Topics about "pinhole 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. Pinhole eyes in Nautilus and giant clam
    The pinhole eye has evolved not only in the Pearly Nautilus, but also in another group of molluscs, the bivalves and specifically the giant clams (Tridacna).

  10. 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.

  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.

  5. 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.
