Few investigations of Paleosuchus palpebrosus senses. See Grigg and Kirshner (2015) and other general references (e.g., CSG: “The Crocodilian Body”) for overview of crocodilian sensory systems.
Similar to this crocodilian, the dwarf caiman has a short, high-profile skull.
This head shape is less hydrodynamic than crocodilians with long, slender skulls—but better for crushing and subduing prey (e.g., fish, shellfish, turtles, crabs, etc.).
