How good is a crocodiles night vision?
At night, crocs have good eyesight. crocodiles use their eyes to focus on a panoramic view, instead of a single point of view. Crocodiles also have excellent hearing. This is the same as a human’s hearing range of 20-100 dB, but it is much higher than that of most other animals, such as dolphins, whales, and birds.
The reason for this is that crocodyliforms have two types of eardrums, one for hearing and the other for smell. When a sound is detected, the inner ear sends a signal to the olfactory bulb, a part of the brain that is responsible for detecting odors. If the signal is strong enough, it triggers the release of chemicals in the nasal cavity.
These chemicals, in turn, stimulate the trigeminal nerve, causing a sensation of tingling, itching, burning, or pain. In humans, this sensation is known as tinnitus.
