See The World Through My Eyes

Bald eagle

Spiders with 8 eyes, eagles that can focus on two objects simultaneously – no two animals see the same thing. Here are just a few examples.

Bald Eagles
Talk about eyes in the back of your head! Eagles can focus on objects in front and beside them at the same time thanks to having two centres of focus. Their eyes are four times as sharp as human eyes. From a fixed position at 1,000 feet above the ground, they can spot prey in an area just under 8 km squared. An inner eyelid, called a nictitating membrane, slides across their eye every few seconds to wipe away dust or dirt.

Tawny Owl

Butterflies & Moths
Some butterflies and moths have colourful patches on their wings that resemble eyes. Scientists speculate that they are used to frighten or distract potential predators. Owl butterfly have a bad reputation for getting drunk on fermented fruit.


Fiddler crabs have almost-perfect all-round vision but, because their eyes don’t move, they use different parts of their eyes in different ways. Their sharpest vision is immediately in front of them and is used to identify and communicate with potential mates. Their overhead vision is limited to perceiving light and dark but is more than adequate for recognizing a seagull swooping down from the sky.


Damselflies & Dragonflies
Huge eyes take up most of the space on dragonflies’ and damselflies’ heads. By piecing together images from their 20-30,000 individual lenses, they can see what’s happening all around them, essential for locating and capturing prey while hovering in mid-air. They also have 3 simple eyes on their forehead that can detect light intensity.


Fish can’t close their eyes as they don’t have eyelids. Some have transparent nictitating membranes they can pull down to protect their eyes, while others have light-activated pigments in their eyes that turn darker when exposed to a bright light.

Bull frog

Frogs & Toads
Now this is amazing! Have you noticed that frogs and toads shut their eyes when eating? Their eyes actually move backwards, helping the tongue to push food down their throat.

Barred owl (?)

Owls’ eyes are shaped like tubes rather than spheres and are fixed in place, but they can turn their necks up to 135 degrees in either direction. A large retina and an abundance of rods ensure that owls can take advantage of whatever light is available at night. The rod cells are connected differently than human rod cells so they’re able to pick up edges, movement, and silhouettes in dim light.


Pronghorn have large eyes (36 mm in diameter) near the back of their head. They can spot movement up to 6.5 km away and can view objects within a 300-degree arc without moving their head or eyes.

Fishing spider

Most spiders have 8 eyes, but they’re not always arranged in the same way. For example, fishing spiders have 2 rows of 4 eyes, while wolf spiders have 3 rows of eyes (4-2-2). “Daylight hunting spiders use their two pairs of ‘side’ eyes to detect the motion of their prey. The spider then uses the two most central eyes to focus on their prey. The pair of eyes next to these are used for depth perception. When the target is close enough, these eyes let the spider know when to strike.”

In the News
The City of Saskatoon's Green Strategy is long overdue, but action must match policy. It's fine to talk about conserving biodiversity and increasing interconnections, but it falls flat in face of City Council's refusal to lower speed limits through the Small Swale.

The City of Saskatoon has adopted Vision Zero. The challenge now is to make sure it works by designing streets to protect cyclists and pedestrians.

Could we use LED lights to avoid bird collisions with planes, buildings, etc?

“Ultimately, bringing our civilization back within planetary boundaries is going to require that we liberate ourselves from our dependence on economic growth—starting with rich nations. This might sound scarier than it really is. Ending growth doesn’t mean shutting down economic activity—it simply means that next year we can’t produce and consume more than we are doing this year. It might also mean shrinking certain sectors that are particularly damaging to our ecology and that are unnecessary for human flourishing, such as advertising, commuting, and single-use products.”

And, for the techies in the crowd, how and why to build a low-tech website.
