Forest elephants have a lifespan of about 60 to 70 years and mature slowly, coming to puberty in their early teens. [52] Bulls generally pass puberty within the next year or two of females. Between the ages of 15 and 25, bulls experience "musth", which is a hormonal state they experience marked by increased aggression. The male secretes fluid ...

Dwarf elephants of uncertain descent lived in Crete, Cyclades and Dodecanese, while dwarf mammoths are known to have lived in Sardinia. [26] The Columbian mammoth colonised the Channel Islands and evolved into the pygmy mammoth. This species reached a height of 1.2–1.8 m (4–6 ft) and weighed 200–2,000 kg (440–4,410 lb).
The population of rainforest elephants was lower than anticipated, at around 214,000 individuals. Between 1977 and 1989, elephant populations declined by 74% in East Africa. After 1987, losses in elephant numbers hastened, and savannah populations from Cameroon to Somalia experienced a decline of 80%. African forest elephants had a total loss ...
Analysis of nuclear DNA sequences indicates that the genetic divergence between African bush and forest elephants dates 2.6 – 5.6 million years ago. The African forest elephant was found to have a high degree of genetic diversity, likely reflecting periodic fragmentation of their habitat during the changes in the Pleistocene. [12]
Elephantidae is a family of large, herbivorous proboscidean mammals which includes the living elephants (belonging to the genera Elephas and Loxodonta), as well as a number of extinct genera like Mammuthus (mammoths) and Palaeoloxodon.

In a 2010 study, it was estimated that in India alone, over 400 people were killed by elephants each year, and 0.8 to 1 million hectares were damaged, affecting at least 500,000 families across the country. [99] [100] [101] Moreover, elephants are known to destroy crops worth up to US$2–3 million annually. [102]
