💡 Everyday Comparisons for Size, Mass & Speed

  • 💡 In villages in Sierra Leone and Nigeria, people catch it with snares and harpoons for meat; its meat, hide, bones, and oil are used.
  • 💡 Its maximum weight of 750 kg is about thirty-seven and a half 20 kg bags of rice (Comparison).
  • 💡 Eating up to 8,000 kg of aquatic plants per year works out to just over 20 kg a day—about one bag of rice worth of plants daily (Comparison).
