Carapace surface somewhat uneven; front with two lobes; antero-lateral margin almost straight and cut into 2 teeth which are more prominent than those of H. nudus; there is an impressed H medially. Chelipeds smooth, stout and with long fingers irregularly toothed. Walking legs with setose margins.
Carapace: male 36 x 49.5 mm, female 31 x 42 mm.
Great variation; patterns resemble pebbles, among which these animals are often found. Commonly carapace grey-green with dots and patches of light grey and brown with a narrow white, or light-coloured marginal band and white crescents posteriorly. White ventrally. Chelipeds white with green and brown areas; fingers light brown with green streaks. Walking legs cream and green with dark brown or purplish pigment spots forming indistinct bands; dactyl light with 5 rows of dark seta. Eyestalk cream and grey with small dark brown dots; cornea black with silver flecks.
Littoral and perhaps slightly lower intertidally than H. nudus; under rocks on muddy beaches, in short burrows on tide flats and muddy lagoon margins. They tolerate considerable brackish or fresh water and even short periods out of water.
Resurrection Bay (60°0’N, 149°17’W), Alaska, to Gulf of California, Mexico; intertidal.
