It is a crystal spider, or so you you think. "Strange" you think, this is an odd place to find such a creature, usually these are found in the desert and some have been found in a certain creepy forest far from here.. But nevertheless here it is. You recall reading about these once.
These Spiders received their name because the female is almost
completely transparent, though her innards are visible. This makes them
extremely hard to see. The male spider is more opaque, usually a dull white or
silver, with crystalline legs and waist. Some of the internal organs are
visible on certain male spiders but generally the genders can be told apart by
their colouration. This one is obviously a female.
You bet you can get quite a nice price from the zookeeper for this rare find.
