The lungs are attached to the diaphragm, and breathing relies less on the expanding of the ribcage. [77] Connective tissue exists in place of the pleural cavity. This may allow the animal to deal with the pressure differences when its body is underwater and its trunk is breaking the surface for air. [50]
Seeds of various plants will go through the elephant's digestive tract and eventually pass through in the animal's droppings (likely in a new location where they will sprout), thus helping to maintain the spread and biodiversity of the forests. The first scientific description of the species was published in 1900. During the 20th century ...
The African forest elephant is considerably smaller. Fully grown African forest elephant males in optimal conditions where individuals are capable of reaching full growth potential are estimated to be on average 2.09–2.31 metres (6.9–7.6 ft) tall and 1,700–2,300 kilograms (3,700–5,100 lb) in weight.

The African bush elephant has grey skin with scanty hairs. Its large ears cover the whole shoulder, [12] and can grow as large as 2 m × 1.5 m (6 ft 7 in × 4 ft 11 in). [13] Its large ears help to reduce body heat; flapping them creates air currents and exposes large blood vessels on the inner sides to increase heat loss during hot weather. [14]
The Sri Lankan elephant (Elephas maximus maximus) is native to Sri Lanka and one of three recognised subspecies of the Asian elephant. It is the type subspecies of the Asian elephant and was first described by Carl Linnaeus under the binomial Elephas maximus in 1758. [ 1 ]

The Asian elephant (Elephas maximus), also known as the Asiatic elephant, is a species of elephant distributed throughout the Indian subcontinent and Southeast Asia, from India in the west to Borneo in the east, and Nepal in the north to Sumatra in the south. Three subspecies are recognised—E. m. maximus, E. m. indicus and E. m. sumatranus.
