Do dolphins see in color?

Dolphins have limited color vision and poorer visual acuity, or clearness of vision from a specific distance, both in air and under water than primates.

What does a dolphins vision look like?

Bottlenose dolphins have a double slit pupil allowing for similar visual acuity in air and water. Their eyes are adapted to mitigate varying light intensities. Studies show that the visual acuity of dolphins is similar or below the range of many terrestrial animals.

How do dolphins view humans?

The science makes one fact undeniably clear: wild dolphins of some species are noted for seeking out social encounters with humans. There is no doubt that these animals are exhibiting inquisitive behaviour, which lends weight to the idea that dolphins do in fact seek out human contact with some regularity.

Does dolphin have good eyesight?

Combined with their excellent eyesight and sonar like system to process visual information underwater – called echolocation, dolphins have a great advantage in the ocean compared to other marine life that rely on sight only.
