Brachionichthyidae (Handfishes)
Etymology: Pezichthys: Name from Greek 'pezo' (walking) and 'ichthys' (fish), referring to the ability of these fishes to walk on the sea floor using their hand-like pelvic fins and arm-like pectoral fins; amplispinus: A combination of the Latin amplus (large) and spina (spine, thorn) in allusion to the dense covering of long dermal spinules over its skin (Ref. 82446).

背面の脊椎 (合計) : 17 - 18; 肛門の骨: 7 - 9. Member of the genus Pezichthys with a bold colour pattern, long dermal spinules, a humped
nape and the posterior extension of the first dorsal-fin membrane is very short (i.e. interdorsal distance long). It also differs from its congeners in a combination of the following characters: esca small, 19–21% of illicium
length; illicium very slender, without dermal spinules, its length 16–20% SL, 2.5–3.1 times in head length in adults; head length 4.9–6.2 times snout length; snout long, length 8–10% SL; eye 6.2–7.7 times in head length; body moderately robust, maximum width 30–38% SL; interorbital width 8–11% SL; scale bases subcircular with relatively long bifurcate spinules (except for those closely associated with pores of the acoustico-lateralis system); spinules variable in length over body; dorsal-fin elements with spinules, membranes of fins mostly naked; first dorsal-fin base length 18–20% SL; second dorsal-fin rays 15–16 (usually 16), fin base 55–63% SL; length of second dorsal-fin spine 1.4–1.9 times length of longest ray of second dorsal fin; anal-fin rays 7–9; upper body variegated, lacking dark spots or streaks; caudal fin not covered with fine spots (Ref. 82446).
Body shape (shape guide): elongated.
