Did you know that ...

Due to their poor eyesight and murky aquatic environment, electric eels have developed a keen sense of hearing that is aided by a modified vertebrae between their inner ear and swim bladder that detects and interprets pressure changes in the water. Because of their eyesight, they navigate and sense prey using discharges as a kind of radar or echolocation. Electric eels aren't actually eels but a type of knifefish.
