I'm wondering if there are any animals whose eyes can zoom like a camera's lense, from wide angle to telephoto.

Raptors (diurnal birds of prey) have a region of their retina that provides a higher level of detail, virtually a zoom-in section.  They use this in spotting terrestrial prey from aloft.

Well, its true for some and false for others...\n\nBaleen: few inches across -> feed on small creatures\n\nSperm Whales : boy, these guys have huge throats and can swallow their prey whole.\n\n\nHowever, they can and do expand their throats.

Yes... the link below calls them optical tentacles, but that's a fancy way of saying "eyes".

Cats are nocturnal hunters. They have frontally placed eyes that provide good binocular (depth-sensitive) vision. In addition, their eyes are much more sensitive than ours to low light intensities, and they are able to see with very little environmental light (their minimum light detection threshold is up to 7 times less than that of humans). Due to this sensitivity, they could be subject to eye damage during the day, and their vertical pupils could be an adaptation to avoid this. The pupil is the "window" through which light reaches the retina, and a vertical pupil that can contract to a mere slit, in combination with the eyelids that close perpendicularly to this slit, is able to keep excessive light out. In contrast, the cat pupil expands to almost circular shape in the dark. They have other adaptations for night vision (see link).\n\nOther crepuscular/nocturnal animals also have vertical pupils, e.g. many snakes and geckoes.

:::::::) that is a long lens\n:::) Short lens\n:) a smiley face.\n\noh examples?\nWell such lenses as used in Video Projectors.\nCameras, Telescopes, Microscopes etc..

can I contact you directly? The CX31 will be good for you. UP VetMed has olympus microscopes....Please call 727-1058 (Manila number) and look for Frances, (Olympus dealer). We can give you a demo and help you choose... We can also give you a call...

EASY !!  A dolphin.. And I didn't just write that because it was mentioned on your list. You'll find dolphins in every room of my home, and I swim with them every time I get a chance to do so ! They are magnificent mammals !!

commmon one is Convex lens\n(with different angles, to magnify upto diff levels)\nbut for higher levels, it depends upto the magnifying object and distance also

diffrent types of some sort of animal.i think you like them very much.

Do you mean category of animals which are slow in reaction.\nSlender loris,sloths.

From now until hell freezes over. No telescope yet invented has that kind of magnification. Besides, Alpha Centuri is a star and your friend couldn't get within miles of it without being vaporized.

Hmm...the Hubble has surely helped with that, for one. The observories here on Earth are incredibly sophisticated, with high-powered lenses. When a probe drifts into space, I suupose it can still take distant pictures if it has battery power left.

I believe in the possibility of such an animal existing. There have been reports of similar animals in North America (San Francisco and Lake Champlain).

lions and tigers are one i know of. aka ligers/tygons. i believe wolves/dogs can be too. i would assume that there could be a lot more possibilities as long as they are in the same family of animal.

Have you tried maps.google.com?  It's quite brilliant and can give you a map, satellite shot, or a hybrid view of both.  The only iffy part will be how far it will let you zoom in.  But give it a try.

Gazelle???\nThats cruelty to animals!!lol

yes! they are amazing.  ligers are my favorite
