12. Feeling Blue but Not Sad

Dolphins may be feeling blue, but not because they're sad: Their color vision is limited to the blue/green spectrum due to having only one type of cone cells. However, they more than make up for it with their highly developed echolocation system which lets them "see" objects up to 80 meters away underwater by emitting sound waves and interpreting the echoes.

13. Pioneers of Sonar Technology

Dolphins may not have discovered sonar technology, but they sure did perfect it before we submariners got the memo! These aquatic jesters can delicately pick up a tune even miles away: With their high-frequency clicks, echolocation allows them to detect minuscule objects as small as 8 cm from distances of over 110 meters, all while navigating the underwater world with unerring precision.
