A large whale could theoretically manage it, although blue whales have a surprisingly narrow oesophagus and can’t swallow anything larger than a melon. In reality, the only animal large enough to swallow you whole without killing you first, or in the process, is a sperm whale.

Common hippos, also known as river hippos, are very rotund animals and are the third largest living land mammals, after elephants and white rhinos, according to the African Wildlife Foundation. They grow to between 10.8 and 16.5 feet (3.3 and 5 meters) long and up to 5.2 feet (1.6 m) tall at the shoulder. The average female weighs around 3,000 lbs....
Common hippos live in sub-Saharan Africa. They live in areas with abundant water, as they spend most of their time submerged to keep their skin cool and moist. Considered amphibious animals, hippos spend up to 16 hours per day in the water, according to National Geographic. Hippos are social beasts, hanging out in groups called schools, bloats, pod...
Hippos have a healthy and mostly herbivorous appetite. Adults eat about 80 lbs. (35 kg) of grass each night, traveling up to 6 miles (10 km) in a night to get their fill. They also eat fruit that they find during their nightly scavenging, according to National Geographic. If food is scarce, hippos can store food in their stomachs and go up to three...
Female hippos have a gestation period of eight months and have only one baby at a time, according to the San Diego Zoo. At birth, the calf weighs between 50 and 110 lbs. (23 and 50 kg). For its first eight months, the calf nurses while its mother is on land, or it swims underwater to suckle. When it dives, the calf closes its nose and ears to block...
The hippopotamus is considered the world's deadliest large land mammal. These semiaquatic giants kill an estimated 500 people per year in Africa, according to the BBC. Hippos are highly aggressive and are well-equipped to deliver considerable damage to anything that wanders into their territory. For example, in 2014, a hippo attacked a small, unsus...
According to the International Union for Conservation of Nature(IUCN), the common hippo isn't endangered, but it is vulnerable to extinction. The IUCN estimates that between 115,000 and 130,000 common hippos remain in the wild. Poaching and habitat loss reduced the hippo's global numbers during the late 1990s and early 2000s, but the population has...

Hippos can store large quantities of food within their stomachs, which helps sustain them during periods when food is scarce. This storage capacity allows them to go without eating for several days or even weeks, depending on the availability of food resources.
Hippos can store two days' worth of grass in their stomachs and can go up to three weeks without eating. Hippos vocalize on both land and in the water and are the only mammals that make amphibious calls.
May 7, 2024 · Low metabolic rate allows survival for many weeks without food. Eat approximately 1-1.5 % of body weight per day. At least 2.5% of body weight for many other ungulates such as cattle, white rhinos. Adult hippo consumes 25-40 kg (55-88 lbs) vegetation/day.
Oct 8, 2024 · Hippos, however, eat relatively little vegetation for their size (about 35 kg [80 pounds] per night), as their energy requirement is low because they are buoyed in warm water much of the time. Hippos do not chew cud but retain food for a long time in the stomach, where protein is extracted by fermentation.
