Woodhouse's toad

L-shaped cranial crests between and behind the eyes; the post-orbital crest typically touches the long parotoid gland behind the eye. [1][2][3]

Gray, light brown or olive with dark blotches and spots, a white stripe down the centre of the back, and a speckled light underside. [1][2][3]

Males have a dark throat; each hind foot has two dark digging spades. [1][2][3]

Young toads often lack the back stripe and have reddish warts. [1][2][3]

Compared with the western toad: Western toad lacks cranial crests and has short oval parotoid glands; Woodhouse's has L-shaped crests and elongate glands longer than the eye. [1][2][3]

Compared with the great plains toad: Great Plains toad has a raised snout knob with V-shaped ridges and large white-bordered dark blotches. [1][2][3]

Burrows or hides under cover when inactive. [1][2][3]

Mostly nocturnal (adult activity at twilight into night in Washington), spending the day burrowed or hidden under debris or in rodent burrows; diurnal activity is not uncommon in other regions. [1][2][3]

Active from late April-May into October in Washington; inactive in cold months. Eats small terrestrial arthropods. [1][2][3]

Breeds in shallow still water from May into July; egg strings are wrapped around vegetation. [1][2][3]
