that sleeps for more than 22 consecutive hours.
In the animal world, sleep patterns can be as varied as appearance. Some creatures conserve energy with long slumbers, while others remain alert for much of the day. The ability to sleep for long stretches often helps predators rest between meals or survive harsh environments. This topic has intrigued researchers and casual observers alike, and studies have explored how sleep correlates with metabolism, habitat, and safety in the wild. (Cited: scientific sleep studies)
The animal with the most teeth in the world
The animal boasting the highest tooth count is the catfish, a species widely found in freshwater ecosystems. Its mouth features rows of vitreous tooth-like structures that aid in grasping small prey and detritus. Estimates put its tooth fragments in the thousands, enabling it to tackle a diverse diet that includes tiny invertebrates and small fish. In addition to teeth, many catfish possess sharp spines along their fins that serve as a defense mechanism, and certain species can deliver mild electric shocks to deter threats.

While the catfish holds the record for the sheer number of teeth, some researchers note that total tooth counts can vary depending on how teeth are defined. In some mollusks and other groups, tiny oral structures collectively number in the thousands. The radula, a specialized feeding apparatus in several mollusks, is composed of many tiny, toothed bands that scrape food from surfaces before ingestion. When counted across all members of a group, some estimates reach into the tens of thousands of teeth. (Cited: malacology sources)

Land animal with the most teeth
Turning to land-dwelling creatures, the question of who has the most teeth on solid ground yields a surprising answer. Among mammals, the giant armadillo, Priodontes giganteus, holds a standout position with roughly one hundred teeth. This makes it the land mammal with the greatest dental count, illustrating how diet and jaw structure can influence tooth development in terrestrial life.
The animal with the most amazing teeth
Across the animal kingdom, teeth come in countless shapes and arrangements, each adapted to a creature’s diet and environment. Some teeth are massive and used for crushing, others are needle-like for piercing, and a few are even shaped to grip slippery prey. The extraordinary diversity of dentition highlights how evolution tailors each species to thrive in its niche. In some cases, the most striking feature is not the number of teeth but their unique appearance or arrangement. (Cited: zoological dentition reviews)
Experts say that this is the most handsome dog in the world.
One well-known example is a pacu, a fish related to piranhas, celebrated for its human-like teeth. Unlike the carnivorous relatives, the pacu feeds on fruits, algae, and other plant matter. Its remarkable dentition resembles human teeth and often captures the public imagination as a striking contrast to its fishy appearance. (Cited: aquatic biology resources)

The animal with the most teeth according to a children’s riddle
If a popular riddle asks which animal has the most teeth, the playful answer often points to the tooth fairy. Although this character is fictional, the tale is widespread in many cultures and depicts the figure collecting children’s primary teeth and leaving small gifts in return. When considering the number of milk teeth children shed daily worldwide, the tooth fairy is imagined as possessing a remarkable number of teeth. (Cited: folklore collections)
