Interactions between ticks and crocodilians (crocodiles, alligators, caiman, and gharials) are poorly studied but may have significant bearing on the ecology and health of these reptiles. The first record of tick infestation of the saltwater crocodile (Crocodylus porosus) is reported along with the first case of infestation by Amblyomma cordiferum on Cuvier's dwarf caiman (Paleosuchus palpebrosus). A review is also provided of tick-crocodilian interactions with a concise host-parasite index.
