Golden Silk-orb Spider

Habitat:

In a Mangrove forest

Notes:

The name of the golden silk orb-weavers refers to the color of the spider silk, not the color of the spider itself. Yellow threads of their web shine like gold in sunlight. Xanthurenic acid, two quinones and an unknown fourth compound contribute to the yellow color. Experimental evidence suggests that the silk's color may serve a dual purpose: sunlit webs ensnare bees that are attracted to the bright yellow strands, whereas in shady spots the yellow blends in with background foliage to act as a camouflage. The spider is able to adjust pigment intensity relative to background light levels and color; the range of spectral reflectance is specifically adapted to insect vision. Wikipedia
