Even if they lose sight of a prey they struck, rattlesnakes can still track them.  So that way, they don't have to hold onto their prey while it slowly dies.  If they did, they'd be at risk of injury by a flailing mouse or whatever.  Rattlesnakes have been shown to be able to tell the difference between the trails of unstruck rats and struck rats, opting for the envenomated rat.

That depends upon the snake species and its diet. Snakes that are snake eaters (ophiophagus) often have immunity to the venoms of other snake species, for obvious reasons. So snakes like the Australian Black snakes (Pseudechis sp.) are generally immune to the venoms of the snakes that they prey on. However I found a recent article (quoted below) in which Australian Copperheads (not related to copperheads in the US) succumbed to the venom of another copperhead. Copperheads are known to be snake eaters, which seems odd.

The only person who could answer your question would be either a person who can also see ghosts, or a person who has a ghost-detecting machine.  That person would then need to confirm that the cat/dog sees the ghost that the person is also seeing/detecting.

Bats are not blind. \nThey know it's nighttime because 1) it's dark, sounds change, smells change, usually the temperature drops... how does anyone know it's nighttime? 2) their daily/circadian rhythms tell them so. Anyway, once they're out of their shelters they can see that it's dark, just in case one of them gets confused :-P.\nWhat about phrasing the question the other way around? Bats don't have to fly at night because they're blind; rather they have evolved to occupy an ecological niche that involves crepuscular-nocturnal activity. Some bats took the evolutionary path towards small size and echolocation; those are the ones with small eyes and large ears. It's a matter of adaptation: they don't use their eyes as much as their sense of hearing, but usually structures or functions are not lost unless the _loss_ implies some benefit. Relatively small eyes are still functioning eyes!\n\nOther bats that are much bigger, have large eyes and good eyesight; the so-called flying foxes.\nAnd to return to the question: a good reason that bats fly during the night is that they encounter less competition from other animals for their food, which may be insects, flowers, fruits, fish, etc.

Eye composition is different from species to species\n\nSome animals do not have cones in their eyes, which allow other animals to see in varying degrees of color.  Humans have three cone types:  red, blue, and green.  However, other cone types have been found in various animals.  Some aquatic species have been examined to have many more, some as many as 16 different types.\n\nEye shape is another factor.  Birds have eyes that can focus more sharply on a point than other animals.  The back of their eye is flatter and larger, allowing for a bigger picture to be taken in through the lens and pupil.  \n\nSome animals barely have a developed eye due to their natural habitat, such as cave dwellers and some burrowers.  Instead, other senses make up for the loss of sight.\n\nThere are even cases where eyesight is only for observation of movement in the area.  In other words, stand still and you will not get picked up.  Rhinoceros eyes are like that.\n\nThe Pupil, which is where light comes into the eye, gets larger in darker environments to let animals get around in low-light surroundings.  The muscles which control the pupil size (dilator and sphincter pairs) are stronger or larger in certain animals, giving them the ability to open the pupil to the point where the Iris is barely visible around it.  Cats are a good example.\n\nSome animals can even see in the infrared and ultraviolet, but this again goes tothe types of rods and cones present in the composition of the animal eye.

When i go to a cockfight i usually look when they are training them.. u know.. they usually have another bird there to kind of pick a fight with the other bird... and u can tell right away if  that bird will win the fight or not... LOOK AT BOTH... and from there decide which one will win....

They are likely following air currents-Flies dont think about where they are going-they dont really "think" at all, in terms of making decisions.  THey just have simple reactions to ari currents, heat, light, and chemical sensations (food)-If they are circling, its because there are air current moving in a circular motion, and they are following those.

If you are asking if other animals are concerned with how they look your answer is "of course". Think of any kind of male trying to attract a mate (peacock being an excellent example!). They try to have the biggest tails, brightest colors, or whatever will give them the best mate. if you are asking whether or not they can recognize themselves in the mirror, some apes can since they are so intelligent but so-called "lower mammals" cannot since they lack the brain capacity.

Each of the eyes are slightly recessed, and each eye points in a slightly different direction.  This makes it so that depending on which eye detects the most light, the insect is able to determine the direction of the light.  Humans, by contrast, find the location of light by having a lens which focuses the incoming light on the photo-sensitive retina at the back of the eye.

Here's an idea: have your object be a mirror, or at least something reflective.  Animals always think they see another animal in a mirror.  Cats will react by arching, puffing their tails, meowing, and even charging the mirror.

To see a snake or be bitten by one in your dream, signifies hidden fears and worries that are threatening you.  Your dream may be alerting you to something in your waking life that you are not aware of or that has not yet surfaced. The snake may also be seen as phallic and thus symbolize dangerous and forbidden sexuality. The snake may also refer to a person around you who is callous, ruthless, and can't be trusted. As a positive symbol, snakes represent transformation, knowledge and wisdom. It is indicative of self-renewal and positive changes.

Chances are they have a visiual cue to the colour of the berries. Its really a co-evolutionary thing. The tree wants to spread its seeds so it signals to the bird with bright red berries for example....come and eat me. Also many birds have very acute vision.....think of vultures flying high above the plains scanning for carrion. Animal senses can be very different from ours.\nCheers.

The animal kingdom doesn't have bias and lables like the human animal. If one actually finds attraction to the same sex, it is most likely a scent confusion. Most animals do their business based on scent.\n\nLearn all about spiders below.

Insects are attracted to the light reflected of the plants and they are most certainly NOT color-blind. Bees can see into the ultra-violet end of the spectrum farther than humans so they don't see the same colors we do.

Butterflies, like most insects, have two large compound eyes made up of hundreds of smaller lenses that combine images to form a larger picture of the insect's environment.  The resolving power of these individual eyes is not great, probably detecting levels of light and dark and colour perception, but the combination adds up much like the individual pixels of the image on your computer screen or TV set.\n\nLike most flying insects, butterflies also have three ocelli that are found on their heads between their eyes, basically forming a triangle on their 'forehead'.  These ocelli are sensitive to polarized light and assist the flying insect in navigation and balance, detecting the horizon and sky and direction of sunlight.
