Topics about "polarised light" include:

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

  2. 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…

  3. Wire plants, moas and elephant birds
    Madagascar and New Zealand were once home to giant herbivorous birds. And the plants have not forgotten...    

  4. Trichromatic vision in mammals
    Who has not enjoyed the splash of colour in a market: gorgeous red peppers, the green of basil and what on earth are these purple vegetables over there? All thanks to trichromatic vision, another story of convergence.

  5. Bats: Insights into convergence
    Bats show a fascinating array of convergences, from echolocation to flight to nectar feeding. Vampire bats can even detect infrared radiation, while others might be able to see into the ultraviolet end of the spectrum.

  6. Monochromacy in mammals
    Underwater environments are dominated by blue light. Ironically, whales and seals cannot see blue, because they have independently lost their short-wavelength opsins.

  7. 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.

  8. 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.
