Not many creatures are as mysterious as the spider. Seems as though the more we learn about them, the more questions remain!
There are more than 850 documented tarantula species in the world. Some are as big as the human face while others are capable of shooting excrement as a defense mechanism. Then there are those that are, for some unknown reason, bright blue in color.
Experts suspect that the blue color serves an important purpose. However, “they don’t know what that [specific] function is yet.” The most plausible hypothesis has to do with sexual selection.
Scientists surmise that the flashy color helps tarantulas attract potential mates. However, Bor-Kai Hsiung of the University of Akron points out that this hypothesis is unlikely to be true since, despite the fact that tarantulas have eight eyes, they have very poor eyesight.
Blue spiders? I thought they were ugly enough being brown or black or yellow. Being blue really doesn't make them any prettier in my eyes, ya know what I mean?
Coffee out on the patio once more.
