These two underwater dwellers are certainly adapt to their living conditions! Both the Dolphin and the Shark sleep, hunt, breath and eat all under water. Both known and liked for very different things, the Bottle Nose Dolphin is a love-able and playful under water mammal while the shark, a cold blooded, menacing under water hunter.

With hundreds of years surviving in the great big seas and oceans, which of these two would we bet is more adapt at seeing all things under water? Let’s look at the facts!

Great White Shark

Known as the ocean’s top hunter, sharks have almost a 360 view of the world around them because of the placement of their eyes. With a retina divided into two, sharks eyes can adapt to a lot of light during the day to low light at night. This means extra early breakfast or last night snack – no problem for sharks!

Fun facts – sharks eyes are 10x more sensitive to light than humans AND they can see objects (likely their next meal) 50 – 70 feet away. They also have two major blind spots – right in front of their snouts and right behind the head before the body.

Don’t expect sharks to react to colour – they are essentially colour blind. While they can detect light and the absence of…when it comes down to colours, they are unable to detect the various shades in the rainbow or beyond.

Sharks have a very unique ability to roll their eyes back inward into their sockets for protection – kind of like a turtle does with it’s shell. For a shark, their eyes are extremely important – when it feels threatened or under attack by another sea animal or a structure under water the eyes are the primary focus of protection, to lose that would make the shark extremely vulnerable to predators.

Auto-correct features built right into each eye ball and 300 degree view

Bottle Nose Dolphins

Dolphins are unique water mammals that essentially have auto-correct built into their eyes. The lenses and cornea work to quickly adjust for the difference in refraction to allow for the Dolphin’s rare ability to see all the scenic views of the underwater clearly, as well as land and the world outside of water. Without this ability – the view of the world outside of the water for these adorable sea creatures would be very different, Dolphins would essentially be near-sighted.

Fun fact – because of the placement of their eyes, Dolphins have a 300 degree panoramic view of their surroundings. They can see in front of them, beside and behind them at any given time. Unlike humans whose eyes work in tandem – Dolphin’s eyes work independently. While one pupil might be keeping a watchful eye out for predators, the other could be resting and closed. This is true during ‘sleeping’ periods for Dolphins as they always keep one eye open to protect against danger or to stay alert and go up for air if needed.

The area around the dolphins eyes are extremely sensitive much like the area around its blowhole, great care is taken to protect and avoid damage to their eyes. Much like sharks – a Dolphin can’t see what colour bathing suit your wear so don’t both asking them if they like that shade of purple on you!

Who takes first place? While we don’t doubt in a combat situation the great white shark would probably kick butt – but when comparing vision and eye ability, we have to give the gold to the under dog. Our pick is the bottle nose dolphin! Think about it, who wouldn’t love to be able to see clearly both under and out of water? Plus, the independent eyes looking at two different things at the same time…kind of creepy but kind of cool at the same time! What do you think?
