Topics about "crab spiders" include:

  1. Teeth in aquatic reptiles
    Aquatic reptiles tend to display one of three dentition types, well adapted to either seize and slice large vertebrate prey, pierce and gouge slippery fish, or entrap small prey such as crustaceans.

  2. Biological uses of silk: from webs to ballooning
    What material is so versatile that it can be used for capturing prey, building nests, communication and even cleaning? The answer: that most remarkable of biomaterials - silk.

  3. Silk production and use in arthropods
    Remarkably, fossil silk is known, especially from amber of Cretaceous age. Material includes both silk with trapped insects, possibly from an orb-web, and strands with the characteristic viscid droplets that are the key in trapping prey.

  4. 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…

  5. Telephoto eyes in animals
    Pursued by the paparazzi? Watch out for those animals equipped with telephoto lenses...

  6. 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.

  7. Nuptial gifts in insects and spiders
    Male dance flies lure females with a dead insect. Not very romantic, you might think, but it certainly does the trick. Hence, such nuptial gifts have evolved in numerous other arthropods...

  8. Thanatosis (feigning death) in spiders and insects
    Beetles that "play possum"? A rather interesting example of convergence…

  9. Crabs: insights into convergence
    You might think of crabs mainly as food, but this group is also highly instructive in terms of convergence…

  2. Mimicry in fungi
    Insects pollinating flowers are a familiar sight. But what happens when the "flower" is actually a fungus? Still "pollination", but now it is fungal spores. Read on to learn more about the fungi that mimic flowers...

  3. Vibrational communication in animals
    What on earth could an elephant or treehoppers have in common with a seismometer?

  4. 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.

  5. 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?

  6. Biological uses of silk: from webs to ballooning
    What material is so versatile that it can be used for capturing prey, building nests, communication and even cleaning? The answer: that most remarkable of biomaterials - silk.
