SNAKE EYES - How Snakes See  -  by MrClean1982

How snakes see is often misunderstood. For instance it is a misconception that snakes are almost blind. While their vision isn’t as acute as a persons they have other tools that work in harmony with sight to give them a very robust image of the world around them.

Their hearing, despite a lack of external ears, is superb.

They have an excellent sense of smell, so acute that it allows them to track the exact direction their prey is going turn by turn.

In addition there some snakes, the most infamous of which are the pit vipers, that have a special infrared vision.

Here are some interesting tidbits of information about a snakes vision.

Snakes have cones in their retinas; cones is what allows us to perceive color—in snakes it is not as vivid nor wide a range. Think in terms of hues and shades

They have trouble seeing things that aren’t moving.

A snake is very near sighted

It is NOT true that you can tell a venomous snake by the shape of its pupils

Snakes rely on a filter over the lens of their eyes that can not be penetrated by the uv wave length

A snake has eyes with a telescoping lens. They can move the lens forward and backward (in and out) with muscle contraction/relaxation

A snake has no eye lids. They have a clear scale over each eye that comes off when they shed their skin

In general snakes can see better at night because their rods are more highly developed than the cones. Which is the opposite of you and I. T

Snakes are not able to move their eyes, so they can’t look around without moving their heads

One sign a snake is going to shed is its eyes become opaque about 5 to 7 days before it happens

Sometimes a shedding snake will not shed the scale on its eyes. This is often a sign that the humidity is too low

"they were highly curious. they would come within inches of me with great curiosity, but no aggression," notes brian skerry, who was photographing southern right whales in the auckland islands marine reserve.

said brian, i’ve been diving for about thirty years, and i can honestly say that i’ve had some amazing encounters with sharks, squids, and other whales. but the encounter with the right whales in the auckland islands was probably the best thing i’ve ever done.”

brian recounts how, “i was swimming alongside this huge whale, kicking as hard as i can to keep up…but i had to take a break, so i stopped and kneeled down on the bottom. instead of continuing, the whale stops and turns and waits for me, as if to say ‘i’ll wait for you to catch your breath.’
