Spectacled Caiman

The Pantanal's everyday crocodilian — bony 'spectacles' between the eyes and a sunbathing riverbank habit.

Least Concern

Caiman crocodilus

Overview

Spectacled caimans are the widespread crocodilians of South American wetlands, named for a bony ridge between the eyes that looks like a spectacle bridge. Smaller than crocodiles, they still rule riverbanks from the Amazon to the Pantanal.

Adds a Brazil reptile distinct from alligator, Nile crocodile, and saltwater crocodile already in the catalogue.

Habitat

  • Rivers
  • Marshes
  • Flooded savanna
  • Lakes

Rivers, lakes, marshes, and flooded savanna across much of northern and central South America, including Brazil's Pantanal and Amazon fringe.

Field notes

Field scale for the Spectacled Caiman: length around 1.5-2.5 m typical; weight 7-40 kg. Typical lifespan: Around 30-40 years in the wild.

When you are scanning habitat, prioritise rivers, marshes, flooded savanna, and lakes. Those settings are where a clean look and a usable photo are most likely.

Quick ID anchor: Olive to brownish crocodilian with a ridge between the eyes like spectacle frames. Confirm with behaviour and habitat before you log the discovery.
