Fun Facts

  • Palpebrosus means “bony eyelids”
  • While most crocodilians have yellow eyes, this species has brown eyes.
  • Dwarf Caimans are often distinguished by the unusual shape of their head. The skull sits very high and the snout makes an upturned curl. The structure of the skull suggests that they make use of burrows as shelter during the day.
