Dwarf Crocodile (Osteolaemus tetraspis) Fact Sheet: Diet & Feeding

Diet

Carnivore

  • Opportunistic predator (from Riley and Huchzermeyer 2000)
    • Diet varied (Pauwels et al. 2007)
    • Includes a variety of invertebrates and small vertebrates
  • Consume aquatic and terrestrial items (Pauwels et al. 2007; Riley and Huchzermeyer 2000; Waitkuwait 1989)
    • Invertebrates are the primary food source, most studies (Eaton 2010a)
      • Millipedes and beetle larvae commonly consumed in southwestern Gabon (Pauwels et al. 2007)
    • Reptiles, amphibians, and small mammals also taken (Pauwels et al. 2007; Riley and Huchzermeyer 2000; Waitkuwait)
    • Fish commonly consumed (Eaton 2010a)
  • Plant debris often found in stomach contents (Riley and Huchzermeyer 2000)
  • Rocks (from Pauwels et al. 2007)
    • Gastroliths found in stomach content samples
    • Function
      • Not likely to aid in buoyancy
        • Mass suggests an alternative function
      • Possibly assist with food processing
      • May aid against parasites
