Males have a carapace up to 41.9 mm × 26.9 mm (1.6 in × 1.1 in) across, while females are larger, at 50.5 mm × 32.5 mm (2.0 in × 1.3 in).[1] The eyes are immobile and unpigmented.[1]
The species was originally described as Austinograea yunohana in 2000.[2] It was transferred in 2007 by New Zealand marine biologist and carcinologist Colin McLay to his new genus, Gandalfus, named after the character Gandalf from The Lord of the Rings.[1]
Gandalfus zunohana is found on hydrothermal vents on the eastern edge of the Philippine Sea Plate south of Japan.[2] It lives at shallower depths than other members of the family Bythograeidae, at 420–1,380 m (1,380–4,530 ft).[1]
