Topics about "compound eyes" include:

  1. Camera eyes of cephalopods
    The remarkable similarity between the camera eyes of cephalopods and vertebrates is one of the best-known examples of evolutionary convergence.

  2. Octopus and other cephalopods: convergence with vertebrates
    What could be more different from us than the alien-like octopus? Hold on. Look it in the eye and think again.

  3. Camera eyes in vertebrates, cephalopods and other animals
    Camera eyes are superb optical devices, so it is not surprising that they have evolved several times. But why, of all animals, in the brainless jellyfish? Or for that matter in a slow-moving snail?

  4. Beetles: insights into convergence
    The beetles are probably the most diverse animal group on earth, so it is not at all surprising that they provide many fascinating insights into convergence.

  5. Strepsipterans: convergent halteres and eyes
    Strepsipteran females spend their whole life inside a wasp. The males are rather more exciting, particularly in terms of convergence…

  6. Camera-like eyes in arthropods
    Arthropods are famous for their compound eyes, but some groups have had a fair crack at evolving the optically superior camera eye…

  7. Camera eyes in gastropod molluscs
    The fast-moving cephalopod molluscs are famous for their camera eyes, but why on earth have gastropod snails, which are not exactly known for their speed, evolved this superb visual organ at least four times?

  8. Compound eyes in ark clams
    Read on if you want to know more about bivalves with burglar alarms…

  9. Vision in echinoderms
    Among brittlestars and sea urchins we find visual systems that in some ways rival the arthropods in the form of compound eye-like structures.

  10. Corneal nipple arrays in insect eyes
    Anti-reflection coating? Not only on mobile phone displays, but also on insect eyes...

  11. Independent eye movement in fish, chameleons and frogmouths
    One of the most surprising convergences amongst animals is that seen between a small fish that lives in coral sands, known as the sandlance, and the lizards known as chameleons.

Topics containing the search term "compound eyes" are:

  1. Compound eyes in arthropods
    It is clear that amongst the arthropods as a whole the compound eye has evolved at least twice, and possibly even more times.

  2. Compound eyes in sabellid annelids
    Compound eyes have evolved convergently in the annelids, notably amongst the sabellids, where they evidently serve as an optical alarm system.

  3. Compound eyes in ark clams
    Read on if you want to know more about bivalves with burglar alarms…

  4. Corneal nipple arrays in insect eyes
    Anti-reflection coating? Not only on mobile phone displays, but also on insect eyes...

  5. Scanning eyes in molluscs and arthropods
    Some sea snails have a linear retina. What a hopeless arrangement, to see the world through just a narrow slit! Not quite, because they have come up with a rather intriguing trick to extend their visual field - and it's a trick too good to use only once.

  6. Camera-like eyes in arthropods
    Arthropods are famous for their compound eyes, but some groups have had a fair crack at evolving the optically superior camera eye…

  7. Strepsipterans: convergent halteres and eyes
    Strepsipteran females spend their whole life inside a wasp. The males are rather more exciting, particularly in terms of convergence…

  8. Transparent tissues: eyes, bodies and reflective surfaces
    Read on if you want to know about the numerous animal equivalents to the invisible man...

  9. Camera eyes of cephalopods
    The remarkable similarity between the camera eyes of cephalopods and vertebrates is one of the best-known examples of evolutionary convergence.

  10. Camera eyes in vertebrates, cephalopods and other animals
    Camera eyes are superb optical devices, so it is not surprising that they have evolved several times. But why, of all animals, in the brainless jellyfish? Or for that matter in a slow-moving snail?

  11. Agriculture in marine polychaete annelids
    Some polychaetes attach pieces of algae to their dwelling tube. Just for decoration? No, but for a much more substantial (and convergent) benefit...

  12. Vision in echinoderms
    Among brittlestars and sea urchins we find visual systems that in some ways rival the arthropods in the form of compound eye-like structures.

  13. Olfaction: insights into convergence
    Although olfaction is very widespread, there is abundant evidence for repeated convergence of key features, strongly suggesting that there really is an optimal solution to detecting smells.

  14. Loss of olfactory capacity in primates and cetaceans
    It is widely thought that reduced olfactory capacity in apes is linked to the development of acute vision, especially trichromacy.
