Members of this phylum have large eyes and excellent vision.?

You are clearly referring to the Class Cephalopoda (squids, octopi, etc.).  It is in the Phylum Mollusca.  Most molluscs, however, have moderate to poor eyesight relative to arthropods and cephalopods (snails and clams are molluscs) so saying the Phylum Mollusca is the correct choice is a bit off.

ooooh because their ginormous and big

There are viper fish, deep sea anglers, and brotulids to name a few. Some are blind but some have bioluminescence, or in other words they can glow in the dark and have huge eyes. They came to live so deep very gradually over millions of years.

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.

Birds and reptiles have better color vision than humans\nMost mammals have poor color vision by human standards.\nPrimates have vision like humans.\n\nColor vision arises from photoreceptor cells in the eye called cones. \n\nBirds and reptiles have four different kinds that are sensitive to four different wavelength ranges. Most mammals have only two types having lost half somewhere in the distant past due to mutations. Most of the mammals that lived in the shadow of the dinosaurs were nocturnal, so color vision wasn't very useful to them anyway.\n\nPrimates have the same two kinds of cones that mammals, birds and reptiles have in common, but unlike other mammals they have a third type which is unique to primates, it arose via a mutation and allows human style color vision. It's sort of an awkward compromise when compared with birds and reptiles though. They can see UV light, we cant'\n\nI'd add that any nocturnal animal regardless is less likely to have good color vision, because overall light intensity is sensed by a different kind of photoreceptor cell (rods) and good night vision requires more rods than cones. You can't have your cake and eat it too.\n\nI don't know much about fish and amphibians. \n\nSome insects have very good color vision in tems of color perception. Any of the ones that co-evolved with flowering plants would see color better than usb ecause of that extended spectrum thing. Although the specifics of their vision systems aren't familiar to me.\n\nI only know the stuff on bird, mammal and primate vision because of an article in a recent issue of Scientific American.

I believe such an animal the term low-light vision is used. Such as an owl. Most birds are sight-driven and have excellent vision. The owl has excellent day vision and excellent night vision because its pupils can dialte to allow moonlight or starlight sufficient lighting to see by. This is not to be confused with infravision which is totally different than low-light vision. That would allow the heat an animal gives off to be seen in the dark.

The answer is D.  Animals with large eyes (think owls) are usually nocturnal.   Larger eyes allow for more light to come in.

In most mammals, the pupil of the eye is round but in many of the flesh-\neaters such as the domestic cat, it becomes a vertical slit in bright \nsunlight and widens to cover most of the pupil in darkness. That is why \nthey see so well at night. In the eyes of the kangaroo and some hoofed \nanimals, notably the goat, the pupil is a horizontal slit. The eyes of \nmany animals shine at night because of a peculiar mirror, on the retina \nat the back of the eyeball, which reflects light; so that a cat's eyes have a \ngreen glare and those of alligators and crocodiles shine red. Such \neyeshine is found in many other kinds of animals including various \nmammals, sharks, sturgeons, and some moths, but not in birds nor \namphibians: and in all colors except violet and white.\n\nSwift animals, like the antelope, usually have large eyes. Nocturnal \nanimals like the deer mouse and flying squirrel, have also developed \nvery large eyes which enable them to see better and evade their many \nenemies. Others, which live mostly in tunnels, like the meadow mice, \nshrews and moles, have tiny weak eyes. Some, like the earthworm, are \nblind. Land snails have eyes on tentacles with which they can see \naround a corner, but leeches merely have "eye spots " or none at all. \nCrawfish and crabs have eyes on short stalks. Spiders have from 2 to 8 \neyes. Many insects have huge compound eyes -- the dragonfly has from \n20 to 25 thousand tiny lenses in a honeycomb pattern -- and some, like \nthe grasshopper, also have three little "simple" eyes for close vision. \nBirds have the keenest eyes and those of the hawks, eagles and vultures \ncan see small objects at incredible distances.

Richard Dawkins has two wonderful chapters on cnidarians (jellyfish) and poriferans (sponges) in 'The Ancestor's Tale.'\n\nCnidarians have two body plans, the medusa (jellyfish) and the polyp (sea anemones and hydras).  Polyps often reproduce by budding and can make huge colonies of organisms.  The portuguese-man-of-war is actually a complex colony of medusa and polyp forms.  (BTW, he has a great discussion about how the stinger cell in jellyfish may be the most complex structure in any cell anywhere in the animal and plant kingdoms. Way cool!)\n\nPoriferans (sponges) are even simpler organisms.  Although they are ostensibly multicellular organisms, with several types of cells, these cells don't organize themselves into specialized tissues and organs. Sponges are able to reproduce both asexually and sexually.\n\nSo the evolutionary significance is that an individual is basically a colony.  As such they are right at the boundary between single-celled and multi-celled creatures.  They demonstrate how multi-celled organisms could arise as a colony of cooperating single-cells.

IFu are very much intreasted in studying that spider then take a book of PHYLUM ARTHROPODA  in invertebrate classification \nand identify the feautures like spines legs

My 1st reaction would be to say the lemur - but thats only coz their eyes are so big in comparison to the rest of their body.....the elephant is more in proportion but obviously a much bigger animal....I think this is a trick question so I will say the elephant has bigger eyes! Am I right??

They have excellent eyesight and watch for movement.

I believe, that you are looking for amoeba.\nAmoeba's are from the kingdom: Zooplankton,  which has animal like characteristics. The Amoeba, in particular, belongs to the phylum: sarcodina which have characteristics such as having a coinceboid shape (no shape), and being able to flow by extending it's cell membrane to form false feet (pseudopod).\n\nBut, there are still several others that can be classified in this category: Paramecium cordatum (from the phylum: ciliophora), Trypanosoma gambiensis (from the phylum: mastigophora), and Plasmodium vivox (from the phylum: sporozoa)\nAs you see, there is more then one choice in this matter.\n\nHope this helps!
