Teenage elephants need a father figure | BBC Earth (www.bbcearth.com)

I hadn’t previously worried about gangs of juvenile delinquent elephants.

When Gus Van Dyk was an ecologist at Pilanesberg National Park, South Africa, he was worried by a series of attacks on the park’s rhino. The prime suspects were a group of adolescent male elephants (their teenage years are the same as ours – between 12 and 20 years old) who were clearly experiencing heightened aggression – in ‘musth’.
