Adult African elephants typically weigh between 4,000-7,000 kg, with males averaging around 6,000 kg (13,200 lbs). Asian elephants are somewhat smaller at 4,000-5,000 kg.
What is the heaviest animal?
The blue whale is the heaviest animal ever known, with adults weighing 140,000-190,000 kg (150-210 tons). Their hearts alone weigh about 400 kg.
Can I use this for density calculations?
