Extreme suction helps elephants suck up water quickly, and to hold water and food in their trunks. Extreme suction enables elephants to inhale water at speeds nearly 30 times faster than humans exhale air during a sneeze.
New Scientist magazine, on 2 June 2021, announced recent research results on the effectiveness of elephants using extreme suction. Elephants use their trunks, which weigh more than 100 kilograms (220 pounds), in a variety of ways: to forage through vegetation for food, to drink, and even as a snorkel when wading through deep water.
To better understand the trunk in action, scientist Andrew Schulz at the Georgia Institute of Technology in America, and his colleagues, filmed a 34-year-old female African Savannah Elephant (Loxodonta africana) while she completed a series of tests at a zoo in Atlanta.

What are bird nostrils and nares?
Bird nostrils and nares are nose holes, or openings, that enable a bird to breathe.
There are two holes – one on each side of a bird’s beak.
The beaks of birds are different sizes and shapes – long or short, small or large, straight or curved, and wide or thin. Therefore, the nares are in different places for different species of birds.

The black hair of males becomes silver as it ages (and they are called silverbacks). It has a short nose, a large eyebrow ridge, large nostrils, small dark eyes, and small ears. It has no tail.
It has five digits on each hand and foot, which have fingernails and toe nails. Its thumbs are large. It has long arms. It walks with a hunched movement, with the knuckles of its hands touching the ground.

The White Rhinoceros (Ceratotherium simum) is also called the Square-Lipped Rhinoceros. Most rhinos in zoos are Southern White Rhinoceroses. There are only two Northern White Rhinoceroses (Ceratotherium cottoni) left in the world – two females – and they are in the Ol Pejeta Conservancy in Kenya under 24-hour armed guard. There were three Northern White Rhinos, but Sudan, a male, died of old age on 19 March 2018 at the age of 45.
The White Rhinoceros is an African mammal and the largest rhinoceros in the world. It is grey and hairless, except for hair on the ears and tail tuft.
