Extremely small (0.4–0.6 in / 1–1.5 cm), semi-translucent to light brown-gray carapace with fine setae on legs that trap food. Delicate legs and compact carapace make them appear like tiny, moving specks in densely planted tanks.
Bright purple to dark violet body with striking orange to yellow eyes. Carapace measures about 1–1.5 inches (2.5–4 cm). Legs may show lighter hues or striping. Distinctive glowing eyes give them a unique 'vampire-like' look.
