How Much Do You Know About Elephants?

Study Notes

Elephants are the largest existing land animals.
There are three living species: African bush elephant, African forest elephant, and Asian elephant.
They are the only surviving members of the family Elephantidae and the order Proboscidea.
Elephants have distinctive features such as a long proboscis called a trunk, tusks, large ear flaps, pillar-like legs, and tough but sensitive skin.
They are herbivorous and found in different habitats, including savannahs, forests, deserts, and marshes.
Elephants have a fission-fusion society and live in family groups led by the oldest cow, known as the matriarch.
Adult bulls mostly interact with family groups when looking for a mate.
Elephants can live up to 70 years in the wild and communicate by touch, sight, smell, and sound.
African bush elephants and Asian elephants are listed as endangered and African forest elephants as Critically Endangered by the International Union for Conservation of Nature (IUCN).
The biggest threat to elephant populations is the ivory trade, as the animals are poached for their ivory tusks.
Proboscideans evolved from plantigrade to digitigrade stance with cushion pads and sesamoid bone support
Cheek teeth became larger and more specialized, especially after elephants switched to C4-grasses
Elephants have tusks that vary in shape depending on the species
Some proboscideans experienced insular dwarfism on islands
Elephants are the largest living terrestrial animals
The elephant's skull is resilient and contains air cavities
The trunk is the elephant's most important and versatile appendage
Elephants can inhale at over 150 m/s and can hold up to 8.5 L of water in their trunks
Losing the trunk would be detrimental to an elephant's survival
Elephant teeth are polyphyodonts and are replaced throughout their lives
Elephant tusks grow continuously at a rate of 17cm per year
Tusks are used for digging, debarking, moving trees, and fighting
African elephants have tusks in both males and females, while Asian males have larger tusks than females
Elephants have thick, sensitive skin that requires regular mud baths for protection
Their limbs are positioned vertically under their body to support their weight, and they can move forwards and backwards but cannot trot, jump, or gallop
The elephant brain is the largest of all terrestrial mammals and has well-developed cerebrum and cerebellum
The heart of an elephant weighs 12-21kg and has a double-pointed apex
Elephants have an S-shaped penis that can reach a length of 100cm and a diameter of 16cm at the base
The female's mammary glands are located between the front legs, and the vulva is located between the hind legs
Elephants have a unique organ called the temporal gland, which is associated with sexual behavior and males secrete a fluid from it
Elephants are homeotherms, maintaining an average body temperature of 36°C.
They are herbivorous, consuming up to 150 kg of food and 40 L of water per day.
Elephants are keystone species, having a significant impact on their environment.
Female elephants live in tight-knit family groups led by the eldest female, the matriarch.
Male elephants spend more time away from their family groups as they mature.
Dominance hierarchy exists among males, and they form long-term relationships.
Adult males enter a state of increased testosterone known as musth.
Elephants are important seed dispersers and can create waterholes used by other animals.
They tend to stay near water sources and go on seasonal migrations in search of food, water, minerals, and mates.
Elephants can have a negative impact on ecosystems, such as soil compaction and erosion.
