Description

Head deeply concave with only supraorbital ridges; interorbital space broader than the upper eyelid; tympanum very small or indistinct; first finger does not extend beyond second; toes with single subarticular tubercle, no tarsal fold; parotid is as long as the head; body with irregular porous tubercles. Snout-vent length 130-132 mm.Color: Uniform brown. Cranial crest and tips of digits dark brown.Considered a very rare highland species.This species was highlighted in News of the Week:January 8, 2018: Biodiversity survey work is a critical step to assess and monitor the state of amphibians in any given area, even protected ones. A herpetology survey conducted by Shrestha and Shah (2017) in Manaslu Conservation Area in western Nepal along the China border illustrates this in a multi-pronged strategy. Their survey included traditional methods such as literature review, visual encounter surveys, patch sampling and opportunistic observations combined with less commonly used ethnographic questionnaire. Of the 21 species documented by the literature, they found 5 species including a new record for the area. Of the 8 species of documented amphibians, only Duttaphrynus himalayanus was encountered in the field; three frog species were noted in interviews as popular food items. The authors note this local ‘delicacy’ could have significant impact on biodiversity and show how taking into account human use is an important part of survey work. (Written by Michelle Koo)

Life History, Abundance, Activity, and Special Behaviors

provided by AmphibiaWeb articles
Life history notes: Bufo himalayanus is a mountain species; primarily nocturnal; however, it is often seen moving about in broad day light among rocks and vegetation feeding on grasshoppers, moths, ants, and other invertebrate animals. It rests during the day under stones or in fissures and holes in the ground. Breeding activity starts after a downpour, during May-July; males croak in low tone with "curr, curr" repeated several times. Eggs are laid in a double string of jelly in shallow pools along torrents. Tadpole: Head flat, body darker, belly bulging, tail weak, low fins; naris slightly nearer to eye than snout; eyes small and sunken; oral disc anteroventral, labial tooth row formula typically bufonid: 2(2)/3, beak serrated, oral papillae lateral; color uniformly black, ventrum lighter. The tadpoles are found, at a high elevation in the Himalayan range, in small, calm pools along torrents, with algal vegetation. Total length of tadpole 28-30; tail 19-20 mm. The toad hibernates during the winter under stones and in fissures in the ground from September to March. The karyotype number recorded for this species is 22 (Chatterjii and Barik, 1970).

Duttaphrynus himalayanus

provided by wikipedia EN

Duttaphrynus himalayanus, also known as the Himalaya toad, Himalayan toad, Himalayan broad-skulled toad, and Günther's high altitude toad (among others), is a species of toad that is widely distributed throughout the Himalayan mountains. The Yunnanese populations are sometimes considered a separate species, Duttaphrynus cyphosus.[1][2]

Description

Bufo himalayanus.jpg

The crown is deeply concave, with low, blunt supraorbital ridges. The snout is short and blunt, the interorbital space is broader than the upper eyelid, and the tympanum is very small and rather indistinct. The first finger does not extend beyond the second, the toes are half or two-thirds webbed, with single subarticular tubercles, two moderate metatarsal tubercles, and no tarsal fold. The tarsometatarsal articulation reaches the anterior border of the eye or the tip of the snout. Upper parts have irregular, distinctly porous warts, the parotoids are very prominent, large, and elongated, at least as long as the head. They are uniform brown in color. Males do not have vocal sacs.[3]

From snout to vent, they measure 130 mm (5 in).

Distribution and habitat

This species is found from Azad Kashmir in Pakistan through northern India and adjacent Bangladesh, Bhutan, and Nepal to southern and central Tibet and northwestern Yunnan in China. Its range might extend into Myanmar.[2] It occurs at the elevations of 1,000–3,500 m (3,300–11,500 ft) above sea level. It inhabits mountain forests and shrubland near streams, and also is found in the vicinity of seepages and fields. This high-altitude species can also occur in the evergreen forests of the foothills.It is largely a terrestrial toad. Breeding takes place in hill streams, small pools, and puddles.[1]
