Giant Mimic Spider
The subspecies of giant spider known as mimic spider (often mistaken for a true mimic but actually unrelated) has evolved a unique exoskeleton to camouflage itself. Much as its smaller cousins mimic the colour and shape of flowers to lure prey such as bees, the giant mimic spiders which inhabit the numerous dungeons scattered across the land adopt the outward appearance of a treasure chest; an irresistible prize for any adventurer.
When the spider has found a suitable hunting ground it will curl up and wait. Specimens observed in the wild can remain in this state for months before suitable prey stumbles into its trap. Once its victim is close enough, a burst of webbing from its spinnerets, located in the ‘keyhole’, will immobilise them at which point the mimic spider will reveal itself and consume its victim.
Care should also be exercised when taking loose treasure from any dungeon in which giant mimic spiders are present. The creatures eggs often take the form of large coins, ingots of rare metals, gemstones and other valuables. Although the juvenile mimic spiders pose little threat, careless looting may lead to infestations in cities and other such places where the presence of giant, man-eating spiders is undesirable.

Inspired by thinking about mimics in Dungeons and Dragons and having the realisation that when opened all the way a treasure chest kind of resembles a spider body.
