The Pineapple Spiky Isopod (scientifically known as Cristarmadillidium muricatum) is a highly sought-after dwarf isopod species prized for its unique, textured exoskeleton. Native to Spain, these miniature crustaceans feature a pale yellow to washed-out orange coloration and tiny, distinct bumps or "spikes" that make them look exactly like tiny, living pineapples.
