Exploring the Fascinating Characteristics of Crocodilians

Crocodilians possess highly developed senses, including smell, hearing, and eyesight. Their bodies are covered in non-overlapping scales called schoots, which aid in thermoregulation. The head and teeth vary among species, reflecting their diet and hunting strategies. Crocodilians use ambush techniques to capture prey and have a unique digestive system that allows them to survive on minimal food. Their circulatory system enables them to dive for extended periods by reducing heart rate and shutting off blood flow to the lungs.
