  1. 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.

  2. Pressure sensitivity and the tactile sense (excluding the lateral line)
    The star-nosed mole is famous for, well, its nose, but do you have any idea what these peculiar 'tentacles' are for? The answer is rather touching and, of course, convergent...

  2. Light producing chemicals: how to make bioluminescence
    The most remarkable luciferin in terms of its distribution is known as coelenterazine. This nitrogen-ring based molecule is found in nine separate groups, ranging from radiolarians to fish.

  3. Bioluminescence
    Flying through the air on a summer's evening or sparkling in the ocean you may see magical flashes of light that signal some of nature's most enchanting creatures, those that are bioluminescent.

    Arthropods are famous for their compound eyes, but some groups have had a fair crack at evolving the optically superior camera eye…

  6. 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…

  7. 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.
