The Mysteries of the Crocodile’s Brain
Crocodiles, one of the world’s most formidable predators, possess more complexity in their brains than any other reptile. They use senses such as smell and hearing to stay alive during hazardous situations.
They use their eyes to monitor their environment and avoid danger. This survival skill enables them to survive in wetlands, swamps and jungles around the world.
Crocodiles possess an eye that can detect where they are underwater, even when submerged. This extraordinary sense of depth has been one of their most remarkable adaptations for life in the wild, according to scientists.
Crocodiles possess the capacity to recognize shapes of objects like rocks and pebbles even in low light levels, an adaptation that allows them to hunt in murky waters where they cannot see the bottom.
Crocodiles possess an acute sense of danger, and will respond by raising their blood pressure, breathing harder and pumping more oxygen into their muscles and heart to keep them working at full capacity.
Crocodiles may use this technique to detect other animals’ presence. For instance, if a crocodile hears an alligator approaching, it can turn its head away and swim away, thus avoiding an attack.
Crocodiles use their eye to locate prey. This ability enables them to sense the motion of fish swimming in a school, enabling them to identify individual fish and locate them quickly and accurately.
Crocodiles have evolved an ability to recognize various movements and track their prey, which helps them survive in waterlogged areas such as swamps or jungles where they cannot see the bottom.
Until recently, no one knew why the bumps on a crocodile’s skin existed. Herpetologists speculated that they might be pit glands or parts of its nervous system.
Science has now discovered that these nodules are actually sensory organs – miniature pressure sensors that pick up vibrations from a drop of water.
They use these sensations to locate a drop of water and tell when it is near the surface or deep within it. Researchers refer to these receptors as “dome pressure receptors,” or DPRs for short.
Crocodiles possess DPRs as well as nerve endings that can sense salinity and temperature. When the eye detects an increase in salty water, it sends signals to its brain to raise blood pressure and respiration rates accordingly.
Crocodiles can detect vibrations of objects with their feet, which is especially useful in dense jungle where trees often fall into waterways.
Crocodiles rely on this adaptation for survival in the jungle, often found in tropical rivers and swamps. It helps them locate prey easily even in murky waters where other predators may attack. This adaptation helps ensure the crocodile’s safety when hunting in unfamiliar territory.
