Duttaphrynus melanostictus is commonly called Asian common toad, Asian black-spined toad, Asian toad, black-spectacled toad, common Sunda toad, and Javanese toad. It is probably a complex of more than one true toad species that is widely distributed in South and Southeast Asia.
The species grows to about 20 cm (8 in) long. Asian common toads breed during the monsoon, and their tadpoles are black. Young toads may be seen in large numbers after monsoon rains finish. Asian common toads occur widely from northern Pakistan through Nepal, Bangladesh, India including the Andaman and Nicobar Islands, Sri Lanka, Myanmar, Thailand, Laos, Vietnam, Cambodia, southern China, Taiwan, Hong Kong and Macau to Malaysia, Singapore, and the Indonesian islands of Sumatra, Java, Borneo, Anambas and Natuna Islands. They have been recorded from sea level up to 1,800 m (5,900 ft) altitude, and live mostly in disturbed lowland habitats, from upper beaches and riverbanks to human-dominated agricultural and urban areas. They are uncommon in closed forests.

Possible
About 20% of wildlife watchers report a Common Indian Toad sighting in Kaohsiung on a given day, based on 88 verified sightings from GBIF citizen-science data. It is the 2nd most-seen of the 8 amphibians we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
September
In that month about 40% of wildlife watchers report a Common Indian Toad in Kaohsiung on a given day, against about 10% in February, April and December, the lowest months. That is one of Kaohsiung's wettest months, with about 240 mm of rain against 25 mm in February.
Between 7 and 10 pm
Across all the parks we cover, that three-hour window holds the most Common Indian Toad sightings with a recorded time, and about 7 in 10 of them come between 6 pm and 6 am: it is mostly seen at night.
61st of 67
Of the 67 cities where we can rate Common Indian Toad sightings, Kaohsiung ranks 61st at about 20%. The best odds are in Makassar (Indonesia, about 80%), Jakarta (Indonesia, about 80%) and Malang (Indonesia, about 80%).
Same order: Anura
The closest relatives of the Common Indian Toad that you can see in Kaohsiung (order Anura, Frogs and Toads) are Asian Painted Frog (about 30%), Alpine Cricket Frog (about 20%) and Guenther's Frog (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Indian Toad is recorded against all the amphibians logged in Kaohsiung (88 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
