Ever seen one? Everything about the spiny king crab says “don’t touch!” We recently added two to our crab exhibit, courtesy of local prawn fishermen, who sometimes pull them up in traps!

The Scales on Moths and Butterflies
The wings, head parts of thorax and abdomen of the insect order Lepidoptera (moths and butterflies) are covered with minute scales. It is from this feature that the order ‘Lepidoptera’ (scale wing) derives its name. Most scales are lamellar, or blade-like and attached with a pedicel, while other forms may be hair-like or specialized as secondary sexual characteristics.
The lumen or surface of the lamella, has a complex structure. It gives color either by colored pigments that it contains, or through structural coloration with mechanisms that include photonic crystals and diffraction gratings.
Scales provide functions including insulation, thermoregulation, producing pheromones (in males only), and aiding gliding flight, but the most important is the large diversity of vivid or indistinct patterns they provide, which help the organism protect itself by camouflage or mimicry, and which act as signals to other animals including rivals and potential mates.

Dung Beetles Navigate by the Milky Way
A day in the life of a male dung beetle goes something like this: Fly to a heap of dung, sculpt a clump of it into a large ball, then roll the ball away from the pile as fast as possible. However, it turns out that the beetles, who work at night, need some sort of compass to prevent them from rolling around in circles. New research in Current Biology suggests that the insects use starlight to guide their way. Birds, seals, and humans also use starlight to navigate, but this is the first time it’s been shown in an insect.
