Topics about "opsins" include:

  1. "Colour vision" in Firefly squid
    The Japanese firefly squid (Watasenia scintillans), which inhabits the deep ocean, has three visual pigments located in different parts of the retina that are likely to allow colour discrimination as they each have distinct spectral sensitivities.

  2. 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.

  3. Ancient opsins and vision in extinct animals
    Spectral tuning of the eye generally depends on key substitutions of amino acid sites in opsin proteins.

  2. Pufferfish (and inflation)
    Pufferfish are some of the most extraordinary fish to have evolved, especially because of their capacity to swallow water and inflate themselves to something like a football. Not only that but some representatives can be deadly to the unwary diner...

  3. 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.

  4. Camera eyes in cubozoan jellyfish
    On each of the four club-like extensions (rhopalia) near the base of the cubozoan jellyfish bell there are two camera-eyes, one pointing upwards and the other downwards.

  5. 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.

  6. 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.

  7. Infrared detection in snakes
    Warm-blooded rodents watch out! There are heat-sensing predators on the prowl...

  8. Infrared detection in animals
    Some snakes are famous for 'seeing' infrared, but did you know that their heat-sensing abilities are rivalled by some beetles that can detect forest fires over considerable distances?

  9. Taste in arthropods and mammals
    The ability to taste is obviously an essential component in the life of any animal, both to assess the potential quality of food, its nutrient capacities and also to detect toxins or other dangers.

  10. “Colour vision” in Firefly squid
    The Japanese firefly squid (Watasenia scintillans), which inhabits the deep ocean, has three visual pigments located in different parts of the retina that are likely to allow colour discrimination as they each have distinct spectral sensitivities.
