Emergence behaviour of yacare caimans (Caiman Crocodiles yacare) in the Brazilian Pantanal
We studied the emergence and basking behaviour of Pantanal caimans (Caiman crocodilus yacare) in relation to temperature. In the cold season, caimans were exposed to the sun, and air temperatures higher than water temperatures suggest that emergence behaviour may be due to thermoregulation. In the d...
