Summary of Transcript:
The video features Callan Mulvaney, a senior biologist at Adventure Aquarium, discussing the teeth of the resident hippos named Jenny and Button. Mulvaney explains that hippos have about 40 teeth, including their incisors and canines made of ivory, which are used for defense and combat. Hippos use their molars to grind and chew their food, which they enjoy. The aquarium participates in a voluntary behavior called Dremel, where the hippos hold their mouths open for a sander to be used on the tips of their tusks to maintain their teeth. Additionally, fish in the exhibit act as dentists, helping to clean the hippos’ teeth.

Title: The Fascinating World of Hippopotamuses
Introduction
Hippopotamuses are large, barrel-shaped mammals that are native to Africa. They are known for their massive size, powerful jaws, and love for water. But did you know that a hippo can open its mouth 180 degrees? This article will explore the fascinating world of hippopotamuses and uncover some of their most exciting features.
Body
Size and Physical Appearance
Hippopotamuses are one of the largest land animals in the world. They have massive bodies shaped like barrels with short, stocky legs that are powerful enough to carry their weight. Adult hippopotamuses can weigh up to 3,000- 4,000 pounds and grow up to 15 feet in length.
Despite their large size, hippopotamuses have very little hair on their skin. They have thick, hairless skin that is gray or brown. Their skin secretes a natural sunscreen substance that protects them from the sun’s rays.
Jaw Strength and Teeth
Hippopotamuses are known for their powerful jaws and their massive teeth. Their bite force is so strong they can easily crush a crocodile’s skull with one bite. They have enlarged canine teeth and large incisors that are designed for biting and grinding.
Hippopotamuses have multiple sets of teeth that grow throughout their lifetime. Their teeth are continuously replaced, with new ones replacing old ones. A hippo’s teeth can grow up to 30 centimeters long, and when they become too worn or damaged for feeding, they fall out and are replaced by new ones.
Mouth Opening
In addition to their impressive teeth, hippopotamuses can open their mouths incredibly wide. They can open their mouth 180 degrees, revealing their large teeth and powerful jaws. This wide-mouthed ability has helped hippopotamuses evolve into one of the most dangerous animals in Africa.
Despite their fearsome reputation, hippopotamuses are vegetarian and feed exclusively on grass, leaves, and fruits. Their massive jaws and teeth enable them to graze for several hours throughout the day, consuming up to 150 pounds of vegetation in one sitting.
Habitat and Behavior
Hippopotamuses are semi-aquatic and usually near rivers, lakes, and swamps. They are good swimmers and can hold their breath for several minutes underwater. They spend most of their day underwater, venturing out in the evening to graze.
Hippopotamuses are also social animals and usually live in groups of up to 30 individuals. A dominant male or female usually leads these groups, and they have a strict hierarchy. During the mating season, males will compete for breeding rights with female hippopotamuses. During this time, aggression levels rise, and fights between males can result in severe injuries or even death.
Conclusion
In conclusion, hippopotamuses are fascinating creatures with an array of unique traits. They are one of the largest land animals, with powerful jaws and teeth that enable them to defend themselves and graze on vegetation. They are semi-aquatic animals that spend most of their day in the water, emerging only at nightfall to feed. Despite their fearsome appearance, they are vegetarian animals and pose no threat to humans unless provoked. So, if you come across a hippopotamus, remember to keep a safe distance and respect its space.
