ALL ABOUT HIPPO

1. Scientific Classification

Closest relatives: Despite looking like pigs, hippos are actually closely related to whales and dolphins!

Size:
- Males: 1,500–3,200 kg (3,300–7,000 lbs)
- Females: 1,300–1,800 kg (2,800–4,000 lbs)
Length: 3.5–5 meters (11–16 feet)
Height: 1.5 meters (5 feet) at the shoulder
Skin: Thick, grayish-brown skin that secretes a pinkish "blood sweat", which acts as a sunscreen and antibacterial agent.
Mouth & Teeth:
- Hippos have huge mouths that open 150 degrees!
- Their canine teeth (tusks) grow up to 50 cm (20 inches) and are used for defense, not eating.

Found in rivers, lakes, and swamps across sub-Saharan Africa.
Need access to freshwater to keep their skin moist and regulate body temperature.
Live in groups called pods, ranging from 10 to 30 individuals.

Nocturnal grazers: Hippos spend the night on land eating grass, consuming 40 kg (88 lbs) of food per night.
Semi-aquatic: Spend most of the day submerged in water to stay cool.
Fast runners: Despite their size, they can run up to 30 km/h (19 mph) on land!
Highly territorial in water: Males fight fiercely to defend their area.

Live in groups (pods) led by a dominant male, with females and young.
Aggressive and territorial—hippos are responsible for more human deaths in Africa than lions or crocodiles.

Herbivores:
- Eat mainly grass (not fish, despite being in the water).
- Can eat water plants and fallen fruit occasionally.
Huge appetite: Consume 40 kg (88 lbs) of vegetation per night.

Mating occurs in water, with dominant males controlling access to females.
Gestation period: 8 months.
Birth:
- One calf (baby hippo) is born underwater, weighing 25–50 kg (55–110 lbs).
- Calves nurse underwater and stay close to their mothers for up to 2 years.
Lifespan:
- Wild: 40–50 years.
- Captivity: Up to 60 years.

Status: Vulnerable (IUCN Red List).
Main threats:
- Habitat loss due to agriculture and human expansion.
- Poaching for ivory (teeth) and meat.
- Climate change affecting freshwater sources.
Conservation efforts:
- Protected in national parks and reserves.
- Anti-poaching laws in some countries.

Can hold their breath for 5 minutes underwater.
Eyes, ears, and nostrils are on top of their heads, allowing them to stay submerged while still sensing their surroundings.
Despite their size, they can swim gracefully and even walk on riverbeds.
Powerful bite: Their bite force is 1,800 psi, strong enough to crush bones!
Ancient relatives of whales: Hippos and whales share a common ancestor from 55 million years ago.

Ancient Egypt: Hippos were associated with the goddess Taweret, who protected women during childbirth.
Myths & Legends: In African folklore, hippos are often depicted as powerful, wise, or dangerous creatures.
